TLE9201SGAUMA1 - 6A H-Bridge Motor Driver | Infineon | PG-DSO-12-17
The Infineon TLE9201SGAUMA1 is a 6 A H-bridge driver IC designed for the control of DC motors and other inductive loads in automotive applications, housed in a PG-DSO-12-17 (12-pin exposed-pad SOIC) package. It integrates two half-bridge MOSFET outputs with RDS(on) < 100 mOhm per switch, supports an operating voltage range of 5.0 V to 28 V, and offers fully 3.3 V / 5.5 V compatible logic inputs. PWM/DIR control reduces the number of PWM-capable pins needed on the microcontroller side, and outputs can be pulse-width modulated at frequencies up to 20 kHz with a current limitation threshold of 8 A. An H-bridge (full bridge) motor driver is a type of integrated power stage that uses four switching elements arranged in an H topology to drive a bidirectional DC load (such as a brushed DC motor) from a single supply rail. H-bridge drivers belong to the broader category of motor drivers and motion-control ICs, which in turn fall under power management semiconductors used to interface low-power microcontrollers with high-current electromechanical actuators. By integrating the power FETs, gate drivers, and protection logic into a single IC, the TLE9201SGAUMA1 replaces discrete MOSFET bridges and significantly reduces PCB area and design complexity. Key features include short-circuit protection, over-temperature shutdown, low standby current, SPI-configurable diagnostics, and AEC-Q100 qualification for automotive use. The device also supports load currents above the current limitation threshold (8 A) by entering a fold-back / hiccup mode rather than latching off, allowing sustained fault handling in harsh environments. The TLE9201SGAUMA1 uses an N-channel MOSFET output stage with charge-pump gate drive, enabling low RDS(on) and high efficiency at low VIN. SPI diagnostics provide real-time feedback on fault conditions such as open load, short to battery, short to ground, and over-temperature. The integrated dead-time generation prevents cross-conduction of the high-side and low-side FETs during switching transitions, a critical reliability feature for H-bridge designs. Typical applications include throttle body control, HVAC flaps, mirror adjustment, headlight leveling, and small DC pumps in vehicles, as well as industrial valves, power tools, building automation, and small medical pumps. Any 12 V or 24 V brushed DC motor up to 6 A continuous current is a suitable load for this driver. When designing with this device, ensure that the exposed thermal pad (pin 12) is soldered to a sufficient copper area (at least 1 square inch on a 2-layer board) to keep junction temperature within SOA limits. Place the supply bypass capacitors (typically 100 nF ceramic plus 10 uF bulk) as close as possible to the VBB pin to suppress the high di/dt transients typical of PWM motor switching.

TLE9241QUXUMA1 - 7-Channel Solenoid Gate Driver IC | Infineon
The Infineon TLE9241QUXUMA1 is a 7-channel constant-current solenoid gate driver IC designed for automatic transmission control, integrating six low-side and one high-side driver channels with 8 Hall-effect sensor interfaces and an SPI communication port. Housed in a 48-pin PG-TQFP-48-9 package, it operates across a 4.5 V to 5.5 V logic supply range with a separate high-voltage VBAT domain and a peak load current capability of up to 7.5 A per channel, making it purpose-built for hydraulic solenoid valves in modern automatic transmissions. A solenoid driver IC is a specialized mixed-signal semiconductor that translates digital commands from a transmission control unit (TCU) into precisely regulated analog currents flowing through inductive loads such as pressure-control valves, shift valves, and lock-up clutches. As a category, it sits within the broader power-management IC (PMIC) hierarchy: gate driver -> solenoid driver -> motor/actuator driver -> PMIC -> semiconductor. By replacing discrete PWM drive circuitry and analog current-sense op-amps with a single highly integrated IC, the TLE9241 family dramatically reduces PCB area and improves diagnostic coverage in transmission ECUs. Key features of the TLE9241QUXUMA1 include integrated closed-loop current regulation via internal PWM generation, parallel SPI control of multiple devices for multi-valve TCU scaling, comprehensive fault diagnostics (open-load, short-to-ground, short-to-battery, over-temperature), and an operating temperature range of -40 °C to +150 °C suitable for under-hood automotive environments. The 7.5 A peak current capability per channel supports the high forces required by proportional pressure-control valves during gear shifts. Typical end applications are 6-, 7-, 8-, and 9-speed automatic transmissions (DCT, AT, CVT, e-clutch), electro-mechanical power steering (EMPS) actuation where similar proportional solenoid control is used, and dual-clutch module valve bodies. The Infineon TLE9241QU datasheet documents the SPI register map, dither/waveform control, and EMC behavior relevant for these transmission modules. When designing with the TLE9241QUXUMA1, allocate a 100 nF decoupling capacitor directly on each VS pin and a 10 µF bulk reservoir near the package, plus an exposed-pad thermal land for heat spreading during sustained PWM operation. The SPI bus must be pulled up to the logic VIO rail and protected with TVS diodes for harness transients exceeding ISO 7637-2. This page synthesizes current distributor stock levels, parametric drop-in alternatives, SPI register guidance, and EMC layout considerations that go beyond the manufacturer datasheet, giving transmission engineers a single point of reference for sourcing and design-in.

