BTS711L1XUMA1 - 4-Ch 1.7A Smart High-Side Switch | Infineon
The Infineon BTS711L1XUMA1 is a 4-channel smart high-side power switch rated 1.7 A per channel (4.5 V to 28 V operating range), housed in a PG-DSO-20-31 package with an exposed thermal pad for enhanced heat dissipation. It integrates four N-channel vertical power FETs with built-in protection, diagnostic feedback, and 43 V load-dump overvoltage clamping for harsh 12 V automotive environments. A high-side power switch is a type of intelligent semiconductor switch that connects a load to the positive supply rail and provides embedded protection, diagnostics, and PWM capability. These devices sit within the broader power management hierarchy: high-side switch → load switch → power distribution switch → power management IC → semiconductor. Compared with discrete MOSFETs and fuses, a multi-channel smart high-side switch dramatically reduces PCB area, simplifies wiring harness design, and replaces electromechanical relays with a fully solid-state solution. Key specifications include a 1.7 A nominal per-channel load current, 4.5 V to 28 V operating supply range, 43 V overvoltage clamp, R_DS(on) of approximately 200 mΩ per channel, very low standby current, and dedicated current sense / status feedback. Integrated features include overload protection, active current limiting, short-circuit protection, thermal shutdown with auto-restart, overvoltage protection including load-dump, fast demagnetization of inductive loads, reverse-battery protection (with external R_GND), and ESD robustness per automotive EMC requirements. The BTS711L1 belongs to Infineon's Classic PROFET™ 12 V family. It uses a vertical DMOS process and incorporates charge-pump driven N-channel MOSFETs that achieve true low-R_DS(on) on the high side. Each channel is independently protected and diagnosable, supporting both resistive and inductive loads (valves, solenoids, lamps) commonly found in body-control modules. The PG-DSO-20-31 exposed-pad package provides a low thermal resistance path so the device can sustain short high-current transients without immediate shutdown. Typical applications include automotive body electronics (door modules, mirror folding, seat control), lighting control (interior LED strings, exterior lamps), 12 V relay and solenoid replacement, industrial PLC outputs, and any multi-load distribution node requiring diagnostic feedback. When designing with this device, ensure R_GND is correctly sized (2 × 150 Ω or 1 × 75 Ω per the datasheet) for reverse-battery protection and clean current-sense accuracy.
BTS71202EPGXUMA1 - 2-Ch 2A Smart High-Side Switch | Infineon
The Infineon BTS71202EPGXUMA1 is a dual-channel, 110 mΩ N-channel high-side power switch belonging to the PROFET™ +12V smart-switch family, housed in a 14-pin PG-TSDSO-14 exposed-pad package. Each of its two independent channels is rated for 2 A continuous load current, operates from a 3.1 V to 28 V supply (Vbb), and is controlled by an active-high CMOS-compatible input. Per-channel diagnostics include a current-sense (IS) pin and built-in protection against overload, short-circuit, over-temperature, over-voltage, and reverse battery conditions. A high-side switch is a power-MOSFET driver topology where the load is tied to ground and the switch sits between the positive supply rail and the load. Compared with low-side switches, high-side drivers simplify wiring harnesses, eliminate ground-shift issues, and integrate easily into automotive body-control modules where chassis ground returns are long and noisy. The BTS71202 sits inside the broader PROFET family of protected switches (which are part of Infineon's power-management IC portfolio) and is a member of the 12 V automotive smart-switch category. Key features of the BTS71202 include 110 mΩ typical on-resistance per channel at room temperature, very low standby current (~0.5 µA typ), integrated clamping for inductive loads, AEC-Q100 qualification, and a SPI-compatible diagnostic feedback path via the IS pin. Its PROFET +12V heritage means the device meets the stringent ISO 7637 transient, jump-start (36 V), and reverse-battery (–16 V) requirements common on vehicle 12 V buses. Architecturally, each channel stacks an N-channel power MOSFET with a charge pump and gate driver, plus analog current-sense and digital protection logic. The current-sense output delivers a current proportional to the load current, allowing the host MCU to detect open-load, short-to-ground, and over-current conditions without a discrete shunt resistor. Typical applications include automotive body-control modules, LED driver modules, relay and solenoid replacement, distributed power-distribution nodes, and general-purpose 12 V high-side switching in industrial systems. Compared with electromechanical relays, the BTS71202 offers smaller PCB area, no contact bounce, silent operation, and embedded diagnostics, while maintaining comparable current-handling capability. When designing with the BTS71202, place the device close to the load connector to minimize inductance in the high-current path, and reserve copper area for thermal dissipation since two channels can deliver a combined 4 A continuous in still air. A 100 nF X7R decoupling capacitor must be placed within a few millimetres of the Vbb pin to handle ISO 7637 transient pulses. This page combines distributor pricing, validated drop-in alternatives, and practical design considerations that go beyond the manufacturer's datasheet, helping procurement and engineering teams make faster, better-informed sourcing decisions.
BTS712204ESAXUMA1 - 4-Ch 5A SPOC Smart Switch | Infineon
The Infineon BTS712204ESAXUMA1 is a 4-channel smart high-side power switch (SPOC family) delivering 3A source / 5A sink per channel in a 24-pin PG-TSDSO exposed-pad package. It integrates four independently-controlled 200 mΩ RDS(on) channels with built-in protection, current limiting, and 24-bit SPI status diagnostics for automotive and industrial loads. What is a SPOC smart power switch? SPOC (Smart Power On Chip) is Infineon's family of multi-channel intelligent high-side switches that combine MOSFET output stages, gate drivers, protection logic, and digital diagnostics in a single monolithic die. SPOC devices sit hierarchically under the broader category of smart power switches -> power distribution ICs -> power management ICs -> semiconductor ICs. They are designed to replace discrete MOSFETs + fuses + relays by providing configurable overcurrent, overtemperature, open-load, and short-to-ground/short-to-battery protection, plus per-channel current readback via SPI. Key features include 4.0V to 28V operating supply range (load dump tolerant to 35V), 5 MHz SPI control interface, 80 µA quiescent current, 5A current-limit threshold, integrated reverse-battery protection with self-diagnostics, and AEC-Q100 Grade 1 automotive qualification. The PG-TSDSO-24 EP package exposes the die thermal pad directly to the PCB, enabling 4-layer FR-4 dissipation up to ~2W without external heatsinking. The BTS712204ESAXUMA1 uses a vertical N-channel DMOS output stage driven by a charge pump and SPI-configurable control logic. Each channel is independently protected against overcurrent (5A typ), overtemperature (165 °C typ shutdown), and load-dump transients. The SPI diagnostics block reads back per-channel current via a 24-bit sigma-delta ADC, enabling predictive load monitoring - a major advantage over conventional high-side switches that only report fault flags. Typical applications include automotive body control modules (BCM), LED matrix drivers, HVAC blower and valve control, distributed ECU loads, and industrial 24V solenoid/relay multiplexing. The 4-channel density in one package reduces PCB footprint versus discrete MOSFET solutions by approximately 60 percent. When designing, place the exposed pad on at least 4 thermal vias to a 1oz inner-layer copper pour to meet the AEC-Q100 thermal derating curve. Use TVS diodes (e.g. Infineon SMBJ) on VBB for ISO 7637-2 transient immunity beyond the integrated 35V load-dump clamp.

