BTS70082EPZXUMA1 - Dual 7.5A Smart High-Side Switch | Infineon
The Infineon BTS70082EPZXUMA1 is a dual-channel smart high-side power switch (PROFET+2 family) rated for 7.5 A continuous load current per channel, housed in a PG-TDSO-14-11 (SOIC-14 with exposed pad) package. The device integrates two N-channel MOSFET output stages with 9 mOhm (typ) on-resistance per channel, plus comprehensive protection and diagnostic functions including overcurrent, overtemperature, overvoltage, and undervoltage protection with configurable fault reset behavior. Operating supply voltage spans 4.1 V to 28 V, with logic-level inputs accepting 3.3 V and 5 V microcontroller signals. A high-side power switch is a semiconductor device that connects a load to the positive supply rail while providing controlled turn-on/turn-off, current limiting, and fault feedback. PROFET devices belong to the broader category of intelligent power switches (IPS), which sit between simple power MOSFETs and fully integrated H-bridge motor drivers. They are commonly used in automotive body electronics to replace mechanical relays and fuses with solid-state switching, enabling PWM-based load control and diagnostic feedback over CAN or LIN networks. Key features include very low standby current, separate diagnostic feedback for each channel via the IS pin current sense output, reverse battery protection capability with an external resistor, ground-loss detection, and AEC-Q100 qualification for automotive use. The exposed thermal pad reduces junction-to-ambient thermal resistance to 35 C/W, supporting sustained 7.5 A operation on moderate copper area. Internally, the BTS70082EPZXUMA1 uses a vertical N-channel DMOS process with an embedded charge pump to drive the gate above the battery rail. The integrated current sense delivers a proportional analog current at the IS pin that the microcontroller can digitize with an ADC for load-diagnostics (open load, short circuit, normal operation). Each channel has independent input control, allowing two loads to be driven from one IC. Typical applications include automotive lighting (headlamp, tail, interior LED), heating elements (PTC heater booster, seat heater), DC motors (window lift, fuel pump, fan), and solenoid/valve drivers. The device is well suited for body control modules and zone ECU designs where two independent high-side channels are needed with full protection. When designing with this part, keep input pins below 5.5 V even during load-dump transients up to 35 V (a series resistor or TVS is typical), place the sense resistor close to the IS pin to avoid noise pickup, and ensure the exposed pad is soldered to at least 1 cm squared of copper for full current capability. Reverse-battery protection requires an external N-channel MOSFET in the ground return or series resistor on Vbb.