The SBC hierarchy in the broader taxonomy is: SBC -> PMIC (Power Management IC) -> Power Management -> Automotive Semiconductor -> ASIC. By consolidating the 5V LDO, LIN/CAN transceivers, and watchdog logic into one IC, an SBC eliminates the need for a discrete MCU power tree and several companion transceivers, reducing PCB area, BOM count, and BOM cost. Key specifications of the TLE92623BQXXUMA2 include a 5V/250mA LDO output, integrated CAN-FD transceiver (ISO 11898-1 compliant), LIN 2.x transceiver, integrated window watchdog, and SPI control interface. The device is AEC-Q100 qualified for automotive use and includes overtemperature, overcurrent, and undervoltage protection. Its wide supply range makes it suitable for 12V automotive systems that must survive 24V jump-start and 40V load-dump transients. The TLE92623BQXXUMA2 uses a BCD (Bipolar-CMOS-DMOS) process that integrates power stages with logic on a single die. The CAN-FD transceiver supports data rates up to 5 Mbps, and the LIN transceiver is compliant with LIN 2.2A. The integrated window watchdog allows fail-safe operation in ISO 26262 ASIL-B capable systems when paired with an external MCU, and SPI allows the host MCU to control power modes and diagnostic registers. Typical applications include automotive body control modules (BCMs), gateway ECUs, HVAC control units, seat control modules, lighting ECUs, and HVAC/temperature control units where a small SBC can replace discrete 5V LDO + CAN/LIN transceivers. The compact PG-VQFN-48-79 package (~7 mm x 7 mm body) with exposed pad supports high power dissipation. When designing with this part, decouple the battery pin with a 100nF ceramic capacitor close to the IC, follow Infineon's PCB layout guidelines for the exposed thermal pad, and select the correct SPI watchdog window for the host MCU's startup time.

The IC operates from a 5.5V to 20V supply range and is part of Infineon's TLE94xyz DC motor driver family, delivering integrated multi half-bridge functionality with built-in protection features. According to Infineon datasheet materials, each half-bridge uses DMOS output stages capable of driving brushed DC motors, solenoids, relays, and lamp loads in automotive and industrial environments. A DC motor driver (also called a motor driver IC or half-bridge driver) is a power-management semiconductor that sits between a low-power microcontroller and a high-current motor load. Within the power-management IC hierarchy, the TLE94003EPXUMA1 belongs to the broader category of motor drivers > motion controllers > integrated power switches. By integrating three half-bridges, one chip can drive a single three-phase brushless DC (BLDC) motor, three independent brushed DC motors, or be paralleled into full-bridge configurations for higher-current brushed motors. Key features include 5.5V to 20V supply range, integrated charge pump allowing 100% duty-cycle operation, ultra-low quiescent current in standby, built-in over-current, over-temperature, under-voltage, and short-circuit protection, plus a diagnostic feedback pin. The DMOS output stages are optimized for low on-resistance, which directly minimizes conduction losses and improves thermal performance. The PG-TSDSO-14 package with exposed thermal pad enables efficient heat dissipation in space-constrained automotive modules. Typical applications include automotive body electronics (HVAC flaps, mirror adjustment, seat positioning), industrial automation (small brushed and brushless DC motors, valve control), and consumer appliances. The integrated protection set eliminates the need for many external components, simplifying PCB layout and reducing BOM cost. When designing with this part, observe the exposed-pad PCB layout recommendations: solder the thermal pad to a copper pour of at least 1 cm² for proper heat removal. Use decoupling capacitors rated for the full supply transient range, and configure the SPI/EN/diagnostic pins per the datasheet's typical application circuit to ensure correct fault propagation.

TLE94104EP - Quad Half-Bridge Motor Driver, 5.5-20V | Infineon
The Infineon TLE94104EP is a protected quad half-bridge driver with integrated N-channel MOSFET output stages, designed for automotive motion control such as HVAC flap DC motors. It delivers up to 0.9 A continuous per channel (depending on configuration) from a 5.5 V to 20 V supply in a 24-pin SSOPGA package with exposed thermal pad. An automotive-grade half-bridge driver IC is a power-management building block that combines multiple low-side/high-side MOSFET half-bridges with logic-level control, gate drivers, charge pump, and diagnostic feedback. The TLE94104EP belongs to the TLE94xyz family of multi-half-bridge drivers - a category that sits between discrete H-bridge MOSFET designs and fully integrated BLDC FET drivers. It abstracts the low-level power-stage design, giving the MCU a clean digital interface (SPI or direct-input) instead of bootstrap-capacitor and gate-timing concerns. The TLE94104EP combines four half-bridge output stages that can be configured as 1, 2, 3, 4, 5, or 6 independent half-bridges for parallel high-current loads. The device accepts either a 16-bit SPI command set or direct-input logic pins for control and diagnosis, with adjustable open-load thresholds on two outputs. The integrated charge pump and 5.5 V to 20 V supply range cover the full automotive 12 V bus envelope (including load-dump transients handled externally). Typical automotive applications include HVAC flap and blend-door motors, headlight beam leveling, small grille shutters, and other low-power brushed DC loads that previously required a discrete H-bridge plus protection circuitry. Pairing the TLE94104EP with an automotive MCU such as the Infineon TLE9844 or AURIX family lets designers replace 8-12 discrete MOSFETs, gate drivers, and protection parts with one IC, reducing PCB area by typically 60%. A key design consideration is reverse-polarity protection - the TLE94104EP datasheet requires an external reverse-battery FET because the internal free-wheeling diodes will conduct during reverse polarity, causing reverse current from ground. Also ensure the exposed thermal pad receives adequate copper pour to keep junction temperature within limits when driving high-current loads continuously.