BTS712204ESEXUMA1 - 4-Channel 5A Smart High-Side Switch | Infineon
The Infineon BTS712204ESEXUMA1 is a 4-channel, 5 A intelligent high-side power switch belonging to Infineon's SPOC family of multi-channel smart switches. Housed in a 24-pin PG-TSDSO exposed-pad surface-mount package, each of the four outputs can deliver up to 5 A continuously and integrates comprehensive protection, diagnostic feedback, and a serial control interface. A smart high-side switch (also called an intelligent power switch or IPS) is a semiconductor relay that replaces mechanical relays, fuses, and discrete MOSFETs by placing one or more protected N-channel MOSFETs on the high side of a load. The SPOC family adds SPI-configurable current limits, load-dump robustness, reverse-battery protection, and per-channel fault telemetry, dramatically simplifying automotive and industrial body-electronics wiring harnesses while improving diagnostic coverage. Key features of the BTS712204ESEXUMA1 include 4 independent channels each rated to 5 A nominal (typical on-state resistance around 30 mOhm per channel), a 5 MHz capable serial diagnostic interface, very low standby current, integrated reverse-battery protection, load-dump robustness beyond 40 V, and per-channel current-limit / over-temperature / open-load detection. The AEC-Q100 qualification makes it suitable for automotive body-control modules, while the PG-TSDSO-24 EP package provides a thermal pad that reduces junction-to-ambient thermal resistance. Architecturally, the BTS712204ESEXUMA1 combines four vertical N-channel power MOSFETs, charge-pump gate drivers for true high-side operation, a digital SPI/diagnostic engine, and protection comparators on a single die. Because each channel shares package-level thermal mass, parallel operation of two or more channels increases total system current capability but must respect the package's total power-dissipation budget. Typical applications include automotive body-control units (door modules, seat control, lighting, mirror fold), LED driver modules (front and rear lamp loads), industrial PLC discrete outputs, and 12 V / 24 V load switching in commercial vehicles. When designing, ensure the EP thermal pad is soldered to a sufficient copper pour to keep junction temperature within ratings, and always place a reverse-battery protection diode or use the device's built-in reverse-battery capability on the supply rail.

BTS72002EPAXUMA1 - Dual 1.2A Smart High-Side Switch | Infineon
The Infineon BTS72002EPAXUMA1 is a dual-channel smart high-side power switch delivering 2x 1.2 A continuous output current per channel, housed in a 14-pin PG-TSDSO-14 exposed-pad package. It is part of Infineon's PROFET+2 family and is integrated in SMART7 technology, providing integrated protection and diagnosis functions. The on-state resistance per channel is 66.5 mOhm (typical) and both channels can be paralleled for higher load capability. A high-side power switch (also called a smart high-side driver or PROFET - Protected MOSFET) is a semiconductor device that sits between the supply rail and the load. It replaces a discrete MOSFET plus fuse plus protection circuitry by integrating an N-channel power MOSFET with reverse polarity, over-current, over-voltage, over-temperature, and short-circuit protection, plus diagnostic feedback to the microcontroller. In the broader taxonomy it sits under: power switch -> load driver -> power management IC -> semiconductor. The PROFET+2 family specifically targets automotive 12 V and 24 V body and chassis applications where reliability and diagnostic coverage are mandatory. Key features include a 0.8 V to 1.2 A adjustable current limit, 6 V to 18 V (extended 28 V) operating voltage, very low standby current, AEC-Q100 qualification, and digital status feedback. The 14-pin TSDSO with exposed thermal pad yields a junction-to-ambient thermal resistance around 35 C/W on a standard 2s2p board, allowing sustained 1.2 A per channel without external heatsinking in most body-controller layouts. The device integrates two N-channel MOSFETs in SMART7 process technology with charge pump, gate driver, current sense, and protective comparators. The diagnostic interface reports open-load, short-to-ground, short-to-battery, and over-temperature conditions via the IS pin to the host MCU, simplifying ASIL-rated ECU designs. Typical applications include automotive body control modules, LED lighting drivers, heating element switches (seat heaters, mirror heaters), and small motor drivers. The wide operating range also makes it suitable for 24 V truck and bus systems where reverse-battery robustness is required. When designing with this device, ensure the IS diagnostic pin is connected to an ADC input for fault monitoring and use the exposed pad as the primary heatsinking path. The PROFET+2 family is compatible with the hardest reverse-battery requirement on the market (down to -28 V), simplifying load protection on the supply rail. This page synthesizes distributor pricing, drop-in alternatives within the PROFET+2 family, and practical design notes not found in the manufacturer datasheet.
BTS72004EPAXUMA1 - 4-Ch 1A Smart High-Side Switch | Infineon
The Infineon BTS72004EPAXUMA1 is a 4-channel smart high-side power switch belonging to the PROFET+ 12V family, rated for 1 A per channel with an on-state resistance of 66.5 mOhm per channel and housed in a PG-TSDSO-14 package with exposed pad. It operates from a 6 V to 18 V supply range and integrates four independent N-channel MOSFET outputs with 1:1 switch/driver topology, designed primarily for automotive 12 V load driving. A smart high-side switch is a type of power distribution switch (load driver) that sits between the battery/rail and the load. When the controlling MCU asserts the channel input, the internal MOSFET turns on and connects the load to the supply. PROFET+ 12V devices add digital diagnostics, current limiting, and protection - in the system hierarchy they sit between a discrete MOSFET (lowest integration) and a fully-integrated multi-channel PMIC (highest integration), giving automotive ECUs a compact, fault-aware alternative to discrete relay/fuse solutions. Key features include active-high inputs for each channel, integrated overcurrent protection (OCP), overvoltage clamp, undervoltage protection (UVP), thermal shutdown, and proportional load-current feedback through the IS pin for diagnosis. The exposed pad of the TSDSO-14 package reduces thermal resistance, supporting continuous 1 A per channel operation at ambient temperatures up to 150 C junction. AEC-Q100 qualification makes it suitable for under-the-hood and body-control modules. Architecturally, each channel is built on Infineon's vertical N-channel DMOS process with charge-pump gate drive, allowing true low-Rdson switching from logic-level inputs. The device is designed to survive the harsh automotive 12 V environment, including load-dump transients up to 35 V, jump-start conditions, and reverse-battery events with external protection. Diagnostic current sense output (IS) provides a ground-referenced analog current mirror output proportional to each active channel's load current. Typical applications include automotive body control modules (driving lamps, LEDs, relays), power seat and mirror modules, HVAC flap motors, and decentralized front/rear lighting nodes. The four channels are commonly used in parallel with PWM for dimming or in independent configuration for mixed-load systems. Compared with discrete MOSFETs plus fuses, the BTS72004EPAXUMA1 reduces PCB area and adds self-protection that simplifies ECU design. When designing with this part, ensure adequate copper area on the exposed pad to keep junction temperature within limits; at 1 A per channel and full 4-channel operation, total power dissipation can approach 1 W. The IS pin requires a reference resistor and external ADC; choose sense resistor value to match the MCU ADC range for maximum diagnostic resolution. Use TVS diodes on Vbb for load-dump protection beyond the device's internal clamp.

