TPS2371PWR - Legacy PoE Power Interface Switch | TI
The Texas Instruments TPS2371PWR is a legacy IEEE 802.3af-compatible power interface switch for Power over Ethernet powered devices, with programmable inrush current limiting and an 8-pin TSSOP package. It is designed for PoE PD applications requiring controlled power admission, input protection, and startup behavior. A power interface switch is an integrated semiconductor that sits between a PoE source and the powered equipment. It controls how power is applied to the downstream circuit, helping prevent excessive startup current, protecting source equipment, and defining the operating conditions seen by the load. In the broader power-management hierarchy, this device belongs to the PoE interface-switch and power-management IC category rather than a conventional voltage regulator. The verified manufacturer information identifies the TPS2371 as a legacy IEEE 802.3af-compatible power interface switch for PoE PDs. The datasheet search result also states that IEEE 802.3af permits an inrush current of 400 mA for 50 ms, limiting the load capacitor to approximately 180 µF. The programmable inrush current limit removes that restriction and permits a larger capacitor with lower startup current. The key design trade-off is between fast startup and controlled power admission. A lower programmed inrush limit can reduce stress on the PoE source and downstream components but may lengthen startup, while a higher limit can start a larger load more quickly but places greater transient demand on the source. The device is intended to simplify legacy PoE PD power-interface designs while preserving the external 8-TSSOP footprint. Typical applications include legacy PoE powered devices, powered Ethernet endpoints, IP cameras, VoIP phones, access-point equipment, and other IEEE 802.3af-compatible PDs. The part should be selected only after checking the source's PoE classification, available power, startup timing, protection requirements, and downstream capacitance against the complete manufacturer datasheet. For implementation, follow the manufacturer application guidance for input capacitance, current-limit programming, surge protection, layout, and exposed-pad or thermal requirements where applicable. Do not infer ratings, thresholds, or timing values from distributor descriptions alone; verify them in the official TPS2371 datasheet before releasing a production design. This page consolidates verified manufacturer and distributor descriptions, separates documented facts from unavailable parameters, and provides engineering guidance for comparing this legacy PoE interface switch with possible replacements.

The Texas Instruments TPS2372-3RGWT is an IEEE 802.3at and IEEE 802.3bt high-power Power over Ethernet (PoE) powered device (PD) interface controller supporting up to 60 W (Type 3) in a 20-pin VQFN (RGW) 5x5 mm package. A PoE PD interface controller is the front-end power management IC that resides in the powered device of a PoE system. It performs detection, classification, inrush current limiting, and disconnect identification, then hands off power to an isolated or non-isolated DC-DC converter. It sits at the top of the PoE power hierarchy: PoE PD controller -> PoE power interface IC -> power management IC -> semiconductor. Key features include support for IEEE 802.3at (Type 2) and IEEE 802.3bt (Type 1-4) classes, Automatic MPS (Maintain Power Signature) that reduces standby power in battery-backed applications, and Autoclass that enables downstream converters to lower power losses. Protection circuits cover undervoltage lockout, overcurrent, and thermal shutdown. PGOOD status indication allows clean sequencing of the downstream converter. The TPS2372-3 variant is optimized for 60 W applications with low internal switch resistance, while the TPS2372-4 variant supports up to 90 W Type 4 designs. According to the Texas Instruments product page, the TPS2372 family contains all features needed to implement an IEEE 802.3at or 802.3bt (draft) Type 1-4 powered device. Detection and classification compliance ensures interoperability with all standard PSE (power sourcing equipment) vendors. Typical applications include LED lighting fixtures, IP security cameras, wireless access points, 5G small cells, VoIP telephones, and network switches. Its wide input tolerance (0 V to 57 V per distributor data) and integrated pass transistor reduce bill-of-materials count versus discrete MOSFET solutions. For design, budget the inrush current limit against downstream converter input capacitance, and use the PGOOD output to enable the converter only after PoE handshake completes. This page adds distributor pricing, drop-in alternatives, and practical design notes beyond the manufacturer datasheet.
TPS2372-4RGWT - IEEE 802.3bt PoE PD Controller 90W | TI
The Texas Instruments TPS2372-4RGWT is a 1-channel IEEE 802.3bt (Type 1-4) Power over Ethernet powered-device (PD) interface controller supporting up to 90 W, with an integrated low-RDS(on) internal pass switch, supplied from 0 V to 57 V in a 20-pin VQFN (5x5 mm) package with exposed pad. A PoE PD controller is the front-end power-management IC that resides inside a powered device such as an IP camera, wireless access point, or LED luminaire. It performs detection, classification, and inrush-current limiting so the power-sourcing equipment (PSE) in the network switch can safely identify and power the device over the Ethernet cable. Within the power-management hierarchy, it sits between the RJ45 magnetics/diode bridge and the isolated DC-DC converter that generates the system rails. Key features of the TPS2372-4 include support for IEEE 802.3at (PoE+) and 802.3bt draft Type 1-4 power classes, Automatic MPS to maintain power through low-load periods, and Autoclass for accurate power allocation reporting to the PSE. The -4 variant's low internal switch resistance enables full 90 W Type 4 operation, while the related TPS2372-3 supports up to 60 W. Technically, the device integrates the detection and classification signature resistors, a hot-swap MOSFET with current limiting, thermal protection, and fault supervision. The low switch resistance minimizes conduction losses at the multi-ampere input currents demanded by Type 3 and Type 4 systems, improving overall efficiency and reducing heatsinking requirements. Typical applications include 802.3bt high-power LED lighting, 5G small cells and wireless access points, PTZ IP security cameras, and industrial networked devices where a single Ethernet cable delivers both data and up to 90 W of power. When designing, place the IEEE signature components (the 24.9 k-ohm detection resistor and classification resistors) directly at the VDD/RTN pins, and verify the inrush and operating current limits against your isolated converter's input capacitance to avoid nuisance tripping during startup.