BTS70101EPAXUMA1 - 9A Smart High-Side PROFET Switch | Infineon
The Infineon BTS70101EPAXUMA1 is a 9 A single-channel smart high-side N-channel power switch from the PROFET+2 family, fabricated in SMART7 technology and housed in a PG-TSDSO-14-22 (TSSOP-14 with exposed pad) package. It provides a 1:1 power switch/driver function for automotive 12 V load management with proportional load-current sensing and full diagnostic feedback. A high-side N-channel MOSFET switch (also called a smart high-side driver) is a power distribution topology where the load connects to ground and the switch sits between the positive rail and the load. Compared with low-side switching, high-side drivers offer inherent short-to-ground protection, controlled inrush-current behavior, and native compatibility with chassis-referenced vehicle loads. The PROFET+2 family targets intelligent power distribution in body and powertrain ECUs where ISO 7637-2 transient immunity and AEC-Q100 qualification are mandatory. Key features include 9 A nominal load current, integrated reverse-battery protection (ReverSave), embedded thermal shutdown, over-current latch, open-load detection in both on and off states, and proportional load-current sensing via the IS pin. Operating supply voltage spans 6 V to 18 V with load-dump tolerance above 40 V, and the part is AEC-Q100 qualified for automotive use. The exposed thermal pad of the PG-TSDSO-14-22 package keeps junction-to-ambient thermal resistance low for continuous high-current loads such as seat heaters and HVAC blowers. The BTS70101EPAXUMA1 integrates a vertical N-channel power MOSFET with a sophisticated analog/mixed-signal control and protection block, achieving diagnostic feedback comparable to discrete designs while maintaining the simplicity of a single-channel IC. Built-in protections reduce external BOM and PCB area versus discrete MOSFET-plus-fuse topologies. Typical applications include automotive body controllers (BCM), HVAC blower and fan control, seat-heater and door-module drivers, LED driver front-ends, and industrial 24 V systems requiring protected switching. Engineers select the BTS70101EPAXUMA1 when they need a single channel of clean, diagnosed high-side switching rather than a quad-channel low-side array. Companion devices include the BTS7080-2EPA and BTS7120-2EPA within the PROFET+2 family. Design consideration: dedicate a continuous copper pour under the exposed pad to module ground, keep the IS sense trace short and shielded, and use ReverSave to meet ISO 7637-2 reverse-polarity requirements without an external blocking diode. This page synthesizes distributor stock, AEC-Q100 verified drop-in alternatives from the PROFET+2 family, and practical design notes that go beyond the manufacturer datasheet's typical-application section.
BTS70121EPAXUMA1 - 8.5A Smart High-Side Power Switch | Infineon
The Infineon BTS70121EPAXUMA1 is an 8.5 A single-channel smart high-side power switch from Infineon's PROFET+2 family, housed in a 14-pin PG-TSDSO-14 EP (exposed pad) package with a 0.65 mm pin pitch. The device integrates a 2x8 mOhm N-channel MOSFET output stage, giving it the lowest on-state resistance in the PROFET+2 lineup and supporting the harshest reverse-battery requirements on the market. A high-side power switch (also called a smart power switch or PROFET - Protected FET) is a semiconductor device that sits between an upstream supply (typically a vehicle battery) and a downstream load. By placing the switch on the high side, current flows from the supply through the switch to the load, allowing the switch to control, protect, and diagnose the load. PROFET devices are a sub-category of power distribution switches within PMIC (Power Management IC) products, and they are widely used in automotive body and powertrain ECUs. Key features of the BTS70121EPAXUMA1 include an 8.5 A continuous load current capability, integrated protective functions (overload, short-circuit, over-temperature, over-voltage, reverse battery), and current-limit / ground-loss diagnostics. According to Infineon's PROFET+2 family documentation, the part is qualified to AEC-Q100 for automotive applications, ships in tape-and-reel packaging, and offers two-wire or direct-switch interface options depending on the variant in the family. The exposed pad on the PG-TSDSO-14 package provides a low-thermal-resistance path, helping dissipate the heat generated when the device drives high-current loads. Typical applications include automotive body electronics (lighting modules, seat heaters, mirror controls), powertrain auxiliary drivers, and industrial 24 V systems that benefit from a robust, self-protected high-side driver. Because the switch handles inrush currents, short circuits, and ground-loss events autonomously, the host microcontroller does not need to implement complex fault-recovery firmware. When designing with this part, place input bulk capacitance close to the Vbb pin to absorb load-dump transients and follow Infineon's PCB layout recommendations for the PG-TSDSO-14 thermal pad to keep junction temperature within the AEC-Q100 envelope. The lowest 8 mOhm per channel rating in this family makes it well suited for high-current loads where conduction losses dominate system efficiency.

