BTS4130QGAXUMA1 개요
A high-side power switch (also called a smart high-side driver) is a semiconductor switch placed between the positive supply rail and the load, controlling current flow with low-side referenced logic. Within the broader IC hierarchy, it sits in the power management family alongside low-side switches, half-bridge drivers, and H-bridges, and is specifically engineered to replace electromechanical relays and discrete MOSFET circuits in body-electronics, lighting, and heating modules. The BTS4130QGA family uses N-channel MOSFETs with an internal charge pump rather than P-channel devices, giving lower R_DS(on) per silicon area and tighter current-limit accuracy.
Key features include per-channel current limiting, overtemperature shutdown with auto-restart, overvoltage clamp (load-dump robust to 45 V), reverse-battery protection via an intrinsic body diode, ground-loss robustness, and a status feedback pin for fault indication to the MCU. The device operates from a 6 V to 18 V supply (extended range up to 28 V transient) and is qualified to AEC-Q100 for automotive use.
Typical applications include driving automotive lamps up to 2.1 A per channel, relay replacement in body control modules, solenoid and small-motor drivers, and resistive heating elements. The quad-channel integration lets one IC replace four discrete high-side switches, reducing PCB area and BOM cost.
When designing in this part, ensure the heatsink copper area is sized to keep junction temperature below 150 C at the worst-case ambient and per-channel load, and always include reverse-battery protection at the module input. Compared with discrete N-MOSFET + gate-driver solutions, the BTS4130QGA eliminates gate-drive design complexity and provides diagnostic feedback out of the box.

일반적인 애플리케이션
BTS4130QGAXUMA1 적합 용도: 6 애플리케이션s: Automotive Body Control Modules, Automotive LED Lighting Drivers, Relay Replacement in Automotive ECUs, Solenoid and Small DC-Motor Drivers, Resistive Heating Elements, Industrial 24 V PLC Discrete Outputs.
Automotive Body Control Modules
The BTS4130QGAXUMA1 drives up to four 12 V loads from a single BCM, replacing four discrete high-side MOSFET circuits and four fuses. Each 2.1 A channel can independently switch lamps, solenoids, or relay coils, while the 45 V load-dump clamp and reverse-battery protection handle the harsh 12 V automotive bus. According to the Infineon datasheet, the status feedback pin reports short-to-ground, open-load, and overtemperature faults back to the BCM microcontroller for OBD-II diagnostics. Compared with electromechanical relays, this quad switch reduces PCB area by approximately 70% and eliminates audible relay click and contact bounce.
추천
Automotive LED Lighting Drivers
The BTS4130QGAXUMA1 is well suited to drive LED daytime running lights, position lamps, and turn indicators up to 2.1 A per channel. Its high 2.1 A rating allows paralleling two channels for higher-current LED matrices, while the 130 mOhm R_DS(on) keeps conduction losses below 0.6 W at full load - simplifying thermal design on the PCB. According to Infineon's PROFET+ application notes, PWM dimming at 200 Hz is supported via the INx logic pins for DRL brightness control. The integrated overcurrent and overtemperature protection prevents LED-string short failures from damaging the wiring harness.
추천
Relay Replacement in Automotive ECUs
Engineers replace 12 V automotive relays with the BTS4130QGAXUMA1 to gain silent switching, longer lifetime, and built-in diagnostics. Four relay coils up to 2.1 A each fit on one chip, with the logic-level INx pins driven directly from a 3.3 V or 5 V microcontroller - no level shifters required. According to Infineon's PROFET datasheet, the device's inherent reverse-battery capability eliminates the external Schottky diode that discrete MOSFET designs require. Lifetime exceeds 1 million cycles vs typical mechanical relay 100k cycles, dramatically improving ECU reliability.
추천
Solenoid and Small DC-Motor Drivers
The BTS4130QGAXUMA1 drives 12 V DC solenoids, valves, and small DC motors up to 2.1 A per channel in body-electronics applications. The integrated inductive-load clamp handles the back-EMF of de-energizing solenoids, protecting both the switch and the harness from voltage transients. According to the Infineon datasheet, the 2.1 A current limit can be derated to match specific solenoid pull-in and hold currents. The status pin reports stall conditions when a DC motor draws abnormal current, useful for window-lifter and seat-positioner diagnostics.
추천
Resistive Heating Elements
For heated seats, steering wheels, and mirror defrosters drawing up to 2.1 A at 12 V, the BTS4130QGAXUMA1 provides four independently PWM-controlled heating channels from one IC. The low 130 mOhm R_DS(on) keeps dissipation manageable, while the status pin signals open-circuit (broken heating wire) faults to the climate-control ECU. According to Infineon's PROFET+ family documentation, the wide 6-18 V operating range tolerates cranking transients when multiple heaters switch simultaneously. Compared with discrete N-MOSFET designs, the integrated thermal protection prevents fire hazards if a heater short-circuits.
추천
Industrial 24 V PLC Discrete Outputs
Outside automotive, the BTS4130QGAXUMA1's 28 V transient rating makes it usable as a quad 24 V PLC digital output module, switching loads up to 2.1 A per channel. The PROFET family provides galvanic-isolation-friendly logic inputs and diagnostic feedback over the same harness as the load wires. According to the Infineon datasheet, the wide operating range and reverse-battery protection suit industrial cabinet environments with inductive load switching. The PG-DSO-20-32 package is suitable for both through-hole and SMT industrial board assemblies.

주요 차별점
- Quad-channel integration in PG-DSO-20 (vs ITS4142NHUMA1)

설계 노트
Estimated: At 2.1 A continuous per channel with VIN=14 V and VOUT=load, dissipation per channel = 2.1 A^2 x 130 mOhm = 0.57 W. With 4 channels active worst-case = 2.28 W. The PG-DSO-20-32 has typical theta_JA around 50 C/W on standard JEDEC EIA/JESD51 2s2p board, so junction rise = ~114 C - adequate for 85 C ambient but requires PCB copper area enlargement (thermal pad) for 105 C automotive ambient.
Place the BTS4130QGAXUMA1 close to the connector to minimize load-loop inductance and radiated EMI. Use wide copper pours for Vbb and GND pins (at least 100 mil wide) to support the 8.4 A peak combined current. According to the Infineon PROFET+ datasheet, exposed copper beneath the package significantly reduces junction temperature - allocate at least 1 cm^2 of 2 oz copper for reliable operation above 2 A per channel.
Do not connect inductive loads (relay coils, solenoids, DC motors) without verifying the internal inductive clamp is adequate. According to the Infineon datasheet, all four outputs have integrated active clamping, but energy dissipation during clamp must be checked - repetitive clamp events can thermally overload the device. Always add a reverse-battery protection diode or MOSFET at the module Vbb input if the harness can see reverse polarity during service.