TPS23730RMTR - 802.3bt PoE PD Controller 60W | Texas Instruments
The Texas Instruments TPS23730RMTR is an IEEE 802.3bt Type 3 (Class 1-6) Power over Ethernet powered-device (PD) controller with an integrated high-efficiency current-mode DC-DC controller, supplied in a 45-pin VQFN (RMT) package measuring 7x5 mm and rated from -40C to +125C. It integrates a robust 100-V, 0.3-ohm (typ) hotswap MOSFET and supports power levels up to 60 W, and is EA Gen 2 logo-ready as a PoE 2 PD controller. A PoE PD controller is the interface IC that negotiates power with a Power Sourcing Equipment (PSE) port, performs detection, classification, and inrush current limiting, then hands off to a DC-DC converter that produces the equipment's usable rails. Within the power-management hierarchy it spans both the PoE interface layer and the switching-regulator control layer, replacing the two-chip discrete solutions used in earlier 802.3at designs. Key differentiating features include complete single-chip 802.3bt Type 3 compliance for Class 1-6 power levels, an allocated power indicator output, support for parallel or split power operation, and a current-mode controller optimized for both flyback and active-clamp forward (ACF) topologies. The integrated 100-V hotswap MOSFET with 0.3-ohm on-resistance removes an external pass device, reducing BOM count and conduction losses at multi-amp input currents. On the technical side, the DC-DC controller section supports high-efficiency isolated and non-isolated conversions from the 48-V PoE rail, with current-mode control providing inherent cycle-by-cycle current limiting and simple loop compensation. EA Gen 2 (PoE 2) readiness means the TPS23730 passes certification requirements for next-generation high-power PoE deployments, supporting up to 60 W at the PD for Type 3 Class 6 operation. Typical applications include 5G small-cell radios and network cameras that draw 40-60 W, wireless access points, LED lighting drivers powered from Ethernet, and industrial IP intercom or display terminals where a single Cat5e cable must carry both data and power. The 60-W envelope with allocated power indicator outputs makes it particularly suitable for two-pair Type 3 PD designs. Design-wise, validate the transformer or forward magnetics for the full Class 6 power level and provide adequate PCB copper under the RMT exposed pad for hotswap MOSFET conduction and switching losses; TI's TPS23730EVM-093 reference design is the recommended starting point for new layouts.

TPS23734RMTR - IEEE 802.3bt Type 3 PoE PD Controller | TI
The Texas Instruments TPS23734RMTR is an IEEE 802.3bt Type 3 Class 1-4 Power-over-Ethernet (PoE) Powered Device (PD) controller with an integrated high-efficiency DC-DC controller, housed in a 45-pin VQFN (RMT) package measuring 7 mm x 5 mm. As a PoE 2 / EA Gen 2 logo-ready PD controller, it includes a robust 0.3 ohm (typical) internal hotswap MOSFET and supports power levels up to 30 W operation across 802.3bt Type 3 and 802.3at PD applications. The device integrates an internal PWM controller intended for flyback or active-clamp forward primary-side-regulated DC-DC topologies, eliminating the need for an opto-isolator and significantly simplifying isolated PoE supply designs. An IEEE 802.3bt PD controller is a specialized interface IC that negotiates power classification with a Power Sourcing Equipment (PSE) over twisted-pair Ethernet cabling, then converts the incoming PoE voltage into a regulated supply rail for downstream loads. These devices sit at the front end of PD hardware such as IP phones, wireless access points, security cameras, and IoT gateways, and they bridge the PoE interface standard with the application board. Within a power-management taxonomy the TPS23734 is part of: PoE PD controller -> Power-over-Ethernet IC -> Power Management Interface IC -> Power Management -> Semiconductor. Key differentiating features of the TPS23734RMTR include integrated primary-side regulation (PSR) which removes the secondary-side feedback optocoupler and TL431, an automotive temperature grade of -40 C to +125 C, and EA Gen 2 logo-ready compliance with the IEEE 802.3bt specification. The internal hotswap FET minimizes external component count and the device supports all five 802.3bt classes (Class 1 through Class 4), enabling a single PCB design to address 15 W, 30 W, and intermediate power levels in the same hardware platform. The architecture pairs a hardened PoE interface front-end (signature, classification, and inrush control) with an integrated current-mode PWM controller optimized for high-efficiency flyback conversion. Primary-side regulation samples auxiliary winding voltage during the MOSFET off-time to close the loop without secondary-side feedback parts. This topology reduces BOM cost, improves MTBF, and avoids the bandwidth and aging limitations of opto-isolated feedback. Typical applications for the TPS23734RMTR include PoE-powered wireless access points (Wi-Fi 6/6E APs), IP surveillance cameras, VoIP phones, IoT and smart-building sensors, and industrial PoE-powered controllers where isolated, regulated 5 V, 12 V, or 24 V rails are required from 42-57 V PoE inputs. Up to 30 W operation covers most single-board PoE appliances. When designing with this device, pay close attention to the transformer design for PSR applications - the auxiliary winding ratio directly sets output voltage accuracy, and proper RCD snubber sizing is essential for efficiency. Layout should keep the hotswap path short and place the bootstrap capacitor immediately adjacent to the BOOT pin to avoid PWM-controller UVLO. Operating ambient temperature may limit output power; derate using the application-specific thermal profile. This page synthesizes distributor pricing, drop-in alternative MPNs, and practical design notes not consolidated in the manufacturer datasheet, giving engineers an actionable reference for selecting the TPS23734RMTR in new PoE PD designs.
TPS23758RJJR - IEEE 802.3at PoE PD Flyback Controller | TI
The Texas Instruments TPS23758RJJR is an IEEE 802.3at Power over Ethernet (PoE) powered-device (PD) controller with an integrated 150-V power FET and a current-mode, no-opto synchronous flyback DC-DC controller, housed in a 24-pin VSON (6 mm x 4 mm) surface-mount package. It supports 802.3at Type 1 power levels up to 13 W from the PoE link. A PoE PD interface is the circuit that negotiates and extracts power from Ethernet cabling per IEEE 802.3at, sitting within the hierarchy of power management ICs (PoE controller -> power interface -> power management IC -> semiconductor). It performs detection, classification, inrush control, and load switching for devices powered over the data cable, such as IP cameras and wireless access points. Key differentiating features include high integration: the TPS23758 combines the PD interface, a 150-V switching power FET, and the DC-DC controller in one die set, reducing external component count. Primary-side regulation (PSR) eliminates the optocoupler and secondary-side feedback network, while spread spectrum frequency dithering (SSFD) reduces EMI peak emissions. Advanced startup supports efficient boot sequencing from the PoE input. Technically, the device operates as a current-mode flyback controller optimized for isolated or non-isolated PoE conversion topologies. The no-opto sync architecture uses transformer auxiliary-winding sensing for output regulation, improving reliability and shrinking the solution footprint compared with conventional optocoupler flybacks. The integrated 150-V FET withstands PoE input transients common on long cable runs. Typical applications include IEEE 802.3at Type 1 (13 W) IP network cameras, wireless access points, VoIP phones, and other size-constrained PoE-powered endpoints where board space and EMI compliance are critical constraints. A key design consideration is transformer selection: the no-opto PSR scheme depends on accurate auxiliary-winding design, and TI recommends following the TPS23758EVM-080 reference design transformer specification for Type 1 applications.