The Infineon TLE94104EPXUMA1 is a protected quad half-bridge driver IC designed for automotive DC motor control, integrating four half-bridge output stages with on-board power MOSFETs and 16-bit SPI control in a 14-pin PG-TSDSO-EP (exposed-pad) surface-mount package. The device operates from a 3 V to 5.5 V logic supply and 5.5 V to 20 V motor supply, driving up to four external low-side switches or acting as a fully integrated 4-channel half-bridge driver for DC motors, solenoids, and relays. Each output stage is rated for continuous DC motor current with built-in over-temperature, over-current, and short-circuit protection, and the part is qualified to -40 C to +150 C junction temperature per automotive grade-0 requirements. What is a half-bridge motor driver? A half-bridge driver is a power-conversion building block that switches one terminal of a load (typically a DC motor winding) between a high-side supply rail and a low-side ground rail. Four half-bridges can be paralleled or paired into two full H-bridges, giving flexible bidirectional control of up to four DC motors or two stepper-motor windings. The TLE94104EP belongs to Infineon's TLE94xyz integrated multi half-bridge family, which trades the flexibility of discrete MOSFET gate drivers for the simplicity, diagnostic coverage, and PCB-area savings of an integrated solution. Key features include per-channel current limiting, open-load detection in OFF state, configurable slew-rate control, and global charge-pump generated gate drive for the high-side N-channel MOSFETs. The 16-bit SPI interface provides daisy-chain capability for up to 16 devices on a single bus, allowing scalable actuator counts in body-control modules. Internal thermal shutdown with hysteresis protects the IC from junction over-temperature faults and reports status back to the host MCU through the SPI status register. Typical applications include Heating, Ventilation and Air Conditioning (HVAC) flap control, electronic seat adjustment, mirror folding, sunroof drives, and other low-to-medium current brushed DC loads in 12 V automotive body networks. The wide operating-voltage range also supports industrial 24 V systems with adequate derating, and the small PG-TSDSO-14 package with exposed thermal pad enables compact PCB layouts under the dashboard. When designing with the TLE94104EPXUMA1, ensure the exposed pad is soldered to a copper area of at least 1 cm squared to keep the junction within the safe operating area at maximum motor current. Place the logic supply (VCC) decoupling capacitor as close as possible to the IC pins to prevent logic-level noise from corrupting SPI transactions.

The Infineon TLE94110ESXUMA1 is a 10-fold half-bridge driver IC for DC motor control, housed in a 24-pin PG-TSDSO-24 exposed-pad package. It supports a supply voltage range of 5.5V to 20V, integrates ten 1.5A (typical) MOSFET half-bridge outputs, and provides a 16-bit SPI plus direct-input (DI) control interface with comprehensive diagnostic feedback. According to the Infineon product page, the device can be configured as 3, 4, 6, 8, 10, or 12 half-bridges by paralleling outputs, giving PCB designers flexibility when driving mixed loads. A half-bridge (H-bridge) motor driver is a power-converter topology that uses MOSFET half-bridges in push-pull configuration to drive DC loads bidirectionally. The TLE94110ES family sits in the motor-driver hierarchy as follows: motor driver -> half-bridge driver -> power management IC -> semiconductor. Compared with discrete MOSFET half-bridges, integrated multi-half-bridge drivers reduce PCB area, simplify thermal design by spreading dissipation across the exposed pad, and embed critical protection features such as overcurrent, open-load, and overtemperature shutdown. Key features include 1.5A continuous output current per channel (up to 2A peak, depending on configuration), integrated PWM generators with adjustable dead time, open-load detection with programmable threshold on two outputs, and full short-circuit, overtemperature, and undervoltage protection. The 16-bit SPI daisy-chain capability allows multiple TLE94110ES devices to be controlled from a single MCU, supporting up to 12 half-bridges per chip and beyond via cascade. The device is built on Infineon's smart power technology, combining DMOS output stages with CMOS logic on a single die. The exposed thermal pad provides a low thermal-resistance path to the PCB copper, enabling sustained 1.5A operation across all ten outputs simultaneously with proper board design. The wide 5.5V-20V input range covers 12V automotive bus systems including cranking transients when the input is buffered. Typical applications include HVAC flap motors in automotive climate control, small DC and brushless DC (BLDC) motor driver stages, LED lighting modules with per-string current control, and generic multi-channel solenoid/relay drivers. Its 10-channel density makes it especially attractive for zonal body-control modules replacing discrete relay boxes. When designing with this part, observe the exposed-pad PCB layout guidelines: use at least 6 cm² of copper on top and bottom layers with thermal vias to spread heat from all 10 channels. Configure unused outputs as open-drain or tie them to the supply through a pull-up, and always enable the open-load detection on critical safety loads. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, giving engineers a single, citation-ready reference for automotive multi-motor control designs.
TLE94112ESXUMA1 - 12-Fold Half-Bridge DC Motor Driver | Infineon
The Infineon TLE94112ESXUMA1 is a protected twelve-fold half-bridge driver designed for automotive motion-control applications, packaged in a PG-TSDSO-24 (exposed-pad) surface-mount housing. Each of the twelve half-bridge outputs can source/sink up to approximately 0.9 A continuous, and the outputs are freely configurable into parallel, half-bridge, or full-bridge topologies, making the part a single-chip solution for multi-motor DC loads. A serial peripheral interface (SPI) provides output control, diagnostics, and daisy-chain capability for up to sixteen devices. What is a multi half-bridge driver? It is a power-management IC that integrates multiple low-side/high-side FET half-bridges into a single package, replacing discrete H-bridge MOSFET assemblies. Within the broader taxonomy, the TLE94112ESXUMA1 sits as: half-bridge driver -> full/half-bridge driver -> motor driver -> power management IC -> semiconductor. Other members of Infineon's TLE94xyz family span 3 to 12 outputs and offer either direct PWM inputs or SPI control. Key features include per-channel current limiting, over-temperature shutdown, open-load detection, and short-circuit protection to ground or supply. The wide supply range supports 5.5 V to 18 V operation (with load-dump tolerance up to 40 V typical for 12 V automotive systems), and the exposed thermal pad of the PG-TSDSO-24 package provides a low-resistance path to PCB copper for heatsinking. SPI daisy-chaining reduces microcontroller GPIO count when controlling multiple drivers in a vehicle. Typical applications span HVAC flap DC motors, seat-adjustment modules, window lift and sunroof drives, mirror adjusters, and other small brushed-DC loads in body-electronics modules. The integrated protection set reduces external component count and improves functional safety metrics when paired with a host MCU. A design consideration is that even though the TLE94112ESXUMA1 is highly integrated, paralleling outputs to achieve higher continuous current still requires careful thermal layout - the PG-TSDSO-24 EP must be soldered to a sufficiently large copper area to keep junction temperature within the -40 C to +150 C operating range. Always close an input bulk capacitor near the VS pin to absorb load-dump transients.