Each of the two channels can deliver up to 2.5 A continuous, with the device rated for a total load current of 5 A, an operating voltage range of 6 V to 18 V (load dump tolerant up to 28 V per the PROFET family spec), and an integrated N-channel MOSFET output stage per channel. The part is supplied on tape-and-reel with the -XUMA1 packing suffix. A high-side power switch is a semiconductor device that sits between the supply rail and the load, replacing a relay or discrete MOSFET+driver pair. It controls power to resistive or inductive loads such as lamps, solenoids, motors, and LED strings, while also providing protection and diagnostic feedback. Within the broader power-management hierarchy, high-side switches sit alongside low-dropout regulators (LDOs) and DC-DC converters as system-level power-conditioning blocks; within Infineon's PROFET+ family, they are the most integrated option, embedding protection, driving, and sensing into a single die. The BTS70202EPAXUMA1 integrates per-channel protection: load-current limitation, short-circuit shutdown, over-temperature latch-off, over-voltage clamp (including inductive load demagnetization), reverse-battery protection through an external ground-referenced resistor network, and loss-of-ground/battery detection. Each channel also provides an analog current-sense (IS) pin that scales with load current for ADC-based diagnostics, plus a dedicated enable input for PWM and multiplexing flexibility. A key feature is the configurable current-limit setpoint (default ~12 A ICL0, with selectable ICL1 thresholds via the SEL pin) and a typical on-state resistance of about 30 mΩ per channel, which keeps conduction losses low at full load. The device supports 3.3 V and 5 V microcontroller logic on its input pins and meets the strict electromagnetic-compatibility requirements of automotive body and chassis ECUs. Typical applications include automotive body control modules for driving LED tail-lights, interior lighting, and seat heaters; industrial PLC digital outputs; 24 V industrial sensor and actuator power; and any 12 V/24 V distributed power system needing per-channel fault reporting back to a host MCU. Designers pair the BTS70202EPAXUMA1 with a small automotive MCU such as Infineon's TLE984x or TC2x family for protected, diagnosable load driving. When designing with this part, place a low-ESR 100 nF ceramic bypass capacitor directly on Vbb, follow the PCB layout recommendations in the PROFET application notes for thermal copper spreading under the exposed pad, and confirm that the configured ICL threshold leaves margin above the maximum inrush current of the specific load (e.g., cold filament lamp or motor stall). The sense resistor must be Kelvin-connected to GND to preserve current-mirror accuracy.

It combines a single N-channel MOSFET output stage with on-resistance of 0.019 Ohm and embedded protection plus diagnosis functions, providing a protected 12 V load drive path for automotive body and chassis applications. A smart high-side switch (also called an intelligent power switch or IPS) is a type of power distribution switch that sits between a microcontroller and a resistive or inductive load (lamps, solenoids, motors, LEDs). Compared with discrete MOSFETs, a smart high-side switch integrates over-current, over-temperature, over-voltage, and reverse-battery protection, plus current sense and fault feedback, dramatically simplifying the ECU wiring harness and improving ASIL-rated functional safety. Key features of the BTS70401EPAXUMA1 include a 4.5 A nominal load current, 0.019 Ohm typical on-state resistance, ReverSave capability for low power dissipation in reverse-polarity conditions, ISO 26262-ready documentation for safety-relevant systems, and AEC-Q100 Grade 1 qualification for automotive environments from -40 C to +125 C. The PROFET+2 family adds capacitive load switching, advanced short-circuit handling, and a precise analog current sense (IS pin) for load diagnostics. The device is controlled via a 3.3 V / 5 V CMOS-compatible input pin and provides detailed status feedback through both digital and analog diagnostic outputs. The integrated gate driver, charge pump, and protection logic are built on Infineon's SMART7 process, which combines a robust vertical DMOS output stage with mixed-signal control on a single die. PG-TSDSO-14 with an exposed pad enables PCB-direct thermal dissipation at the typical 1-2 W continuous load dissipation of a single automotive channel. Typical applications include automotive body electronics (door modules, seat controllers, mirror adjusters), interior and exterior LED lighting, 12 V relay and solenoid replacement, and zonal/zonal-ECU power distribution in next-generation vehicle electrical architectures. The PG-TSDSO-14 footprint supports high-density multi-channel PCBs found in BCMs and PDMs. When designing with this part, derate load current with ambient temperature using the SOA curves from the Infineon datasheet, and respect the 1.2 W continuous dissipation on the standard 2-layer 1 oz PCB footprint with the exposed pad properly soldered and via-fanned-out. The IS pin requires an external sense resistor and must be left open or pulled high when unused.