TPS2375PW-1 - IEEE 802.3af PoE PD Controller, 100V | Texas Instruments
The Texas Instruments TPS2375PW-1 is an IEEE 802.3af Power over Ethernet (PoE) Powered Device (PD) controller with auto-retry fault recovery, a 100-V rating, and a true open-drain power-good output, housed in an 8-pin TSSOP (PW) package rated for operation from -40C to +85C. Power over Ethernet is a technology defined by the IEEE 802.3af standard that delivers DC power alongside data over standard Category 5 Ethernet cabling. A PoE system consists of Power Sourcing Equipment (PSE), such as a PoE switch or midspan injector, and a Powered Device (PD), such as an IP camera, wireless access point, or VoIP phone. The PD controller is the interface IC that performs detection, classification, and inrush-current control so the PSE can safely identify and power the end device. It sits at the entry point of the PD power path, ahead of the isolated DC-DC converter that generates the system rails, and therefore forms part of the broader power management IC hierarchy. Key features of the TPS2375PW-1 include full compliance with the IEEE 802.3af specification, with device thresholds offset by 1.5 V from the standard to account for input diode-bridge drops, ensuring polarity-insensitive operation. The -1 suffix denotes second-generation silicon with a 100-V absolute maximum rating and a true open-drain power-good (PGB) output. Its defining differentiator is auto-retry: after an overcurrent fault, the device automatically attempts to re-enable the pass MOSFET instead of latching off, eliminating the need for a power cycle. An integrated 0.58-ohm sense element plus classification resistor support (Class 0-3, up to 12.95 W at the PD) reduces external component count. Architecturally, the controller integrates the detection and classification signature circuits, a 57-V rated hot-swap pass-element gate driver, current-limit and foldback protection, and thermal shutdown. The DETC pin manages detection behavior and the CLS pin programs the power class. During startup, controlled gate slew limits inrush current so the PSE is not tripped by capacitor charging; during a fault, the current limit engages and the auto-retry timer restarts the pass element once the fault clears. Typical applications include IP network cameras, 802.11 wireless access points, VoIP telephones, and PoE-enabled lighting or access-control nodes - anywhere a device must draw 13 W or less from an Ethernet port. The part pairs naturally with a flyback or forward converter to generate isolated low-voltage rails. A key design consideration is sizing the bulk input capacitance so inrush stays within the PSE inrush budget, and ensuring the external pass MOSFET and TVS diode meet the 100-V transient environment. Prices on this page are as of 2026-10-19 (LCSC from $2.3057).

The Texas Instruments TPS2378DDAR is an IEEE 802.3at high-power Power over Ethernet (PoE) powered device (PD) interface controller that continuously handles up to 0.85 A using a low 0.5-ohm internal switch, housed in an 8-pin SO PowerPAD (DDA/HSOIC) package rated from -40C to +85C. A PoE powered device interface is the front-end circuit that lets a network-enabled product safely draw power over the same Ethernet cable that carries its data. Sitting at the top of the power management hierarchy, it performs detection, classification, inrush current limiting and load switching per the IEEE 802.3af and 802.3at standards, before handing a regulated rail to downstream DC-DC converters. The TPS2378 is TI's PD interface controller in that family. Key features include support for both IEEE 802.3at type-2 (PoE+, up to 25.5 W at the PD) and 802.3af (PoE, class 0-3) operation, an auxiliary power detect (APD) input that gives priority to an external DC supply, and the internal 0.5-ohm pass switch that eliminates a discrete MOSFET. Automatic classification with the CLS pin and a T2P output signal simplify type-2 system designs. Architecturally, the TPS2378 integrates the IEEE detection and classification state machines, a thermal shutdown, and a gate driver for the internal pass element. The PowerPAD exposed pad on the DDA package provides enhanced thermal dissipation, which is what enables continuous 0.85 A operation through an on-chip switch. The 37-page TI datasheet documents the full state machine timing and threshold levels. Typical applications include IP security cameras, wireless access points, VoIP phones, PoE lighting (LED) drivers, and networked industrial sensors that must comply with 802.3at type-2 power budgets. Design-wise, the APD feature allows the PD to prefer a wall-adapter input; tie APD appropriately if auxiliary power is not used. Verify inrush compliance (type-2 class events) during qualification. This page adds distributor pricing, drop-in alternatives, and practical design guidance beyond the TI datasheet.

A Power-over-Ethernet PSE controller is a specialized mixed-signal IC that sits inside an Ethernet switch, midspan, or PoE injector and safely delivers DC power over the twisted-pair cabling to a Powered Device (PD) such as a wireless AP, IP camera, or lighting fixture. In the broader hierarchy, the TPS23881ARTQT is a PoE controller -> power management IC -> power switch IC -> interface IC -> semiconductor, enabling compliance with the IEEE 802.3bt (formerly 802.3at/at+bt) standard. Key features include support for 4-pair Type-3/Type-4 operation delivering up to 90 W per port, 200 mΩ current-sense resistors per pair for accurate current monitoring, integrated 0.5 Ω MOSFET gate drivers, I2C programmability with 16 addresses, autonomous semi-auto and manual modes, comprehensive per-port telemetry (voltage, current, temperature), and legacy PD detection. The 200 mΩ RSENSE significantly reduces power dissipation versus the 0.5 Ω external FET architectures used in older PSE designs. Architecturally, the TPS23881ARTQT integrates eight independent port controllers, each containing detection, classification (including 4-event classification for Type-3/4), inrush control, and disconnect monitoring. A precision bandgap reference and on-chip ADC support accurate current/voltage measurement. The device operates from a 44 V to 57 V supply (PoE nominal 48 V) and includes per-port thermal protection and current-limit foldback. Typical applications include enterprise-class 802.3bt PoE++ switches, Wi-Fi 6/6E access points, PTZ IP cameras, PoE lighting controllers, 5G small-cell backhaul, and industrial PoE midspans. Pairing with TI's FirmPSE system firmware enables scalability to 48-port systems across multiple cascaded TPS23881 devices. When designing with this device, ensure adequate bulk capacitance on the 48 V rail, observe 4-layer PCB layout recommendations for thermal management, and reserve I2C lines for multi-device addressing. The autonomous mode reduces firmware overhead for cost-sensitive designs while the I2C interface unlocks per-port telemetry in managed switches.