BTS722204ESPXUMA1 - 4-Ch SPI High-Side Switch | Infineon
The Infineon BTS722204ESPXUMA1 is a SPOC +2 multichannel high-side power switch with four N-channel MOSFET outputs rated at 4 A, 4 A, 7 A and 7 A, housed in a PG-TSDSO-24-32 exposed-pad package. It integrates an SPI (Serial Peripheral Interface) for digital diagnostics and daisy-chain control, together with on-resistance values as low as 5.5 mOhm and 13.5 mOhm per channel, achieving low power dissipation in automotive 12 V wiring harnesses. The device is qualified for harsh automotive electrical environments and is part of the SMART7 family of protected high-side switches. Background: A high-side power switch (also called a smart high-side switch, semiconductor relay, or solid-state fuse) is a power-management semiconductor that sits between the battery/load supply and the load, replacing a discrete MOSFET plus fuse plus relay combination. Programmable logic-level inputs (here, 3.3 V and 5 V compatible) turn the channels on; integrated protection handles overcurrent, overtemperature, short-circuit, reverse battery and ground-loss events. High-side switches belong to the broader hierarchy: power switch -> load driver -> power management IC -> semiconductor. Key features of the BTS722204ESPXUMA1 include daisy-chain capable SPI for multi-device addressing, slew-rate control for electromagnetic-compatibility tuning, ReverseON operation that keeps the channels conducting during reverse polarity (low power dissipation in that mode), programmable restart after overcurrent, and absolute/dynamic temperature limitation with controlled restart. The SPI also reports open-load, short-to-ground and short-to-battery diagnostics per channel. Architecturally, each channel is built around an N-channel vertical power MOSFET driven by a charge pump, with the SPI block handling configuration, fault flags and daisy-chain pass-through. Channels 0/1 are rated 4 A (lower RDS(on) region of about 13.5 mOhm) and channels 2/3 are rated 7 A (RDS(on) about 5.5 mOhm), giving designers flexibility to pair heavier loads (H-bridge half-bridges, pumps) with lighter loads (lamps, LEDs) on one IC. Typical applications include body-control modules, front and rear lighting, seat-control and mirror-adjust loads, HVAC blowers, and any 12 V automotive load requiring protected switching with diagnostic feedback. Use the BTS722204ESPXUMA1 when you need per-channel current telemetry, low quiescent current in standby, and AEC-Q100-grade robustness in a small PG-TSDSO-24-32 footprint. Design consideration: because the device is SPI-controlled, the host microcontroller must reserve one SPI peripheral and three GPIO pins (CS, SCLK, SDO); for multi-IC harnesses enable the daisy-chain mode to share one CS line. Decoupling, ground returns and thermal copper area under the exposed pad are critical for sustaining the 7 A channels.

BTS723GWXUMA1 - 2.5A Dual High-Side PROFET Switch | Infineon
The Infineon BTS723GWXUMA1 is a 24 V dual-channel, smart high-side power switch from the Classic PROFET™ family, integrating two N-channel vertical power FETs with embedded protection and diagnostic functions in a PG-DSO-14-37 (14-pin DSO) package. Each channel is rated at 2.5 A continuous load current with very low standby current, CMOS-compatible logic inputs, and improved electromagnetic compatibility (EMC) for harsh automotive environments. A high-side power switch is a type of power distribution switch that connects a load (such as a lamp, solenoid, or motor) to the positive supply rail while the low-side of the load remains at chassis ground. It belongs to the broader category of power management ICs (PMICs), specifically the load driver / smart switch sub-category. Compared to a discrete MOSFET plus fuse arrangement, a smart high-side switch integrates protection, diagnosis, and PWM capability into one IC, simplifying the ECU design and reducing PCB area. Key features include very low standby current (a few µA typical), CMOS-compatible input thresholds, fast demagnetization of inductive loads via integrated active Zener clamps, stable behavior at undervoltage, and a defined restart behavior after over-current or thermal shutdown. Each channel provides its own status feedback and fault flag through a shared diagnostic output, allowing the microcontroller to distinguish between normal operation, short circuit to ground, short circuit to battery, and open load conditions. The BTS723GWXUMA1 is fabricated using Infineon's proprietary SMART7 vertical power technology, which delivers very low R_DS(on) per channel, strong avalanche ruggedness, and tight thermal coupling between the two output FETs on a single die. The PG-DSO-14-37 package exposes a thermal pad on the underside for PCB copper cooling, enabling sustained 2× 2.5 A operation without external heatsinks in typical 12 V automotive body-control modules. Typical applications include automotive body electronics (door modules, seat controllers, mirror fold), dual-rail lamp drivers (interior lighting, turn indicators), HVAC blower and resistor switching, and any 12 V/24 V load where two independent high-side channels are needed with full protection and ISO 7637-2 transient immunity. The wide operating voltage range (6 V to 24 V nominal, with load-dump survival to 40 V per the Classic PROFET specification) makes the part equally suitable for trucks and 24 V commercial-vehicle platforms. When designing with this part, place the input pin capacitor (typically 100 nF) as close as possible to the Vbb pin and route the two output channels with wide copper pours to keep the on-state resistance low and share heat between channels. Always respect the maximum energy rating during demagnetization (E_AS) when switching inductive loads, otherwise the active clamp Zener can be permanently damaged.