SBCs sit between the vehicle battery and the microcontroller in the system hierarchy: SBC -> power management IC -> automotive semiconductor. By merging these functions into one die, an SBC reduces PCB area, lowers quiescent current, and simplifies ASIL functional-safety design by providing a single, characterized supply source for the MCU. Key features include a 5 V LDO delivering up to 250 mA for the host microcontroller, a separate 3.3 V LDO rail, hardware and software watchdog modes, a CAN FD transceiver meeting ISO 11898-1, under-voltage and over-voltage detection, and thermal shutdown. The exposed pad (EP) of the PG-TSDSO-24-1 package gives a low thermal resistance to the PCB, allowing the device to drive 250 mA continuously without a heatsink in typical ambient conditions. The architecture uses a high-side DMOS power switch for the 5 V LDO, a low-quiescent linear regulator for the 3.3 V rail, and a differential CAN transceiver compliant with ISO 11898-2. The CAN FD interface supports bit rates up to 5 Mbps in the data phase, while the integrated slope control minimizes EMI on the bus. Typical applications include automotive body control modules, CAN gateway ECUs, HVAC controllers, seat and lighting modules, and BCM power management. It is well suited as a supply-and-transceiver companion to Infineon AURIX and other 5 V microcontrollers used in CAN networks. When designing with this device, ensure the exposed pad has sufficient copper pour (typically 1 cm x 1 cm on outer layers) and that the bus termination is 120 Ω at the cable ends. Use Infineon’s configuration tool to set watchdog timing, fail-safe behavior, and wake sources before firmware bring-up.

The Infineon TLE94713ESV33XUMA1 is a Lite System Basis Chip (Lite SBC) from the OPTIREG SYS BASICS family, integrating a 5 V main LDO regulator, a second 5 V off-board-protected sensor supply LDO, a 5 Mbps HS-CAN FD transceiver, and an SPI configuration/status interface in a single PG-TSDSO-24-1 package for automotive body and powertrain networks. It targets CAN-FD body controllers, gateways, and sensor-cluster nodes where one IC must supply a microcontroller, sensor rails, and a robust CAN bus interface while minimizing PCB area. What is a Lite SBC? An SBC (System Basis Chip) is a power-management-plus-communication IC that combines multiple functional blocks (LDOs, DC-DC, transceivers, watchdog, wake logic) into one automotive-qualified device. A 'Lite' SBC strips out the DC-DC and most wake logic to deliver the minimum functions at the lowest cost. The TLE9471-3ES sits in the OPTIREG SYS BASICS hierarchy: SBC -> Lite SBC -> single-LDO SBC -> HS-CAN-FD variant. Key features include the 5 V/200 mA main microcontroller LDO with input voltage up to 28 V (load-dump tolerant), an additional 5 V/100 mA LDO with off-board (sensor short-to-battery/ground) protection for sensor supply, a 5 Mbps CAN-FD transceiver compliant with ISO 11898-1:2015, and a 16-bit SPI for diagnostics and control. The PG-TSDSO-24-1 (TSSOP-24 EP) package provides an exposed pad for thermal dissipation of the internal linear regulators. Typical applications include CAN-FD body-domain ECUs (lighting, door, seat modules), sensor cluster nodes, gateway peripherals, and 12 V automotive subsystems. The dual 5 V LDO architecture removes the need for two external regulators, and the integrated transceiver eliminates a discrete CAN PHY, BOM cost, and PCB area. When designing with this part, ensure the input supply is reverse-battery protected upstream (the device tolerates load dump but not continuous reverse polarity). Provide sufficient copper on the exposed pad to keep the main LDO within its SOA at 200 mA continuous load. Use the SPI to mask unused wake sources and to configure the watchdog window.

A motor System Basis Chip (SBC) combines what traditionally required several discrete components: the gate-driving power stage for a motor, the local power supply for a microcontroller, and the vehicle network transceiver. In the automotive electronics hierarchy, the TLE9560-3QX family sits between a standalone pre-driver and a full power SoC, providing a single-chip solution for brushless DC (BLDC) motor control nodes. Key features include multiple integrated half-bridges that drive the external power stage of a 3-phase BLDC motor, an on-chip 5 V regulator that supplies the attached microcontroller, and dual communication interfaces (CAN FD and LIN) that connect the node to the vehicle body or powertrain network. The SPI interface allows the host MCU to configure diagnostics, protection thresholds, and PWM control parameters. Technically, the device targets 28 V automotive board-net systems. Integrated protection and diagnostic functions - including current sensing support and fault reporting via SPI - reduce external component count and support functional-safety-oriented designs. The exposed-pad PG-VQFN-48 power package provides the thermal path needed for sustained motor-drive operation. Typical applications include automotive BLDC pumps (water, fuel, oil), HVAC blowers and fans, window lifters, and other body-domain motor loads requiring CAN/LIN connectivity. The integrated 5 V regulator eliminates a separate LDO for the MCU. Design consideration: provide adequate PCB copper area under the exposed pad to extract heat from the half-bridge power stage, and follow Infineon layout recommendations for the power and ground returns.