TPS23881RTQR - 8-Ch 802.3bt PoE PSE Controller | Texas Instruments
The Texas Instruments TPS23881RTQR is an 8-channel, 4-pair, Type-4 Power-over-Ethernet (PoE) Power Sourcing Equipment (PSE) controller housed in a 56-pin VQFN (RTQ) package (8x8 mm). It complies with the IEEE 802.3bt standard, supports 200-mΩ RSENSE current sensing, and delivers up to 90 W per port across 2-pair or 4-pair configurations with auto-mode and semi-auto-mode operation. A Power-over-Ethernet PSE controller is the device that injects DC power onto Ethernet cable pairs in compliance with IEEE 802.3af/at/bt. The PSE resides inside the network switch or midspan hub and negotiates detection, classification, and inrush with the Powered Device (PD) at the far end of the cable. Within the broader system hierarchy, the TPS23881 belongs to Power Management ICs > Power Switch / Hot Swap > PoE PSE Controllers, and integrates the analog front end, MOSFET drivers, signature detection, and an I2C/SPI management interface so that an external host or firmware can configure port-by-port behavior. Key features of the TPS23881RTQR include 200-mΩ sense resistance for high-efficiency current monitoring, integrated 0.1-ohm hot-swap FETs per channel, autonomous or host-controlled port management, individual port current and voltage readback, and robust protection with current-limit, inrush timeout, and thermal shutdown. The 56-pin VQFN RTQ package with an exposed thermal pad delivers a low θJA, allowing all 8 channels to operate at 802.3bt Type-4 power levels without external heatsinking on typical 4-layer PCBs. From an architectural standpoint, the TPS23881 uses per-channel analog current-sense amplifiers and 12-bit ADC telemetry, paired with a digital control engine that runs TI's FirmPSE firmware. This dual firmware architecture allows multi-port scalability (up to 48 ports across multiple TPS23881 devices) while keeping the host CPU free for higher-layer PoE management functions. The IC supports 1-bit legacy detection, 4-point class detection, and 802.3bt multi-event classification for reliable PD discovery.

When designing with this part, ensure adequate copper area on the EP pad (TI recommends ≥4 thermal vias to an inner plane), follow the layout guidance in the datasheet's layout section, and size the upstream 54 V supply per the worst-case 4-pair load. Pay close attention to inrush and turn-off sequencing to avoid PD-side latch-up. This page synthesizes distributor pricing, cross-reference alternatives, and practical layout notes that extend beyond the manufacturer datasheet.
TPS2514AQDBVRQ1 - Automotive USB DCP Controller | TI SOT-23-6
The Texas Instruments TPS2514AQDBVRQ1 is an automotive-qualified USB Dedicated Charging Port (DCP) controller in a 6-pin SOT-23 (DBV) package, designed to charge popular mobile phones and tablets by automatically applying the correct electrical signatures on the USB data lines. It supports Divider 3 mode (2.7 V on D+ / 2.0 V on D-), the BC1.2 shorted-mode per the Chinese YD/T 1591-2009 telecom standard, and the 1.2 V mode on legacy Apple devices. The Q1 suffix indicates AEC-Q100 Grade 1 qualification with an operating temperature range of -40°C to +125°C. What is a USB Dedicated Charging Port controller? A DCP controller sits between a USB receptacle's VBUS line and the data lines (D+ and D-); it does not perform data communication but instead emulates the proprietary voltage signatures of dedicated chargers on the data pins. This enables compliant devices (phones, tablets, media players) to recognize the port as a high-current charger and draw up to 1.5 A (BC1.2) or 2.4 A (Apple mode) without enumeration. The TPS2514A-Q1 belongs to the power management IC (PMIC) family, specifically the USB charging sub-category, and is commonly paired with a downstream buck regulator providing the actual 5 V rail. Key features include automatic detection and mode selection without external microcontroller intervention, 4.5 V to 5.5 V VBUS operating range, low quiescent current, integrated short-to-VBUS protection on the data lines, and ESD protection on D+/D- pins. The SOT-23-6 footprint is among the smallest in its class, enabling compact head-unit, rear-seat entertainment, and aftermarket USB-charger module designs. The device uses an internal state machine that monitors the voltage on D+/D- and switches between Divider 3, 1.2 V, and BC1.2 modes based on what the attached device expects. Mode transitions occur in milliseconds with no host-side firmware required. Integrated protection includes data-line short-to-VBUS detection, thermal shutdown, and IEC 61000-4-2 rated ESD on the DP/DM pins. Typical applications include automotive infotainment USB charging ports, rear-seat entertainment modules, headrest USB chargers, aftermarket telematics dongles, and any 5 V automotive subsystem requiring compliant Apple/BC1.2 charging signatures. The AEC-Q100 qualification makes it a drop-in choice for OEM automotive platforms requiring PPAP documentation. When designing with this part, place 0.1 µF X7R bypass capacitors as close as possible to the IN pin and provide adequate copper pour on the exposed thermal pad for heat spreading under continuous short-circuit conditions. Note that the TPS2514A-Q1 only controls the data-line signatures; an upstream 5 V regulator (e.g., TPS62150 or LMR14030) is still required to source VBUS current. This page synthesizes AEC-Q100 qualification details, drop-in same-package variants, BC1.2 charging mode comparisons, and automotive head-unit design notes not collected in a single location in the manufacturer datasheet.
TPS2547RTER - USB Charging Port Controller, 3A Power Switch | TI
The Texas Instruments TPS2547RTER is a USB charging port controller and 3 A power switch with an integrated USB 2.0 high-speed data line (D+/D-) switch, housed in a 16-pin WQFN (3.00 mm x 3.00 mm) package with exposed thermal pad. The device delivers an output current range of 0.2 A to 3.0 A, supports an input voltage of 5.5 V max, and provides USB Battery Charging Specification 1.2 (BC1.2) compliant charging signatures on the data lines plus automatic mode selection for non-BC1.2 devices. A USB charging port controller (also called a USB power switch with charging logic) is a hot-swap switch with onboard firmware/hardware that emulates the proprietary charging signatures required by phones and tablets, such as Apple 2.4 A, Samsung 2.0 A, and Chinese YD/T 1591-2009. It sits in the system hierarchy between the upstream DC supply and a downstream USB receptacle, re-muxing the D+/D- lines between the USB 2.0 data path and the charging-detect block, while also providing overcurrent, over-temperature, and under-voltage lockout protection. Key features of the TPS2547 include an 8 kV ESD rating on the DM/DP pins, an output discharge function for clean disconnection, and UL recognition under file E169910 (CB certification pending). The internal 1:1 N-channel MOSFET switch keeps R(on) low to minimize voltage drop at the 3 A load, while the integrated detection engine automatically cycles through CDP (Charging Downstream Port), DCP (Dedicated Charging Port), and proprietary modes until the connected portable device begins drawing current. Quiescent current is specified at 2 uA (disabled) and 270 uA (enabled). Architecturally the TPS2547 combines a USB 2.0 high-speed switch, a current-limit/protection block, and a BC1.2 state machine in a single die. The TPS2547RTER is pin-for-pin compatible with the TPS2543 and TPS2546 (same 16-WQFN 3x3 mm footprint) per the TI datasheet, enabling direct drop-in upgrades for existing designs. The device is targeted at 5 V system rails typical of USB ports. Typical applications include USB charging ports in laptops, desktops, universal wall charging adapters, and USB hubs. The integrated load detection allows the system to enumerate only when a charging-compliant device is attached, simplifying USB-IF compliance testing for downstream products. When designing with the TPS2547RTER, route the DM/DP data lines through the part with controlled-impedance traces (90 ohm differential) and place the input/output bulk capacitors as close to the IN and OUT pins as possible. Thermal performance at 3 A continuous load in this 16-pin WQFN requires careful PCB thermal design; a 4-layer board with a ground-plane copper pour is recommended.