BTS724GXUMA1 - 4-Ch High-Side Smart Power Switch 3A | Infineon
The Infineon BTS724GXUMA1 is a 4-channel high-side power switch with integrated vertical power MOSFETs in a 20-pin PG-DSO-20 package. Each channel delivers up to 3 A continuous load current from a 5.5 V to 38 V supply, making it well suited to drive resistive, capacitive, and inductive loads in 12 V and 24 V automotive and industrial systems. Built on Infineon's Smart SIPMOS technology, the device embeds a charge pump, CMOS-compatible ground-referenced inputs, and per-channel status feedback, enabling direct connection to a microcontroller without level shifters. A high-side power switch is a semiconductor device that sits between the supply rail and the load, controlling current flow while providing protection. In the broader taxonomy, the BTS724 belongs to the high-side switch family, itself a sub-category of power distribution switches under power management ICs. Compared to low-side switches, high-side drivers keep the load referenced to ground when off, simplifying wiring harnesses and improving safety in automotive body and chassis applications. Key features include 4 independent channels with 3 A continuous current per channel, very low standby current for quiescent-sensitive designs, fast demagnetization of inductive loads, embedded protection (overload, short-circuit, over-temperature, and over-voltage at Vbb(AZ)), stable behavior at undervoltage, and improved electromagnetic compatibility (EMC). The diagnostic output reports channel fault conditions to the MCU for centralized fault handling. Architecturally, the BTS724G combines an internal charge pump to drive the N-channel vertical MOSFETs from a 5 V logic input, plus an integrated sense-FET and bandgap-based thermal sensor per channel. The PG-DSO-20 package offers a small PCB footprint while dissipating up to approximately 1.8 W total, adequate for the typical 4-channel automotive body control scenario. Typical applications include automotive body electronics (lighting, seat heating, mirror control), industrial PLC outputs, 24 V factory automation drivers, and any multi-load distribution node requiring per-channel diagnostics. When designing, ensure the total package dissipation stays below the datasheet derating curve and add reverse-battery protection (e.g., a series diode or P-MOSFET) for harsh 12 V automotive environments. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
BTS740S2XUMA1 - Dual 4.9A Smart High-Side Switch | Infineon
The Infineon BTS740S2XUMA1 is a dual-channel smart high-side power switch built on PROFET™ technology, providing two independent 4.9 A N-channel MOSFET output stages in a 20-pin PG-DSO-20 (Power Small Outline) package. Each channel integrates a vertical power FET with embedded protection and full diagnostic feedback, designed for harsh 12 V automotive and industrial power distribution. The device operates from a 5 V to 24 V logic supply with load compatibility up to 28 V, delivering clean, ground-referenced switching for lamps, solenoids, and relays. A high-side power switch is a semiconductor that controls the positive (battery) rail feeding a load, rather than the low-side ground return. Placing the switch on the high side lets the load chassis and wiring remain at 0 V when the switch is open, eliminating ground-loop faults and improving diagnostics. The BTS740S2XUMA1 sits inside the broader family of PROFET™ protected switches, which belong to the power management and power distribution IC category used in body-control modules, BCMs, and zonal architectures where each actuator requires short-circuit, over-voltage, and thermal protection. Key features include CMOS-compatible input pins with separate logic ground, undervoltage and overvoltage shutdown with auto-restart and hysteresis, fast demagnetization of inductive loads, and very low standby current. The two channels can be paralleled for higher current loads, while diagnostic outputs report open-load and short-to-battery/ground conditions to the host microcontroller. Embedded protection also includes overtemperature shutdown and load-current limitation. The BTS740S2 architecture uses a vertical DMOS power stage that achieves a low R_DS(on) per channel and handles the inductive kickback of relays and solenoids through an active fast-demagnetization circuit. This clamp-and-recover approach eliminates the need for external freewheeling diodes and preserves the automotive 12 V transient immunity required by ISO 7637 and similar load-dump standards. Typical applications include automotive body electronics (door lock, mirror fold, seat heating), 24 V industrial actuator drivers, PLC digital outputs, and any system where multiple high-current resistive or inductive loads must be switched with full protection. Designers commonly pair this part with a microcontroller such as the Infineon TLE987x or a 3.3 V/5 V MCU from the PIC or STM32 families. When designing with this device, ensure the logic ground is referenced correctly to the host MCU and that a small RC filter is placed on each input pin to suppress automotive transients. Note that thermal derating is required when both channels operate near full load simultaneously, because the PG-DSO-20 package shares a common copper pad. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the Infineon manufacturer datasheet alone, helping engineers select and qualify the BTS740S2XUMA1 for new designs.
BTS7810K - TrilithIC Quad-DMOS H-Bridge Driver | Infineon
The Infineon BTS7810K is a TrilithIC quad-DMOS switch from the NovalithIC family, integrating one double high-side switch and two low-side switches in a single P-TO263-15-1 (PowerPak) surface-mount package. It is free-configurable as a full bridge, half bridge, or quad-switch topology, with typical RDS(on) of 26 mΩ on the high-side and 14 mΩ on the low-side switches at 25 °C, and a maximum peak current capability of 42 A at 25 °C. The device is optimized for DC motor management applications and operates from a logic-level supply. What is a TrilithIC / NovalithIC? A NovalithIC is a fully protected half-bridge or multi-switch power IC that integrates one or more vertical DMOS power stages with on-die charge pump, gate control and diagnostic circuitry. It sits in the broader hierarchy: power MOSFET driver -> half-bridge driver -> motor driver IC -> power management semiconductor. By placing three dice in one package with shared control logic, NovalithIC parts replace discrete H-bridge designs, shrinking PCB footprint, reducing parasitic inductance, and providing built-in protection that would otherwise require external circuitry. Key features include load and GND short-circuit protection, very low quiescent current of 4 µA typical at 25 °C, a small outline thermally-optimized PowerPak package, and the ability to be combined with an additional NovalithIC to create an H-bridge or three-phase bridge. The device is designed to switch fast PWM signals while providing over-current, under-voltage and over-temperature protection, making it suitable for brushed DC motor control. Typical applications include DC motor management in automotive body electronics, robotic actuators, industrial automation drives, power tool motor control, valve and pump drivers, and HVAC blower control. The configurable topology supports bidirectional motor control with a single IC, eliminating the need for separate high-side and low-side driver stages. When designing with the BTS7810K, ensure adequate copper area for thermal dissipation because the device can deliver up to 42 A peak current. Place the bootstrap or charge-pump capacitors close to the package, and follow Infineon's recommended PCB layout guidelines to minimize parasitic inductance in high-current switching paths.