BTS70402EPGXUMA1 - 4-Channel Smart High-Side Switch | Infineon
The Infineon BTS70402EPGXUMA1 is a multi-channel smart high-side power switch from the PROFET+2 family, integrating four independent N-channel MOSFET output stages with onboard protection and diagnostics in a PG-TSDSO-14 package. Each channel delivers up to 3.5 A continuous load current from a 12 V automotive supply, with a typical on-state resistance of approximately 65 mΩ per channel that keeps conduction losses low for body-control loads. A high-side power switch (also called a smart high-side driver or PROFET) is a semiconductor device placed between the battery/load supply and the grounded load; it replaces a fuse, relay, and discrete wiring harness by providing logic-level control, inrush current limiting, short-circuit protection, and load-diagnostics feedback over a single SPI/parallel interface. Within the broader power-management hierarchy it sits at the same layer as low-side switches and eFuses, but high-side topology lets the load reference ground directly, which simplifies wiring and improves short-to-ground detection. Key features include per-channel current limiting, over-temperature shutdown with auto-restart, open-load detection both on-state and off-state, reverse-battery protection via an integrated charge pump, and ground-loss detection. The PG-TSDSO-14 small-outline package with an exposed thermal pad enables PCB designs that stay within tight under-hood and door-module area constraints while dissipating multi-watt fault power into the copper pour. The BTS70402EPGXUMA1 uses Infineon's proven PROFET vertical N-channel DMOS process with charge-pump gate drive, achieving fast switching edges and robust avalanche capability. The four channels can be paralleled for higher current loads, and the SPI-mappable status register gives the MCU real-time feedback on each output's health - essential for ASIL-B and beyond functional-safety architectures. Typical applications include automotive body-control modules (BCM), exterior lighting drivers (headlamp LED matrices, tail lamps, turn signals), seat-control and mirror-adjustment actuators, and any 12 V distributed-load system that requires replaceable-fuse behavior in solid-state form. The device's diagnostic features also suit industrial 24 V PLC outputs and agricultural/off-highway vehicle loads with similar voltage rails. When designing with this part, observe the maximum total package power dissipation and ensure the PCB thermal pad has enough copper area to keep junction temperature below 150 °C during a sustained short-circuit event; a 4-layer board with at least 2 cm² of 2 oz copper on the drain tab is a common starting point.

AEC-Q100 qualification and the wide operating voltage range make it suited to 12 V automotive body and powertrain loads, while the same robustness benefits industrial 24 V systems. Diagnostic feedback (current sense, fault flag) enables ECU load monitoring and short-to-ground/open-load detection. Typical applications include automotive body electronics (lighting, seat heating, mirror fold), relay and fuse replacement in distributed ECUs, industrial process control, and any 12-24 V system needing protected, paralleled high-side channels. The 2-channel architecture allows driving two related loads (e.g. left/right parking lamp) from one IC. When designing with the BTS70802EPAXUMA1, ensure adequate PCB copper for thermal dissipation and follow Infineon's layout guidelines for the exposed pad. Verify that the application load does not exceed 3 A continuous per channel and that the diagnostic pin (if present) is properly terminated for the ECU ADC range.

A high-side power switch is a type of smart power distribution IC that sits between a DC supply and a load (relays, solenoids, lamps, LEDs, or motors), controlling current flow via a low-voltage logic signal while protecting the load and wiring from overcurrent, overtemperature, and short-circuit conditions. In the broader product hierarchy, the BTS710336ESAXUMA1 belongs to the SPOC+2 family -> multi-channel high-side switch -> smart power distribution IC -> power management IC -> semiconductor. Key features include embedded protection functions (overload, short-circuit, overtemperature, overvoltage), configurable fault feedback through the SPI status register, and capacitive load switching capability. The exposed thermal pad enables direct PCB heat dissipation to copper pours, while the small PG-TSDSO-24-42 footprint saves board space versus discrete MOSFET solutions. Each channel provides independent diagnostic feedback including open-load detection and current sense capability. The device uses SMART7 technology, Infineon's latest-generation smart power process combining vertical DMOS output stages with on-chip analog and digital control. This architecture allows accurate current limiting, fast fault response (<10 us typical), and consistent R_DS(on) across the automotive temperature range, making the BTS710336ESAXUMA1 suitable for safety-critical body and chassis ECUs where ASIL-rated diagnostics are required. Typical applications include automotive body control modules, HVAC blower and valve drivers, LED lighting modules, and industrial PLC output modules. The combination of six independently-protected channels and SPI diagnostics reduces MCU GPIO count and enables centralized fault monitoring. When designing with this part, ensure adequate PCB copper area on the exposed pad to maintain junction temperature below 150 C at full load, and follow Infineon's SPOC+2 layout guidelines for thermal vias under the e-pad.