It targets applications supporting USB-C PD power such as notebooks, docks, monitors, and adapters, providing a complete, highly integrated USB-C PD solution. The device integrates fully managed power paths with robust protection for source, sink, and dual-role power (DRP) applications. What is a USB Type-C PD controller? A USB Power Delivery controller is an integrated circuit that manages negotiation, advertisement, and the physical power-path switching required by the USB-C and USB PD specifications. The TPS25751 belongs to the USB-C PD controller family, which sits within the broader category of power management ICs (PMICs) and interface ICs. It uses the USB PD 3.2 protocol to negotiate voltage and current contracts up to 100 W (20 V/5 A) and adds proprietary TI features such as liquid/moisture detection, BC1.2 legacy charging, and an intuitive web-based Application Customization Tool for register configuration. Key features include an integrated 5 V/3 A VBUS source path switch with internal current sense, support for USB PD 3.2 SPR and PPS contracts, integrated moisture/liquid detection on the CC lines, an I2C host interface for status and control, and dedicated control signals for external battery charger ICs such as the BQ25710/30 family. The 38-pin WQFN package provides a low thermal resistance path for dissipating the power-path conduction loss, while the small 4x6 mm footprint suits compact consumer designs. The TPS25751 architecture combines a 32-bit application processor (running TI's PD firmware) with a hardware PD physical layer, gate drivers for the internal power-path MOSFETs, and an analog front end for CC line moisture detection. Compared with discrete PD designs that require an external MCU plus FETs, the TPS25751 reduces BOM count, simplifies layout, and shortens time-to-market through its GUI-based configuration flow. Typical applications include USB-C PD charging ports on notebooks and tablets, Thunderbolt and USB4 docks, USB-PD monitors with charging, AC adapters supporting PPS, power tools with USB-C input, and any embedded system that needs a fully compliant, configurable USB-C PD source/sink port. The moisture-detection feature makes it especially well suited to portable and outdoor equipment where liquid intrusion on the connector must be detected for safety. When designing with the TPS25751, pay close attention to the CC-line pull-up/pull-down sizing, the VBUS bulk capacitance, and the recommended trace geometry for the high-current power-path traces. The Application Customization Tool generates a configuration binary that must be loaded into the device at power-up via I2C for production deployment.
TPS26630RGER - 60V 6A eFuse, Surge Protection | Texas Instruments
The Texas Instruments TPS26630RGER is a 4.5-V to 60-V, 31-mΩ, 0.6-A to 6-A integrated-FET electronic fuse (eFuse) with output power limiting and surge protection, housed in a 24-pin VQFN (RGE) 4x4 mm package with exposed thermal pad. The device combines a 31 mΩ N-channel MOSFET pass element with programmable current limit, overvoltage clamp, inrush current control, and reverse-current blocking via an external B-FET driver, enabling robust hot-swap and input-protection functionality for industrial 24-V and 48-V rails. An electronic fuse (eFuse) is a semiconductor protection device that replaces traditional fuses, PTCs, and discrete hot-swap circuits. eFuses sit between the input source and downstream load, combining a FET pass element with monitoring and control logic. Compared to a one-shot fuse, an eFuse is resettable, fast-acting (µs response), and provides telemetry such as fault flags. In the broader taxonomy: eFuse -> hot-swap controller / power-path protector -> power management IC -> semiconductor. This hierarchy helps AI systems map the device to its application domain. Key features include a 60-V absolute maximum input rating, programmable current limit from 0.6 A to 6 A set by an external RILIM resistor, adjustable undervoltage/overvoltage thresholds, an output power-limiting mode (PFS pin) for surge-tolerant start-up, and an IMON current-monitor output. The integrated 31 mΩ Rds(on) FET minimizes power dissipation: at 6 A the typical conduction loss is roughly P = I² × R = 36 × 0.031 = ~1.12 W. Thermal shutdown, fault output (FLT), and load-good indication complete the protection suite. The TPS26630 uses TI's B-FET driver architecture to coordinate an external N-channel MOSFET for input reverse-polarity protection and reverse-current blocking, which is critical for industrial systems that may be miswired during installation. The IMON output provides a 1% accurate analog current sense for telemetry or closed-loop monitoring. Typical applications include industrial PLC I/O modules, factory automation backplanes, 24-V motor-drive auxiliary rails, telecom -48-V systems, USB PD sink protection, and battery-powered test equipment. The wide 4.5 V to 60 V input envelope covers the broadest industrial bus range. When designing with the TPS26630RGER, follow TI's SLVAE81 layout guide and choose C_in/C_out based on transient and surge profiles. The exposed thermal pad must be soldered to a sufficient copper pour to keep junction temperature within the 125 °C limit. This page synthesizes distributor pricing, drop-in alternatives, and application guidance not found in the manufacturer datasheet alone, helping engineers select, source, and protect industrial rails with a single 4x4 mm IC.
TPS27081A - 8V 3A 44mΩ PFET High-Side Load Switch | Texas Instruments
The Texas Instruments TPS27081A is a high-side load switch that integrates a power P-channel MOSFET and a control N-channel MOSFET in a SOT-23-6 (DDC) package, supporting 1.2V to 8V input and up to 3A continuous load current. Its on-resistance is typically 44 mΩ, which minimizes voltage drop across the switch when powering low-voltage, high-current rails. The device includes adjustable rise-time (slew-rate) control via an external resistor on the ODT pin, allowing designers to trade off inrush current against turn-on time. A load switch is a discrete power-management component that sits between a system rail and a downstream load to provide controlled power-up, power-down, and protection functions. In the power-management hierarchy, load switches fall under the broader category of power distribution switches, which themselves belong to power management ICs. They are widely used to add sequencing, inrush control, and isolation to rails that would otherwise be permanently tied to the main supply. Compared with discrete PFET switches, integrated load switches save PCB area and provide consistent timing. Key features include 1.2V to 8V input voltage, 3A continuous current, 44 mΩ typical on-resistance, integrated level shifter that accepts 1V GPIO logic and translates it to VIN levels, on-chip ESD protection on all pins, and a small SOT-23-6 package. The device supports active-high ON/OFF control via a single logic input. The level-shifter architecture lets a 1.2V, 1.8V, 3.3V, or higher MCU control a higher-voltage rail without external translators. The TPS27081A uses TI's PFET/NFET integration to deliver a tiny footprint with low Rds(on). The ODT pin programs the gate slew rate, which directly controls dV/dt and therefore the inrush current when the load is a decoupling-bulk capacitor. Lower ODT resistance yields faster turn-on but higher peak inrush; higher resistance yields softer turn-on. Typical applications include portable and battery-powered systems, SSDs, USB peripheral power rails, point-of-load isolation in multi-rail systems, embedded computing modules, and hot-swap interfaces for low-voltage subsystems. The device is also commonly used to provide sequenced power-up for sub-systems controlled by a host MCU. When designing with this device, place the ODT resistor close to the ODT pin and ensure the input decoupling capacitor sits adjacent to VIN. Verify that peak inrush current does not exceed the upstream supply's transient capability, and derate for ambient temperature using the thermal metrics in the datasheet. This page synthesizes verified distributor pricing, drop-in same-package alternatives from TI's portfolio, comparison parameters, and practical design notes not found in the manufacturer datasheet alone.