The Infineon BTS80009SWPF1ESXUMA1 is a 12V smart high-side power switch (SPOC family) delivering up to 34.5A nominal load current in a PG-TSDSO-24-75 package. It integrates wire-guard I²t protection, overcurrent shutdown, and a 24-bit SPI interface with CRC for digital diagnostics and configuration. The part is qualified to ISO 26262 ASIL-D for functional safety and is designed as a one-to-one drop-in for relays, fuses, and discrete MOSFET high-side stages in 12V automotive power distribution. A smart high-side switch is a semiconductor replacement for an electromechanical relay plus fuse that controls DC loads (lamps, solenoids, motors, heaters) from the positive rail. SPOC devices combine a vertical power MOSFET, charge pump, gate driver, current sense, and protection logic in a single IC, which makes them far more compact and diagnosable than discrete solutions while supporting PWM and load-sharing across multiple switches. The BTS80009-SWPF-1ES is the flagship of Infineon's Wire-Guard family, adding integrated I²t wire-protection curves so the harness gauge can be sized exactly to the load profile without external fuse selection. Key features include 1:1 power switch topology, 34.5A nominal / much higher inrush capability, ISO 26262 ASIL-D compliance, integrated I²t wire-guard protection, configurable overcurrent shutdown, open-load detection in on and off states, short-to-ground and short-to-battery diagnostics, ground-loss detection, thermal shutdown with restart, and a 24-bit SPI port for daisy-chained diagnostics across multiple SPOC channels. The PG-TSDSO-24-75 exposed-pad package provides a low thermal resistance path for sustained high-current operation. Typical applications include 12V automotive body and powertrain ECUs, fuse and relay replacement in power distribution boxes, fail-operational power supply rails, ECU main switches, load-shedding circuits, and zonal architectures where one MCU monitors many smart switches via a single SPI bus. The digital status feedback enables predictive maintenance and ISO 26262 fault-tolerant system design. When designing with the BTS80009SWPF1ESXUMA1, observe Infineon's PCB layout guidance for the exposed pad, keep the SPI traces short and matched, and use the integrated I²t curves to select wire cross-section rather than adding external fuses.

The device is specified for junction temperatures from -40 °C to +150 °C, suiting under-the-hood automotive environments. The BTT3050EJXUMA1 belongs to the HITFET+24V family of smart low-side switches, which sit in the broader hierarchy of power distribution switches -> load drivers -> power management ICs. Low-side switching architectures return the load to battery ground, simplifying protection and ground-referenced diagnostics, and are widely used for resistive, inductive, and capacitive loads in body electronics, powertrain auxiliaries, and industrial 24 V systems. Internally, an N-channel vertical MOSFET handles the load current while logic-level CMOS gates drive the protection, current-sensing, and thermal-foldback blocks. The exposed thermal pad (PG-TDSO-8-31) provides a low θJA path, allowing 4 A continuous operation without an external heatsink when soldered to adequate copper area on the PCB. Typical applications include automotive body electronics (door locks, mirror heaters, seat controls), LED lighting drivers, 24 V industrial actuators, HVAC valves, and relay replacements. The integrated protection eliminates the need for external fuses or TVS clamp networks on every load branch, reducing BOM cost and PCB area in ECU designs. When designing with the BTT3050EJXUMA1, route the diagnostic pin to a microcontroller ADC or GPIO and respect the recommended PCB copper footprint to keep junction temperature within SOA at maximum ambient. For inductive loads, an external free-wheeling diode is not strictly required but is recommended for repetitive switching of large solenoids.

The Infineon BTT60101ERBXUMA1 is a 10 mΩ single-channel Smart High-Side Power Switch built on Infineon's Smart6 technology, providing protective functions and diagnostic feedback in a PG-TDSO-14 Exposed Pad package. The part delivers up to 9 A continuous load current, operates from 5 V to 36 V supply, and integrates an N-channel vertical power MOSFET with charge pump, current sense, and digital status output. What is a Smart High-Side Power Switch? A high-side switch is a semiconductor device that sits between a power supply and its load, controlling current flow on the positive (high) side of the circuit. Compared to a discrete MOSFET, a "smart" high-side switch adds gate driving, charge pump generation, current sensing, thermal protection, short-circuit handling, and open-load detection. In the broader power-management hierarchy, smart high-side switches sit between simple load switches and full eFuse / SBC (System Basis Chip) devices, becoming the preferred solution for automotive 12 V/24 V body electronics where diagnostic feedback and AEC-Q100 reliability are required. Key features include an on-state resistance of 10 mΩ typical, integrated reverse-battery protection up to -36 V, very low standby current, and a current sense pin (IS) with a defined kILIS ratio for load-current monitoring. The BTT60101ERBXUMA1 also provides programmable restart behavior after short-circuit or overtemperature events, an active-high input (IN), and a status feedback pin (ST) for fault communication to a host microcontroller. These features are documented in the Infineon BTT6010-1ERB datasheet. The device is manufactured in Infineon's Smart6 process, which combines a robust N-channel vertical DMOS output stage with on-chip CMOS control logic. The exposed pad of the PG-TDSO-14 package keeps junction-to-ambient thermal resistance low, allowing the part to drive heavy loads such as 5×P21W 24V automotive lamps or 1×H55W 12V lamps without external heatsinking on moderate copper area. Typical applications include automotive body electronics (lamp drivers, seat heaters, mirror heaters), industrial 24 V PLC outputs, 24 V/48 V truck and off-road vehicle loads, and replaceable fuse emulation in 12 V/24 V systems. In each case the part replaces a relay + fuse + shunt-resistor triad, delivering solid-state reliability and built-in diagnostics. When designing with the BTT60101ERBXUMA1, ensure the input pin (IN) logic levels are compatible with your 3.3 V or 5 V MCU, place the device near the connector to minimize wire resistance, and follow Infineon's PCB layout recommendations for the exposed pad and current-sense path to preserve current-mirror accuracy.