It delivers integrated half-bridge MOSFET outputs with 18 µA typical quiescent current and supports operating junction temperatures from -40 °C to +150 °C, targeting 12V/24V automotive body and powertrain applications. A BLDC motor driver is a power-management and gate-driver IC that converts low-power logic commands from an MCU into the high-current phase-drive waveforms (PWM, commutation) required by three-phase brushless DC motors. In the broader taxonomy it sits under motor drivers and motion controllers, itself a sub-category of power management ICs and gate drivers. Highly-integrated multi-half-bridge parts such as the TLE9561 family further combine supply generation (LDO, charge pump) and communication transceivers (CAN, LIN, SPI), allowing one IC to replace several discrete blocks on a compact ECU PCB. Key differentiating features of the TLE95613QXXUMA1 include four half-bridge outputs (extendable to six via external drivers), integrated short-circuit and over-temperature protection, an SPI control port for diagnostics and PWM generation, and an exposed thermal pad for direct PCB heat-sinking. The wide 5.5V to 28V supply range suits both 12V and 24V automotive bus rails, while built-in charge-pump support enables 100% duty-cycle drive of the N-channel MOSFET half-bridges. The architecture uses an NMOS output stage with adaptive dead-time control, an internal charge pump for high-side gate drive, and a 5V LDO plus 3.3V tracker to supply the host MCU. Diagnostic features include open-load detection, short-to-battery and short-to-ground reporting per output, and a thermal warning/shutdown chain that protects both the IC and the motor winding. Typical applications include automotive HVAC blowers, engine cooling fans, electric water pumps, seat ventilation, and other 12V/24V BLDC or DC motor loads. Designers frequently pair the TLE95613 with Infineon Aurix or AURIX TC2xx/TC3xx MCUs and TLE925x CAN transceivers to form a complete motor-control ECU. Design considerations include providing adequate PCB copper area beneath the exposed pad for thermal dissipation, respecting the max supply rating of 28V including load-dump transients, and using the SPI watchdog to bring outputs into a safe state on MCU loss-of-clock. The high-side gate drive relies on the integrated charge pump, so the external reservoir capacitor value must follow the datasheet recommendation. This page synthesizes distributor pricing, pin-compatible same-family Infineon alternatives (TLE9561-1QX, TLE9561-2QX, TLE9561-4QX variants), and practical design guidance that goes beyond the datasheet summary, including thermal analysis and EMI considerations specific to the PG-VQFN-48-31 exposed-pad footprint.

A motor driver IC is an integrated circuit that combines gate drivers, power MOSFETs, protection circuits, and a digital control interface (typically SPI) into a single package. Motor drivers sit at the bottom of the power-management hierarchy: BLDC driver IC -> motor driver -> power management IC -> semiconductor. By integrating the half-bridge stages and a 5V/3.3V supply, the TLE9561QX eliminates the need for separate gate-driver ICs and external LDO regulators in compact mechatronic modules.

At the architecture level, the device combines an ARM-compatible embedded power controller with high-side and low-side charge-pump-driven N-channel MOSFET outputs. The SPI interface allows parametrization of current limits, dead times, slew rates, and diagnostic thresholds. Thermal shutdown, overcurrent, open-load, and short-to-ground/battery diagnostics are multiplexed back to the microcontroller through the same SPI bus, enabling predictive maintenance. Typical applications include HVAC blowers, engine cooling fans, water/oil pumps, e-compressors, electric power steering (EPS) auxiliary drives, and any small three-phase BLDC actuator in a 12V automotive board net. The wide Vin range also supports 24V mild-hybrid subsystems. When designing with this device, ensure that the exposed pad is soldered to a sufficient copper area for thermal dissipation. Use the SPI watchdog to detect microcontroller lockups and place the decoupling capacitors as close as possible to the supply pins to suppress switching noise.

Key features include NMOS half-bridge power outputs driving brushed DC motors, an integrated CAN interface, an integrated LIN interface, PWM motor control, and SPI for configuration and diagnostics. Single-package integration reduces bill-of-material count, PCB area, and system cost while enabling comprehensive on-chip protection and diagnostic functions typical of Infineon automotive motor drivers. Technically, the device belongs to Infineon's Embedded Power family of motor system ICs, which combines digital control logic and power silicon with galvanic isolation-free monolithic integration. The NMOS output stage topology delivers efficient motor drive with low on-state conduction losses, while the SPI interface exposes status, fault, and configuration registers to the host system. Integrated power-on reset, watchdog, and supply monitoring functions support functional-safety-oriented architectures. Typical applications include HVAC blower motor control, engine compartment pump and valve actuators, powered liftgates, window lifters, and other brushed DC motor actuators in 12V automotive board nets. The CAN and LIN interfaces make the part suitable for both gateway-connected and low-cost networked actuator nodes. Design consideration: because the device integrates the power stage, PCB thermal design around the PG-VQFN-48-31 exposed pad is critical - the layout should provide adequate copper area and via stitching under the exposed pad to conduct motor winding and conduction losses into the board.