BTS710336ESPXUMA1 - 5-Channel 24V SPOC High-Side Switch | Infineon
The Infineon BTS710336ESPXUMA1 is a multi-channel high-side power switch from the SPOC family, integrating four 1.5A and one 3A N-channel MOSFET outputs in a single PG-TSDSO-24-42 exposed-pad package. It is a 1:5 power switch/driver designed for 12V/24V automotive and industrial loads, supporting load currents of 1.5A, 1.5A, 1.5A, 3A, and 3A across its five channels. What is a SPOC high-side switch? SPOC (Smart Power Switch) devices integrate one or more N-channel MOSFETs with diagnostic, protection, and gate-drive circuitry into a single IC, replacing discrete MOSFETs plus fuse, sense resistor, and protection circuitry. SPOC devices sit within the broader power management IC hierarchy as smart, protected high-side or low-side switches, typically used in automotive body electronics (BCM), industrial PLCs, and any system needing reliable, diagnosable load driving with built-in protection. They sit below a system-level power management IC in the abstraction stack but above discrete power MOSFETs. Key features include very low standby current, integrated reverse-battery protection with self-diagnosis, capacitive load switching capability, ground-loss robustness, and a serial peripheral interface (SPI) for configuration, channel control, and diagnostic feedback. The device operates from a wide supply range typical of 12V/24V automotive buses, and offers PWM capability for each output. On-chip protection features include over-load, over-voltage, over-temperature, and short-circuit shutdown, plus a defined restart strategy after fault clearing. Architecturally, the BTS710336ESPXUMA1 combines five independent high-side driver channels with a common SPI control block, gate drivers, charge pump, current-sense analog front end, and protection logic. The exposed pad of the PG-TSDSO-24-42 package provides a low-thermal-resistance path (PG-TSDSO denotes a power-grade TSDSO with thermal slug), essential when dissipating the power of four parallel switches on a small PCB area. Typical applications include automotive body control modules driving lighting, HVAC blowers, and seat heaters, as well as industrial PLC output modules and 24V factory-automation actuators. Its small PCB footprint makes it suitable for space-constrained, high-channel-count load driver boards. When designing with this part, ensure the exposed pad receives sufficient copper area for heatsinking and that the SPI lines are correctly pulled to the MCU's logic domain. SPI command sequencing must follow the datasheet exactly to avoid latch-up after fault events, and unused channels should be left open or tied to ground per datasheet guidance. This page synthesizes distributor pricing, drop-in pin-compatible alternatives, application context, and practical design notes not consolidated on the manufacturer datasheet, providing engineers with the information density required for first-time-right automotive or industrial 24V load-driver designs.

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.

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.

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.

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.

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.

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.
BTS80009SWPF1ESXUMA1 - 12V 34.5A Smart High-Side Switch | Infineon
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.

BTT60101ERBXUMA1 - 10mΩ Smart High-Side Switch 9A 24V/48V | Infineon
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. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes that complement the manufacturer datasheet and enable faster engineering decisions.
BTT6020-1ERA - 20mΩ Smart High-Side Switch 7A 24V | Infineon
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.
BTT60302EKAXUMA1 - 28V Dual High-Side Smart Switch | Infineon
The Infineon BTT60302EKAXUMA1 is a dual-channel, 28 V high-side power switch (PROFET) engineered for automotive and industrial load-driving applications, integrating two independent N-channel MOSFET output stages with a maximum on-state resistance of 200 mOhm per channel and a 4 A continuous load-current capability per channel. 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.