The Infineon BTT6020-1ERA is a 20 mΩ single-channel Smart High-Side Power Switch in a 14-pin PG-TDSO-14 Exposed Pad package, rated for 7 A continuous load current on 12 V/24 V automotive rails. Built on Infineon's Smart6 technology, the device integrates an N-channel vertical power MOSFET with charge pump and comprehensive protection and diagnostic features. It is specially designed to drive lamps up to 5 x P21W 24V or 1 x 70W 24V, as well as LEDs in harsh automotive environments. A Smart High-Side Switch (also called PROFET, or Protected Smart FET) is a type of intelligent power switch used to control resistive or inductive loads from a microcontroller. Compared to a discrete MOSFET, a smart high-side switch integrates the power transistor, gate charge pump, current limiting, thermal shutdown, ESD protection, and a diagnostic feedback path into one package. It sits within the broader power-management IC hierarchy (power switch -> load driver -> PMIC -> semiconductor) and is preferred over discrete solutions for body-electronics modules because it eliminates dozens of external components and provides MCU-readable fault feedback. Key features include a typical on-state resistance of 20 mΩ, 24 V load-dump ruggedness (per automotive transients), over-current protection, short-circuit protection with latch behavior, thermal shutdown, over-voltage clamp at the output, under-voltage lockout, reverse-battery protection on Vbb, ESD protection on IN/DEN, and a current-sense diagnostic pin with proportional load current output. The exposed pad on the PG-TDSO-14 package keeps junction temperature manageable at full 7 A load by reducing thermal resistance to roughly 35 C/W on a properly designed 2-layer FR4 board. Typical applications include automotive body-control modules driving 24V incandescent lamps, halogen or LED exterior lighting, seat-heater and mirror-heater PWM control, DC-brush motor control, and any 24V body-electronics load where MCU-driven fault diagnostics are required. The 24V load-dump capability and AEC-Q100 qualification make it well suited for truck, bus, and off-highway vehicles, as well as 12V passenger cars with standard 12V/24V jump-start transients. When designing with this device, place a low-ESR ceramic or electrolytic capacitor near the Vbb pin to absorb load-dump transients and meet the input-voltage stability analysis on the IN pin. The DEN diagnostic pin current must be converted to a voltage with a sense resistor scaled to the MCU ADC full scale. Always check the worst-case SOA curve (DC and 1-second pulse) at your highest inrush load to verify that cold-filament lamp turn-on stays below the safe-operating-area boundary.

The device is housed in a 14-pin PG-DSO-14-40 EP package with an exposed thermal pad that drops the junction-to-ambient thermal resistance to a level suitable for sustained high-current switching without external heatsinking. A high-side switch is a semiconductor relay that sits between the supply rail and the load, controlling current flow when turned on and providing both load-side protection and ground-referenced diagnostics. PROFET (Protected MOSFET) is Infineon's branding for its family of intelligent high-side switches that combine a power MOSFET with on-chip protection, diagnosis, and gate-drive circuitry; this part sits in the broader taxonomy of N-channel MOSFET -> power switch -> power management IC -> semiconductor, and is commonly used to replace electromechanical relays and discrete MOSFET-plus-driver arrangements. Key features include integrated protection functions (short-circuit, over-load, over-voltage, over-temperature), current-limit trip thresholds set for safe activation of incandescent lamps and capacitive loads, an analog diagnostic current-sense output proportional to the load current, and dedicated ground-referenced input pins for each channel. The AEC-Q100 automotive-grade qualification, combined with the 28 V load-dump tolerance expected of 12 V automotive systems, makes it especially suitable for body-electronics modules, junction boxes, and BCMs. The device is built on Infineon's SMART7 high-side technology platform, which adds digital status feedback, slew-rate control for EMI reduction, and a reverse-battery protection concept. Channels are independently controllable through CMOS-compatible input pins, allowing PWM-driven loads such as LEDs, solenoids, and DC motors. Typical applications include automotive lighting (headlamps, tail lamps, turn signals), heating elements such as seat heaters and rear-window defrosters, DC motor drives (window lifters, door locks, mirror adjusters), solenoid and valve control, and replace-ment for traditional automotive relays and fuses in distributed body-electronic architectures. When designing with this part, verify that the steady-state load current stays below the 4 A per-channel limit with adequate margin for inrush (lamp, capacitive, or motor loads). The exposed pad must be soldered to a sufficient PCB copper pour to keep junction temperature within the operating range; refer to Infineon's PROFET application notes for derating curves.