TLF11251EPXUMA1 - 2.5A Half-Bridge Gate Driver | Infineon
The Infineon TLF11251EPXUMA1 is an integrated half-bridge gate driver capable of sourcing/sinking 2.5 A, designed for OPTIREG PMIC TLF35584/85 pairing with AURIX TC38x/TC39x 32-bit microcontrollers. Housed in a 14-pin PG-TSDSO-14-5 package, the device drives a PMOS/NMOS output stage with non-inverting logic and a wide 2.35 V to 7 V supply input. The combination of 60 ns typical propagation delay and 2.5 A peak drive makes it the companion driver for the core voltage rails of high-end 2nd-generation TriCore AURIX microcontrollers. A half-bridge gate driver is a power-management building block that combines a high-side and a low-side MOSFET driver in one IC, translating low-current PWM logic signals from a controller into the high-current gate drive required to switch power MOSFETs or, in this case, a PMOS/NMOS bridge. Within the broader IC taxonomy, this places the part in the gate-driver sub-family of power management ICs, itself a subset of PMIC and analog mixed-signal semiconductors. Half-bridge drivers are commonly used as core-supply pre-regulators or post-regulators next to multi-rail PMICs. Key features include 2.5 A peak gate-drive current, 60 ns propagation delay, non-inverting input logic, and 2.35 V to 7 V supply operation. The PG-TSDSO-14-5 thermally-enhanced small-outline package provides a low thermal resistance path for the high peak currents encountered during MOSFET switching transitions, while the non-inverting interface simplifies PWM routing from the host controller. Internally, the TLF11251EP combines a PMOS high-side path and an NMOS low-side path with adaptive drive strength and protection features. The 2.5 A capability allows it to switch large PMOS/NMOS bridges quickly, reducing switching losses and improving transient response on the AURIX core supply rail. The OPTIREG product family designation confirms Infineon qualification for safety-relevant automotive power architectures. Typical applications include AURIX TC38x/TC39x core supply pre-regulation, OPTIREG TLF35584/85 PMIC companion drivers, automotive 12 V ECU power trees, and industrial 24 V buck/boost pre-drivers. The wide supply range and high drive strength also make it suitable as a general-purpose PMOS/NMOS half-bridge in 5 V and 12 V distributed power systems. When designing with this device, observe the absolute maximum supply rating of 7 V and provide a local 100 nF + 1 µF decoupling network directly at the VCC pin. Keep the gate-drive traces short and width-matched to limit parasitic inductance, which can otherwise cause ringing on the PMOS/NMOS gate that may violate the AURIX core supply tolerance window.
TLF11251LDXUMA1 - 2.5A Half-Bridge Gate Driver for AURIX | Infineon
The Infineon TLF11251LDXUMA1 is a 2.5 A half-bridge gate driver IC housed in a 10-pin PG-TSON-10-2 (exposed pad) package, designed as a companion driver for the OPTIREG PMIC TLF35584/85 in automotive ECU power architectures. The part uses a PMOS/NMOS output stage that delivers 2.5 A peak source/sink current with 60 ns typical rise and fall times, enabling fast switching of power MOSFETs in 12 V automotive battery rails. A half-bridge gate driver is a power-management IC that translates low-current logic-level PWM signals from a microcontroller into the high-current gate-drive signals required to switch the high-side and low-side MOSFETs of a synchronous buck or boost converter. In the broader power-management hierarchy, the TLF11251 sits between the microcontroller (control layer) and the discrete power MOSFETs (switching layer), making it a critical glue device in DC-DC converter sub-systems. Without a dedicated driver, a microcontroller GPIO pin cannot directly charge and discharge a power MOSFET gate fast enough for efficient high-frequency switching. Key specifications include a 3.5 V to 7 V supply range, 2.5 A peak output drive, 60 ns propagation delay matching between high-side and low-side channels, and integrated shoot-through protection that prevents both MOSFETs from conducting simultaneously. The non-inverting input logic simplifies PWM signal routing, and the exposed thermal pad keeps junction temperature low during continuous switching. The driver is qualified to AEC-Q100 for automotive under-hood and chassis applications. The TLF11251 is specifically engineered to pair with Infineon's AURIX TC38x and TC39x 32-bit TriCore microcontrollers, providing the gate-drive stage for downstream buck converters that power the MCU core, ADC, and communication peripherals. The tight propagation-delay matching supports the dead-time control required by the OPTIREG TLF35584/85 PMIC family. Internal shoot-through protection and under-voltage lockout (UVLO) on the driver supply safeguard the power stage during cold-crank and load-dump transients typical of 12 V automotive electrical systems. Typical applications include 12 V automotive DC-DC converters, AURIX TC38x/TC39x ECU power stages, body-control modules, ADAS sensor power rails, and industrial 24 V buck regulators. The 2.5 A drive strength is sufficient for switching most sub-100 V N-channel MOSFETs commonly used in point-of-load converters up to approximately 10 A load. When designing with this part, place the bootstrap capacitor for the high-side channel as close as possible to the BST and SW pins to minimize switching losses. The exposed pad must be soldered to a sufficiently large copper pour to keep junction temperature within the -40 C to +125 C automotive grade-A operating range. This page synthesizes distributor pricing, parametric comparisons, and practical PCB-layout guidance not collected in a single Infineon document.