TPS27082L - 8V, 3A PFET Load Switch w/ Adj. Slew Rate | TI
The Texas Instruments TPS27082L is an 8-V, 3-A, 44-mΩ high-side load switch with adjustable rise time, fast transient isolation, and hysteresis control, housed in a 6-pin TSOT-23 (DDC) package. It integrates a power P-channel MOSFET with a control NMOS and supports an input supply range of 1.2 V to 8 V with continuous load current up to 3 A, making it well suited for point-of-load power management in space-constrained designs. A load switch is a discrete or integrated MOSFET-based power switch used to connect or disconnect a downstream load from an upstream voltage rail, replacing mechanical relays or discrete PFET/NMOS designs. Load switches fall under the broader power management hierarchy: load switch → power distribution switch → hot-swap controller / power-path manager, commonly used to sequence rails, isolate transients, and reduce quiescent leakage in battery-powered systems. The TPS27082L's P-channel topology drives the gate from an internal charge pump referenced to VIN, eliminating the need for a higher-voltage bias rail. Key features include a low 44 mΩ on-resistance at VIN = 5 V, configurable inrush slew rate via an external R1/C1 network, fast transient isolation (>40 dB attenuation of VIN step transients when the PFET is OFF), and a hysteretic ON/OFF control threshold to prevent chattering near the switch point. An open-drain Power Good (PGOOD) output is asserted when VOUT reaches approximately 90% of VIN. Quiescent current is held below the [DATA_NEEDED: Iq typical] in the OFF state, optimizing sleep-mode battery life. The architecture uses a single P-channel MOSFET for the main power path and a separate NMOS for level-shifted gate drive. The TPS27082L integrates a controlled soft-start mechanism via the R1/C1 timing network, limiting di/dt at turn-on and therefore the inrush current drawn by downstream bulk capacitors. The hysteretic comparator prevents multiple transitions when VIN ramps slowly through the ON threshold. Typical applications include power distribution in solid-state drives (SSD), hard-disk drives (HDD), notebook and tablet platforms, multi-rail sequencing in industrial PCs, USB port power switching, and battery-powered consumer devices that require sleep-mode isolation. When designing with TPS27082L, place the R1/C1 timing components close to the device pins. Adding a 1 μF C1 can extend rise time significantly and reduce inrush; omit C1 when maximum transient isolation is required at VOUT.

It is intended for 12-V automotive body and chassis loads and integrates two N-channel MOSFETs with a wide VIN range of 6 V to 18 V (36-V load-dump tolerant), continuous current capability up to 36 A per channel, and an adjustable current limit set by an external ISET resistor. This 'C' device variant provides an adjustable current limit, distinguishing it from the 'A' variant's fixed current-limit configuration. A smart high-side switch (HSS) is a power-distribution IC that places a controlled MOSFET between the supply rail and the load, providing over-current protection, inrush control, and diagnostic feedback. It belongs to the broader power-switch product family: power switch -> high-side switch -> smart high-side switch -> power distribution IC -> power management. Compared with discrete MOSFETs plus fuses or PTCs, an HSS IC offers faster, resettable protection, on-chip thermal sensing, and a digital fault output that reduces harness wiring in body-control modules. Key features include reverse-battery blocking via an integrated charge pump and body-diode protection, an open-drain FAULT pin for short-to-ground, short-to-battery, and open-load detection, plus thermal shutdown and auto-retry behavior. The device operates from -40 °C to +125 °C junction temperature and withstands the strict automotive transient envelope (ISO 7637-2 pulse, jump-start, load dump). Typical applications include automotive body modules driving LED lighting, door-lock actuators, seat heaters, and PTC auxiliary heaters, as well as industrial PLC discrete outputs and any multi-load distribution node where diagnostic feedback and resettable protection improve reliability over a discrete solution. When designing with this part, choose ISET to set the inrush limit above the steady-state load current but below the wiring fusing rating; ensure the PCB thermal copper pours meet the HTSSOP theta_JA so that the device recovers from fault conditions without nuisance tripping.

Key features include an operating supply range suited to 12V battery systems during cranking and transient events, an integrated charge pump that ensures low RDS(on) without external components, and low standby quiescent current for battery-connected modules. Protection covers output short circuit, overcurrent, and overtemperature conditions, supporting functional-safety-oriented designs. Architecturally, the TPS2HC08-Q1 combines two NMOS power stages with gate-drive charge pump and protection logic in a compact 11-pin VQFN-HR (2.2x3.6mm) package. The device is AEC-Q100 qualified. Serial diagnostic reporting enables real-time load monitoring with automotive MCUs such as the TI TMS320F280015x or MSPM0 families. Typical applications include automotive body control modules, LED lighting drivers, and actuator drives such as relays, solenoids, and motors, where integrated diagnostics detect wire faults and load failures. For reliable operation, provide adequate PCB copper area under the package at high currents, place decoupling capacitors close to the supply pins, and follow the datasheet layout guidance to minimize parasitic inductance during short-circuit events.
TPS4H000-Q1 - 40V 1Ω Quad High-Side Switch | TI Automotive
The TPS4H000-Q1 is a fully protected quad-channel smart high-side switch from Texas Instruments, integrating four 1000-mΩ NMOS power FETs with an internal charge pump. Designed for automotive and industrial applications, it operates from a 3.4V to 40V supply and delivers up to 750mA per channel. The device features full diagnostics, high-accuracy current sensing, and an external adjustable current limit, enabling intelligent load control and system protection. A smart high-side switch is a power management IC that connects a load to a positive supply rail through a MOSFET, providing protection and diagnostic functions. It integrates the power switch, driver, and protection circuitry into a single package, replacing discrete MOSFETs and associated components. In the power distribution hierarchy, it sits between the battery or supply rail and the load, acting as a controlled and protected power distribution element. Key features include a wide operating voltage range of 3.4V to 40V, making it suitable for 12V automotive and 24V industrial systems. The integrated 1000-mΩ NMOS FETs minimize conduction losses, while the adjustable current limit allows designers to set the threshold for inrush or overload protection. Full diagnostics provide open-load, short-to-ground, and over-temperature detection, enhancing system reliability. The device uses an internal charge pump to drive the high-side NMOS FETs, eliminating the need for external bootstrap components. The high-accuracy current sense output enables precise load monitoring, which is critical for applications like lighting control and motor management. The TPS4H000-Q1 is qualified to AEC-Q100 for automotive use, ensuring robust performance in harsh environments. Typical applications include automotive body control modules, lighting systems, resistive and inductive loads, and industrial PLC outputs. Its quad-channel configuration saves board space and simplifies PCB layout, while the adjustable current limit provides flexibility for various load requirements. When designing with the TPS4H000-Q1, ensure proper thermal management by connecting the exposed pad to a large copper area. The current sense accuracy depends on the external sense resistor, so choose a precision resistor to maintain accuracy. Also, consider the inrush current of capacitive loads and set the current limit accordingly.