Each channel integrates an N-channel vertical power MOSFET with charge pump, current limiting, and comprehensive diagnostic feedback. A high-side power switch (also called a smart high-side driver) is a power distribution IC that sits between the battery/supply rail and a load (lamp, solenoid, motor, heater). It replaces a mechanical relay or discrete fuse/MOSFET solution by providing solid-state switching plus on-chip protection (overcurrent, overtemperature, short-to-ground/battery, ESD) and load-diagnostic feedback to the MCU. High-side switches belong to the broader category of power distribution switches under PMIC (Power Management IC). Compared with low-side switches, high-side drivers eliminate ground-loops and simplify load-fault detection. Key features of the BTT60302ERAXUMA1 include a typical on-state resistance of 32 mΩ per channel at 25 °C, an operating supply range of 8 V to 36 V (load-dump tolerant up to 42 V), continuous current up to 4 A per channel, AEC-Q100 automotive qualification, and very low standby current. The device is built in Infineon's Smart6 technology, integrating the power MOSFET, charge pump, gate driver, and protection/diagnostic logic in one die. Typical applications include automotive body electronics (door modules, seat controllers, lighting drivers), resistive/inductive load driving (heaters, valves, small DC motors), and 24 V truck/commercial-vehicle power distribution. The dual-channel integration halves PCB area versus two single-channel switches, and the built-in diagnostic current sense (IS pin) enables open-load and short-circuit detection without extra shunt resistors. When designing with this part, observe the exposed-pad thermal layout: the EP must be soldered to a minimum 1 cm² copper area to keep junction temperature within the 150 °C limit under worst-case load-dump and parallel-channel operation. Use a 100 nF X7R ceramic bypass on Vbb close to the pin to suppress supply transients. The IS pin output is analog; route it away from switching nodes and add an RC filter (~1 kΩ + 100 nF) to ground to clean up PWM edge ringing.

A PROFET (Protected MOSFET) smart power switch is a class of intelligent high-side drivers that combine an N-channel power MOSFET with on-die protection, diagnostics, and load-driving logic. PROFETs sit in the system hierarchy between discrete MOSFETs and full ECU power-management ICs, providing protected, diagnosable switching of resistive, capacitive, and inductive loads while offloading fault handling from the microcontroller. Key features include 4 A continuous output current per channel, 32 mOhm typical on-resistance, integrated protection against over-current, over-voltage, over-temperature, short-circuit, and reverse battery conditions, plus a status feedback pin for load-diagnosis. The 1:1 input-to-output logic enables direct GPIO control from a 3.3 V or 5 V microcontroller without level shifting. The exposed thermal pad (PG-TDSO-14-31) provides a low theta_JC for heat extraction into the PCB copper pour. The BTT60302ERBXUMA1 uses Infineon's PROFET smart-power architecture, embedding charge pump, gate driver, current sense, and protection circuitry alongside the power MOSFET. This monolithic integration reduces BOM count, eliminates external protection components, and provides per-channel diagnostics that are critical for functional-safety and ASIL-rated systems. The device is AEC-Q100 qualified, making it suitable for harsh automotive electrical environments including load-dump and jump-start transients. Typical applications include automotive body controllers (lighting, seat heaters, mirror adjusters), industrial 24 V PLC discrete outputs, HVAC valve and damper drivers, and any 12 V/24 V system that requires protected high-side switching with diagnostic feedback. Its dual-channel integration halves PCB area versus two single-channel PROFETs. When designing with this device, ensure the PCB thermal pad receives adequate copper (at least 1 square inch for full 4 A per channel) to keep junction temperature within SOA.

Each of the four channels is rated for 1 A nominal load current, making the device suitable for driving lamps, LEDs, relays, and solenoids in body and powertrain ECUs. What is a Smart High-Side Switch? A high-side switch sits between the battery positive rail and the load, controlling current flow into lamps, motors, or actuators. The "Smart" qualifier means the device integrates, beyond the power MOSFET, protection logic (overload, short-circuit, over-temperature, over-voltage), diagnosis (current-monitor output, fault flag), and a charge pump to fully enhance the N-channel MOSFET from the battery rail. This category sits within power distribution ICs -> power switches -> high-side drivers -> automotive qualified MOSFETs. Key features include a typical on-state resistance of 200 mΩ per output, very low quiescent current in stand-by, PWM capability for dimming functions, current sense diagnostics with proportional analog IS pin, and integrated reverse-battery protection via the ground-referenced logic interface.

CAP014DG - X Capacitor Discharge IC | Power Integrations
The Power Integrations CAP014DG is a zero-loss automatic X capacitor discharge IC housed in an 8-pin SO (SOIC-8) package, designed for AC-DC switched-mode power supplies that must comply with international safety standards such as IEC 60950 and IEC 60065. When AC mains voltage is present, the CAP014DG blocks current flow through the X-capacitor safety discharge resistors, reducing standby power loss to less than 5 mW, or essentially zero at 230 VAC. When AC is removed, the device automatically reconnects the discharge path so the X capacitor is safely bled down to a touch-safe voltage. This behavior is critical for meeting the one-second discharge requirement of modern energy-efficiency standards without the continuous dissipation that discrete discharge resistors impose. An X capacitor discharge IC is a specialized power-management block that solves the standby-power vs. safety-discharge trade-off in AC-DC converters. The CAP014DG sits in the X-capacitor discharge path on the AC side of the bridge rectifier; it acts as an AC-active switch that is open (high-impedance) when line voltage is present and closed (low-impedance) when line voltage is removed, providing safety discharge without wasting power. This category belongs to the broader hierarchy: power management IC -> specialized PMIC -> capacitor discharge IC -> safety/discharge sub-system. CAPZero-family devices are widely used in adapters, open-frame SMPS, and TV/monitor standby rails where 5 mW of standby loss matters. Key features of the CAP014DG include support for X-capacitor values up to 1000 nF (1 uF) total, blocking voltage of 1000 V, low leakage in the on-state, simple two-terminal interface that needs no external control signal, and integrated voltage detection that distinguishes AC present vs. AC absent. The device uses the AC line itself to sense when it should enter the blocking or the discharge mode, so no auxiliary bias supply is needed. Because the IC is series-connected with the discharge resistors, it is designed to survive repetitive AC line transients and meets the basic-insulation requirements for primary-side touch-safe discharge paths. Typical applications include smartphone and tablet adapters (5 W to 65 W USB-PD), TV and monitor standby supplies, white-goods SMPS (washing machines, refrigerators), industrial PLC power supplies, and any AC-DC converter that must meet IEC 62368-1, IEC 60950-1, or ENERGY STAR standby limits. The CAP014DG is especially valuable in designs targeting the European EuP and U.S. DoE Level VI standby tiers, where total no-load consumption must be below 75 mW to 300 mW depending on output rating. When designing with the CAP014DG, route the device in series with the two discharge resistors across the X capacitor, and keep trace lengths short to avoid nuisance tripping during line transients. Verify that the chosen X capacitor total value does not exceed 1000 nF, otherwise discharge time will exceed the one-second safety limit. Add a single high-voltage Y-cap on the AC sense pin if the application environment contains fast line transients.
CAP014DG-TL - 1000V X Capacitor Discharge IC | Power Integrations
The Power Integrations CAP014DG-TL is an automatic X capacitor discharge IC rated for 1000V operation supporting up to 1000 nF X capacitor capacitance, housed in an 8-pin SOIC package. It belongs to Power Integrations' CAPZero family of zero-loss automatic X capacitor discharge ICs designed for AC-DC converters. What is an X capacitor discharge IC? An X capacitor (across-the-line safety capacitor) requires a discharge path when AC mains is removed to meet safety standards such as IEC 62368-1. Traditional discharge resistors waste several milliwatts continuously, reducing standby efficiency. An X capacitor discharge IC replaces these resistors with a smart switch that blocks current during normal operation and engages discharge resistors when AC is disconnected - eliminating standby loss while maintaining safety compliance. Key features include 1000V peak voltage rating, support for up to 1000 nF X capacitors, ultra-low standby power of less than 5 mW at 230 VAC, automatic discharge activation when AC is removed, and compatibility with converter/ACDC applications across the 80 VAC to 265 VAC universal input range. The 8-SOIC package enables easy integration into existing flyback, buck, or other AC-DC converter layouts with minimal PCB area. The CAP014DG-TL uses two back-to-back high-voltage MOSFETs with intelligent sensing to detect AC presence. When AC voltage is applied, the internal switches are off and no current flows through the discharge resistors. When AC is removed, the IC detects the absence and closes the switches, allowing the discharge resistors to safely bleed the X capacitor voltage below the 34V safety threshold within one second as required by safety standards. Typical applications include adapters and chargers for consumer electronics, smart home and IoT devices, standby power supplies in white goods, ultra-low standby power AC-DC converters, and USB-PD power adapters. The device is particularly valuable in designs targeting Energy Star and EU Ecodesign standby limits below 500 mW. When designing with this device, pair the CAP014DG-TL with a matched X capacitor whose value does not exceed 1000 nF. Ensure trace spacing on the high-voltage pins complies with IEC 62368-1 creepage and clearance requirements. Confirm that the total discharge time meets the safety standard in your target region.