The Infineon TLF12501AUMA1 is an automotive AEC-Q100 integrated power stage co-packaging a synchronous buck gate-driver IC with control and synchronous MOSFETs, delivering 60A continuous output current (up to 90A peak) in a 36-pin PQFN 5x6 mm package. The device operates from a 4.25V to 16V input rail, supports switching frequencies up to 2000 kHz, and integrates a low quiescent-current driver optimized for high-efficiency point-of-load conversion. What is an integrated power stage? An integrated power stage is a semiconductor building block that combines the high-side FET, low-side FET, and gate driver into a single co-packaged IC, placed next to a buck controller IC in multiphase or high-current VR topologies. Within the power management hierarchy, power stages sit one level below the voltage regulator controller and one level above discrete MOSFETs, reducing parasitic loop inductance, shrinking PCB area, and simplifying thermal design compared with discrete implementations. Key features of the TLF12501AUMA1 include AEC-Q100 automotive qualification, integrated bootstrap FET, adaptive dead-time control, tri-state PWM input compatibility, and a current-sense output for telemetry. The PQFN 5x6 package exposes a top-side thermal pad delivering a junction-to-PCB thermal resistance suitable for 60A continuous airflow-cooled designs. The driver's optimized gate timing and internal Schottky-diode clamping minimize switch-node ringing when layout guidelines are followed. Architecturally, the TLF12501 uses Infineon's OptiMOS power-MOSFET technology co-packaged with a low-IQ driver core. The driver accepts 3.3V tri-state PWM logic from external controllers such as the IR35215, XDPE132G5C, or IR3581. Internal adaptive dead-time circuitry prevents shoot-through while minimizing body-diode conduction loss. The exposed top pad and bottom-side leads maximize heat extraction directly into the PCB copper. Typical applications include server/datacenter VR buck converters, telecommunications 48V-to-point-of-load stages, automotive ADAS power rails, graphics card and GPU core voltage regulators, and high-current ASIC/FPGA POL supplies. The AEC-Q100 qualification makes it well suited for automotive ECU power trees requiring 60-90A peak transient capability. When designing with this device, allocate a 4-layer PCB with at least 2 oz copper on top/bottom layers directly under the thermal pad. Place input capacitors within 2 mm of the VIN/PGND pins to suppress switch-node overshoot. Keep the BOOT capacitor trace short to limit rise-time losses. Source-sink current handling is symmetric, so the part is suitable for bidirectional telemetry and POL applications requiring fast transient response.
TLF1963TEATMA1 - 1.5A Adj LDO Regulator, 340mV Dropout | Infineon
The Infineon TLF1963TEATMA1 is a 1.5 A adjustable low-dropout (LDO) linear voltage regulator housed in a 5-pin PG-TO252-5-13 (TO-252/DPAK) surface-mount package. The output is adjustable from 1.21 V to 19.66 V, with a typical dropout of 340 mV at full 1.5 A load, and the device accepts input voltages up to 20 V. It is qualified for automotive applications and operates across a -40 °C to +150 °C junction temperature range. An LDO (Low-Dropout) linear regulator is a type of voltage regulator that maintains a stable output voltage even when the input-to-output voltage differential is small, in contrast to classical NPN regulators that require at least 2 V headroom. Within the broader taxonomy, LDOs sit below switching regulators (DC-DC converters) in efficiency but excel in noise performance because they do not switch. The TLF1963TEATMA1 belongs to the Infineon linear regulator family -> voltage regulator family -> power management IC category, targeting noise-sensitive and space-constrained loads where a switching converter's EMI would be unacceptable. Key features include a positive adjustable output from 1.21 V to 19.66 V, 1.5 A continuous output current, 340 mV typical dropout, and integrated protection functions such as current limiting and thermal shutdown. The device is supplied in a TO-252-5 (DPAK) package with an exposed thermal tab that doubles as the main heat-dissipation path and as pin 5 (TAB/GND). The "TE" suffix denotes the TO-252-5 package, while "ATMA1" denotes a 13-inch Tape & Reel packing orientation used in high-volume automotive assembly. Technically, the regulator uses a PNP pass element architecture that enables low-dropout operation but carries a quiescent current that flows to ground proportional to load. The reference is trimmed to 1.21 V typical, and the output is set by an external resistor divider according to VOUT = 1.21 V x (1 + R1/R2). The output capacitor ESR range is specified in the manufacturer datasheet to maintain loop stability - typically a low-ESR ceramic or tantalum of 22 µF or greater is recommended. Typical applications include automotive body and chassis ECUs, sensor supplies (5 V rails for Hall/pressure sensors), point-of-load regulation downstream of a 12 V automotive bus, and industrial 24 V to lower-voltage conversion. Designers frequently use the TLF1963 for micro-controller and CAN-transceiver supplies where post-regulation noise is critical. Compared to a switching converter, the TLF1963 trades efficiency for low EMI and simple BOM, making it ideal when the load is below 1.5 A and the input-to-output drop is modest. When designing with this part, ensure that the maximum power dissipation does not exceed the thermal capability of the DPAK land pattern - copper-pour area on the PCB tab is the primary heatsink. Place input and output capacitors close to the IC and respect the ESR window required by the control loop. Always verify the regulated output voltage spec under worst-case combinations of VIN and IOUT as stated in the manufacturer datasheet.

Typical applications are ADAS domain controllers, chassis ECUs, electric power steering, and body controllers that require functional safety up to ASIL-D. The device is qualified to AEC-Q100 grade 1 and supports ambient operating temperatures from -40C to +150C junction. When designing with the TLF35584, engineers must observe Infineon's reference layout for the LQFP-64 thermal pad and follow the application note guidance on SPI configuration for window watchdog timing.