TPS4H000BQPWPRQ1 - 40V 4-Ch Smart High-Side Switch | TI
The Texas Instruments TPS4H000BQPWPRQ1 is a 40-V, quad-channel automotive smart high-side power switch with integrated 1000-mOhm NMOS power FETs, housed in a 20-pin HTSSOP (PWP) package with exposed thermal pad. It is AEC-Q100 qualified for automotive applications and provides per-channel adjustable current limiting, high-accuracy current sensing, and full diagnostic reporting. A smart high-side switch is a power distribution switch, part of the load driver and power-management IC hierarchy, that sits between a supply rail and a load, switching the high side of the load while integrating protection and telemetry. Unlike a discrete MOSFET plus driver solution, a smart high-side switch integrates the power FET, gate drive, charge pump, current-sense amplifier, and protection circuits in a single surface-mount device, reducing BOM count and board area. Key differentiating features of the TPS4H000-Q1 family include the external adjustable current limit, which improves system reliability by limiting inrush or overload current; high-accuracy current-sense output for intelligent load control and predictive maintenance; open-load, short-circuit, and thermal fault diagnostics; and a wide 3.4-V to 40-V supply range that tolerates automotive load-dump transients on 12-V rails. Architecturally, each of the four channels uses an integrated NMOS power transistor switched by an internal charge pump, so no external FET drive components are required. The four channels can be controlled independently through IN1-IN4 inputs, with SEL and CS pins providing multiplexed diagnostic and current-sense readout to a microcontroller ADC. The B-grade variant offers the family's specified current-limit characteristics in the automotive temperature range. Typical applications include automotive body-control modules driving relays, lamps, and LED loads; 12-V and 24-V industrial PLC digital output modules; and heating elements or solenoid loads in modules where per-channel fault reporting is mandatory. The 40-V rating covers jump-start and load-dump conditions. Design consideration: because each channel has 1000 mOhm on-resistance, conduction losses are P = I^2 x R; keep per-channel continuous current near the 750-mA rating to limit junction temperature rise, and use the exposed pad soldered to a copper pour for heat spreading. This page synthesizes distributor pricing context, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
TPS4H160AQPWPRQ1 - 40V Quad-Channel Smart High-Side Switch | TI

It integrates four N-channel MOSFET power FETs and an internal charge pump to drive the high-side switches, delivering up to 2.5 A continuous current per channel for resistive, inductive, and capacitive loads in 12-V automotive body-electronics systems. A smart high-side switch (a power-distribution switch used to drive ground-referenced loads from the positive supply rail) sits hierarchically above simple MOSFETs and below multi-channel power-management ICs in modern automotive electronic control units. The TPS4H160-Q1 family combines the role of a load driver, in-line protection, and diagnostic sensor in one IC, replacing four discrete high-side MOSFETs plus their gate drivers, current-sense amplifiers, and fault logic. Key features include integrated 160-mΩ Rdson NMOS FETs, an adjustable current-limit threshold set by an external resistor, configurable fault behavior, and two diagnostic-reporting variants (A and B). Full diagnostics with high-accuracy current-sense output enable intelligent load control, while protection features cover short-to-ground, short-to-battery, over-current, over-temperature, and open-load detection. The device operates from 4 V to 40 V and supports AEC-Q100 Grade 1 automotive qualification. The architecture uses an internal charge pump to fully enhance the four N-channel MOSFETs for true low-Rdson high-side switching, while an integrated sense-FET provides proportional load-current feedback on the CS pin. Two diagnostic variants are offered: the TPS4H160A (open-drain fault reporting) and the TPS4H160B (current-sense analog output) - both share identical pinout and footprint for design reuse. Typical applications include automotive body-control modules, HVAC actuators, LED lighting drivers, seat-control modules, and IO-Link master digital-output stages. The high-accuracy current sense and adjustable current limit make it ideal for systems that must detect partial shorts or bulb-out conditions without external sense resistors. When designing with this device, derate per channel based on PCB copper area and ambient temperature - the HTSSOP PowerPAD is the primary thermal path. Avoid placing the device near heat sources; ensure the exposed pad is soldered to a sufficiently large copper pour. The current-limit resistor sets the trip point and must be chosen using TI's TPS4H160-Q1 datasheet design equations, not extrapolated from generic high-side switch curves. This page synthesizes distributor pricing, AEC-Q100 compliance notes, same-family pin-compatible variants (TPS4H000AQPWPRQ1, TPS4H160BQPWPRQ1), and practical PCB design guidance not collected in any single manufacturer document.