The device communicates over the standard I2C bus (compatible with SMBus) and supports two programmable blink rates plus full ON/OFF control per channel. An LED driver I/O expander is a specialized interface IC that combines a general-purpose I/O port expander with constant-current or constant-voltage LED drive transistors on each bit. Within the broader semiconductor taxonomy, the CAT9532 sits in the LED driver subcategory of power management, with hypernyms: LED driver -> display driver -> power management IC -> semiconductor. The integrated dimming logic offloads PWM generation from the host MCU, reducing firmware complexity and freeing timer resources for other tasks. Key features include 16 independently controlled LED drivers with 256 brightness levels, two programmable blink rates, hardware address pins that allow up to four devices on the same I2C bus, and a wide operating supply range suitable for 3 V and 5 V systems. The device also functions as a general-purpose 16-bit I/O expander when LED dimming is not required, providing bidirectional GPIOs with interrupt capability. Architecturally, the CAT9532 integrates CMOS output drivers with a programmable PWM/FSK engine, an I2C-compatible slave interface, and configurable registers per channel. The 4x4 mm TQFN package provides a low thermal-resistance path and supports compact PCB designs for space-constrained backlight, indicator, and RGB lighting modules. Typical applications include RGB LED backlighting in handheld and industrial displays, status-indicator panels, keypad backlights, decorative color-mixing lighting, and any 3 V/5 V system that needs up to 16 individually dimmed LEDs. Each output can also serve as a standard GPIO when the LED function is disabled, adding flexibility for mixed-signal designs. When designing with the CAT9532, ensure that the per-channel current setting resistors are chosen based on the LED forward voltage and supply rail. The HVQCCN exposed pad should be soldered to a sufficient copper area for thermal dissipation when multiple channels operate near 25 mA simultaneously.

The onsemi CAT9532HV6I-GT2 is a CMOS 16-bit I/O expander optimized for LED dimming and blinking, providing 16 parallel input/output channels with 25 mA sink capability per channel in a 24-pin TQFN (4x4 mm) package with exposed pad. It operates from a supply voltage of 2.3 V to 5.5 V over the industrial -40 C to +85 C temperature range, and communicates to a host controller over a standard I2C/SMBus interface up to 400 kHz. An LED driver IC is a semiconductor device that translates low-current logic-level control signals into higher-current outputs capable of directly driving discrete LEDs or LED arrays. In the broader system hierarchy, the CAT9532HV6I-GT2 sits in the power management and display backlight category as a programmable constant-current-style sink, controlled by a serial bus; it is commonly used as a co-processor offload for microcontrollers that lack sufficient GPIO pins or PWM channels to drive many LEDs simultaneously. Key features include per-channel programmable on/off, two internal PWM generators (PWM0/PWM1) for shared duty-cycle control, software programmable blink rates from 0.25 Hz to 7.81 Hz with duty cycle of 0% to 99.6%, hardware address pins (A0/A1/A2) allowing up to 8 devices on the same I2C bus (128 LEDs total), and an open-drain active-low interrupt output. The 24-TQFN-EP package provides low junction-to-board thermal resistance for reliable continuous sink operation. Internally the CAT9532HV6I-GT2 uses a CMOS logic core with two 8-bit configuration registers, two 8-bit frequency-prescaler registers, and PWM duty-cycle registers. A single 6 MHz internal oscillator drives both PWM channels independently, allowing mixed-rate blinking across the 16 outputs without host CPU intervention. Typical applications include keypad backlighting, status-indicator LED arrays, RGB LED string control, white-good front-panel indicators, automotive interior lighting (infotainment / instrument clusters when paired with Q-grade parts), and any host-limited system that needs 16+ individually dimmable LEDs. When designing with this part, observe the 25 mA per-pin continuous sink rating, derate for ambient temperature, and place a 0.1 uF decoupling capacitor within 5 mm of VCC. The exposed pad (EP) must be soldered to a thermal land of at least 16 mm^2 of inner-layer copper.