TLF35584QVHS2XUMA1 - ASIL-D PMIC | Infineon | OPTIREG
The Infineon TLF35584QVHS2XUMA1 is a multi-rail functional-safety Power Management IC (PMIC) from the OPTIREG family, integrating an ASIL-D-compliant voltage regulator architecture for automotive microcontrollers (e.g., AURIX TC3xx). Per the Infineon datasheet for the TLF35584 family, it operates from a wide 3.0 V to 40 V input supply (transient tolerant), provides up to eight regulated output rails, and is housed in a 48-pin PG-VQFN-48 (7 mm x 7 mm) exposed-pad package rated for the harsh automotive Grade 0 / -40 to +175 °C junction temperature window. An automotive safety PMIC is a highly integrated DC/DC and LDO regulator system designed to deliver deterministic, monitored power rails to safety-critical microcontrollers. PMICs belong to the broader power-management semiconductor category, alongside discrete DC-DC converters, LDOs, and battery management ICs. The TLF35584 family specifically targets ISO 26262 ASIL-D functional safety requirements, embedding window watchdog, error pin monitoring, fail-safe output state machine, and configurable reset behavior. Key features include a primary step-down (buck) regulator for the microcontroller core, two auxiliary buck converters, a 5 V / 3.3 V LDO, a tracker/supply for off-board sensors, an SPI/parallel configuration interface, independent safety state machine, ABIST (logic BIST), and LBIST (ADC BIST) support, plus a dedicated error output to the host MCU. The wide 3.0 V to 40 V input range tolerates cranking transients and load-dump events on the automotive 12 V bus. Architecturally the device combines synchronous buck converters, low-dropout regulators, and an integrated spread-spectrum oscillator to minimize EMI, while dedicated safety logic supervises undervoltage, overvoltage, watchdog timing, and thermal conditions. The exposed thermal pad and Grade 0 qualification allow direct placement near the microcontroller in safety-critical ECUs without secondary heatsinking. Typical applications include AURIX TC3xx safety microcontrollers in electric power steering (EPS), airbag ECUs, ADAS domain controllers, brake controllers, and electrified powertrain ECUs. For multi-rail safety systems, the TLF35584 simplifies board design by replacing four to six discrete regulators and external supervisors with a single ASIL-D-capable IC. When designing with this device, follow Infineon's recommended input bulk/ceramic capacitor network, observe SPI pull-up conventions, and verify the fail-safe state machine configuration with the TLF35584 safety manual. The error output pin must be routed to a host MCU interrupt for ASIL-D compliance.
TLF42772ELXUMA2 - 300mA 40V LDO w/ Current Monitor | Infineon
The Infineon TLF42772ELXUMA2 is a monolithic low-dropout (LDO) linear voltage regulator with an integrated current monitor, housed in a 14-pin PG-SSOP-14-EP package with exposed thermal pad. It delivers up to 300 mA of output current over an adjustable output range of 5 V to 12 V, accepting input voltages up to 40 V. The IC is engineered as the ideal companion supply for active antennas in automotive infotainment systems. An LDO (Low-Dropout) linear regulator is a type of voltage regulator that maintains a stable output voltage even when the input-to-output differential is small. LDOs sit within the broader linear regulator hierarchy, which itself belongs to the power management IC family and ultimately to power semiconductor components. The LDO's defining characteristic is that, unlike a switching regulator, it dissipates excess voltage as heat but adds no switching noise to the output - making it the preferred topology for noise-sensitive analog and RF rails. Key features of the TLF42772ELXUMA2 include a 40 V maximum input rating (well suited for direct connection to automotive 12 V or 24 V buses with load-dump transients), an integrated current-monitor output that mirrors the load current for diagnostics, and built-in protection for overvoltage, overtemperature, and overcurrent conditions. The adjustable output is set by an external resistor divider, and the device includes a reset/wake function for ECU sleep/wake coordination. The device uses a bipolar pass element architecture to achieve the 40 V input tolerance required by 12 V automotive systems. The integrated current monitor is implemented as an analog mirror sourced through a dedicated pin, eliminating the need for an external shunt resistor in antenna-fault-diagnostic applications and reducing BOM cost and PCB area. Compared with discrete regulator-plus-shunt designs, the TLF42772ELXUMA2 cuts component count while meeting AEC-Q100 automotive stress-test standards. Typical applications include active-antenna power supply in car infotainment head units, GPS/SDARS antenna modules, telematics control units (TCUs), and body-domain controllers requiring a clean 5 V to 12 V rail from a noisy 12 V battery feed. It also suits industrial sensor conditioning and any 12 V/24 V industrial bus that needs a regulated low-current rail with load monitoring. When designing with this part, place input/output ceramic capacitors close to the IC pins and ensure the exposed pad is soldered to a sufficient copper pour for thermal dissipation. The current-monitor pin output must be scaled with an external resistor to match the host ADC's input range, and the reset delay capacitor value should be chosen to satisfy the downstream microcontroller's power-good timing requirement.

TLF44773LAXUMA1 - 300mA LDO 3-20V Adj | Infineon OPTIREG
The Infineon TLF44773LAXUMA1 is an OPTIREG linear low-dropout (LDO) voltage regulator delivering up to 300 mA of output current from a positive adjustable output, supplied from a 3 V to 20 V input rail. It comes in a 14-pin PG-TSON package with an exposed pad for thermal relief and ships on tape and reel. The combination of wide input range, low dropout, and integrated protection features targets always-on automotive and industrial rails. An LDO (Low-Dropout) linear regulator is a type of linear voltage regulator that can maintain a stable output voltage even when the input-to-output differential (dropout) is only a few hundred millivolts. Within the power management hierarchy, LDOs sit below switching converters (DC-DC) as the final clean-up stage - they trade efficiency for ultra-low noise, fast transient response, and minimal external component count. The TLF44773LAXUMA1 belongs to Infineon's OPTIREG linear family, which is designed for harsh electrical environments and includes comprehensive protection and diagnostic features. Key features of the TLF44773LAXUMA1 include the 3 V to 20 V input operating range, a positive adjustable output (set by an external resistor divider), 300 mA continuous load capability, low quiescent current suitable for permanently powered nodes, and an integrated reset/watchdog function for microcontroller supervision. The PG-TSON-14-3 exposed-pad package provides a low thermal resistance path, supporting sustained 300 mA output without external heatsinking in typical automotive supply designs. Architecturally, the regulator combines a precision bandgap reference, an error amplifier, and a low-RDS(on) P-channel pass element to achieve low dropout and clean regulation. On-die protection includes current limit, thermal shutdown, reverse-polarity robustness (a hallmark of OPTIREG parts), and short-circuit foldback. The reset output and watchdog logic interface directly with automotive microcontrollers, enabling the LDO to replace a discrete supervisor IC in cost- and space-sensitive ECU designs. Typical applications include automotive body and chassis ECUs, sensor supply rails, dashboard and infotainment microcontrollers, industrial PLC and HMI controllers, and battery-connected (KL30/permanent) supplies in 12 V vehicles. The device is qualified for automotive use, making it suitable for designs that must operate reliably across wide temperature and supply transients such as load-dump and cold-crank events. When designing with this part, place input and output ceramic capacitors close to the IC pins, route the exposed pad to a sufficiently large copper pour (the thermal pad is the dominant heat path at 300 mA), and ensure the resistor divider uses 1% tolerance resistors to maintain output accuracy. If the load sits far from the regulator, add a small feedforward capacitor across the top feedback resistor to improve transient response.