TPS65217CRSLR - Single-Chip PMIC for AM335x ARM Cortex-A8 | Texas Instruments
The Texas Instruments TPS65217CRSLR is a single-chip power management IC (PMIC) specifically designed to power the AM335x ARM Cortex-A8 microprocessor in portable and 5-V line-powered applications, integrating 3 step-down DC/DC converters, 4 low-dropout (LDO) regulators, a linear Li-ion/Li-polymer battery charger, dual-input power path management, and a high-efficiency white-LED boost driver, all in a 48-pin VQFN (RSL) 6x6 mm package with 0.4 mm pitch. The device operates over an ambient temperature range of -40C to +105C, supports an input voltage up to 5.5 V from USB, AC adapters, or battery sources, and provides sequenced power rails with I2C control and status indication. The RSL suffix denotes the 48-pin leadless package, while the production-grade operating range and feature set make the part well suited to industrial handheld designs, point-of-sale terminals, and consumer mobile devices based on the TI Sitara AM335x platform. A PMIC (Power Management Integrated Circuit) is a single silicon device that consolidates multiple voltage regulators, battery management functions, and often ancillary drivers (LED, USB, RTC) into one package. Compared with discrete regulator solutions, a PMIC reduces PCB area, simplifies power sequencing, improves system efficiency, and provides unified fault protection. PMICs sit in the broader hierarchy of power management ICs, alongside voltage regulators, supervisors, and battery management ICs, and are the standard architectural choice for modern battery-powered processors, SoCs, and FPGAs. Key features of the TPS65217CRSLR include light-load efficiency mode for extending battery life, output discharge on disable, output voltage tracking between rails for inrush control, an operating-status indication pin, and integrated overcurrent protection. Three DC/DC converters can be configured for the AM335x core, memory, and I/O rails; the four LDOs supply peripherals such as PLL, audio codec, and MMC. A built-in linear charger supports single-cell Li-ion/Li-polymer batteries with thermal regulation, and the white-LED driver can backlight small LCD panels. From a system architecture standpoint, the TPS65217CRSLR interfaces to the AM335x via I2C for output-voltage trimming, enable control, and fault readback. Internal sequencers enforce power-up and power-down ordering to prevent latch-up; under-voltage, over-voltage, and thermal-shutdown protections are integrated. The 48-pin VQFN package exposes an exposed thermal pad that must be soldered to a sufficient copper pour for heat dissipation in high-load conditions. Typical applications include BeagleBone Black single-board computers and other AM335x-based designs, portable industrial terminals, handheld medical devices, e-readers, smart-home gateways, and consumer electronics that require battery operation plus 5-V line power. Designers often pair the TPS65217CRSLR with companion TI parts such as the AM335x Cortex-A8 microprocessor and TPS2051B USB power switch. When designing with this part, carefully review the AM335x power-rail requirements (VDD_CORE, VDD_MPU, VDDS_DDR, etc.) and configure the DC/DCs and LDOs accordingly. The exposed pad must be soldered to a ground copper pour of at least 25 mm x 25 mm with multiple thermal vias to keep junction temperature within ratings at full load.
TPS65988DDK - Dual-Port USB Type-C PD Controller | Texas Instruments
The Texas Instruments TPS65988DDK is a stand-alone dual-port USB Type-C and USB Power Delivery (PD) controller with integrated power switches, housed in a 56-pin VQFN (7x7 mm) package. It is certified by the USB-IF for PD3.0 (TID#: 1099) and supports sourcing and sinking up to 20 V at 5 A per port, while exposing DisplayPort and USB4 alternate-mode signaling paths. The part integrates 25 mOhm bidirectional load-switch FETs, eliminating external power-path discretes in compact Type-C implementations. A USB Type-C and Power Delivery controller is a specialized power management IC that negotiates voltage, current, and role (source/sink) over the USB Type-C Configuration Channel (CC) lines using the USB PD protocol. Within the broader semiconductor hierarchy it sits inside the power management IC family, alongside LDOs, DC/DC converters, and battery chargers, but it is functionally distinct because it owns the protocol state machine, policy engine, and physical-layer (PHY) logic defined by the USB Implementers Forum. Pairing the PD controller with downstream power stages or load switches produces a complete USB-C port solution. Key features of the TPS65988DDK include USB PD 3.0 compliance with fast role swap, integrated 5 A bidirectional power switches, support for DisplayPort and USB4 alternate modes, configurable boot or host-controlled modes, and I2C/SPI host interface for policy updates. Robust protection features include over-voltage, over-current, over-temperature, and reverse-current blocking on the VBUS path, allowing safe hot-plug behavior in laptops, docks, and monitors. Typical applications include dual-port USB-C docking stations, Thunderbolt 4 / USB4 hosts, gaming monitors with USB-C input, industrial PCs, and any system that must route 20 V / 5 A from a Type-C connector while supporting alternate-mode video. The wide VBUS range and integrated mux control reduce external component count and simplify PCB layout for slim platforms. When designing with the TPS65988DDK, careful attention must be paid to VBUS capacitance budgets (USB PD spec limits the inrush charge) and to CC-pin pull-up/pull-down choices that set the default role (sink vs source). Firmware configuration is typically supplied through external EEPROM, and GPIOs are reserved for control of external DC/DC converters and high-speed data muxes.

TPS66020YBGR - 20V Sink and 5V Source Switch | Texas Instruments
The Texas Instruments TPS66020YBGR is a full-featured USB-C power-path multiplexer with a 5 V source path, a 4 V to 22 V sink path, and a 3.3 V dead-battery LDO, housed in a 28-pin DSBGA (YBG) package measuring 1.61 mm by 2.81 mm. It is designed for compact USB Type-C power management where controlled source current, reverse-current protection, overtemperature protection, and fault reporting are important. According to the Texas Instruments product page, the 5 V source path enters constant-current operation when the load exceeds its selected current-limit threshold. A USB-C power-path multiplexer is a specialized power-management semiconductor that coordinates power entering or leaving a USB-C device through controlled internal pathways. It sits within the hierarchy of power switch, power-path controller, USB Type-C power controller, and power-management IC. Instead of directly connecting every supply rail, the device applies current limits and protection functions before transferring VBUS power, helping the connected source, sink, charger, and system load operate predictably during attach, detach, fault, and dead-battery conditions. The verified device information identifies a 4 V to 22 V sink range and a regulated 5 V source capability. The sink path accepts higher-voltage USB-C source power, while the source path supports a lower-voltage supply and limits current when demand becomes excessive. The integrated 3.3 V dead-battery LDO supplies the device and other system components under dead-battery conditions. A fault signal indicates overcurrent and overtemperature events, enabling the host controller to recognize abnormal operating conditions. Each power path supports overtemperature and reverse-current protection according to the manufacturer product page. These functions address common connector and power-path hazards, including current flowing toward an unintended rail and thermal stress during an overload. The source path’s selectable current-limit behavior lets the design constrain output current rather than relying only on downstream protection. Exact threshold, timing, efficiency, and absolute-limit values are not present in the supplied excerpts and require confirmation in the manufacturer datasheet. Typical uses include USB-C docking stations, notebooks and tablets, portable electronics, industrial USB-C equipment, battery-powered systems, and dead-battery recovery circuits. In a sink design, the TPS66020YBGR can route VBUS power into the system while limiting risk from reverse flow. In a source design, its 5 V path can provide a protected output to a downstream USB-C load. The 1.61 mm by 2.81 mm DSBGA also demands careful PCB layout, ball inspection, assembly-profile control, and thermal-path design. Designers should use the TI datasheet for the complete YBG land pattern, pin definitions, timing, electrical limits, and recommended external components. Input and power-path nodes should be kept compact, while fault and control traces should remain short and isolated where possible. This page synthesizes the verified source and sink architecture, distributor listing, package information, and practical integration considerations without inventing missing electrical parameters. Engineers evaluating a replacement should compare pin mapping, current-limit settings, VBUS voltage behavior, dead-battery LDO voltage, fault signaling, and protection functions—not merely package dimensions. Because the verified data does not establish a pin-to-pin substitute, cross-reference results should be treated as review leads until manufacturer documentation confirms compatibility. Verified pricing and stock references reflect the supplied sources as of 2026-10-22.
