BTS711L1XUMA1 Overview
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.

Typical Applications
BTS711L1XUMA1 is suitable for 6 applications: Automotive Body Control Module (BCM), 12 V Automotive LED Lighting, Relay and Solenoid Replacement, Industrial 24 V PLC Output Module, Heated Seat and Steering Wheel Control, Power Distribution Node with Diagnostics.
Automotive Body Control Module (BCM)
The BTS711L1XUMA1 is a natural fit for automotive body control modules where four 12 V loads such as door lock motors, mirror fold actuators, seat adjustment relays, or interior lighting must be switched and diagnosed from one compact IC. With 1.7 A per channel and the 43 V load-dump clamp it directly meets ISO 7637-2 requirements, eliminating external TVS components. The current-sense output feeds the BCM microcontroller so fault conditions (open load, short to battery, short to ground, overtemperature) are reported via OBD or body-domain CAN. Recommended companion MPNs: BTS710336ESAXUMA1 (3-channel variant for asymmetric loads), BTS70402EPGXUMA1 (2-channel high-current variant), and the TLE94110ESXUMA1 multi-half-bridge driver for motor-direction loads.
Recommended
12 V Automotive LED Lighting
Driving 12 V LED strings for tail lamps, daytime running lights, turn indicators, and interior ambient lighting is a sweet spot for the BTS711L1XUMA1. Each of the four channels can PWM-modulate a separate LED string up to the device's PWM capability, while integrated overtemperature and open-load detection protects against LED failure modes common in automotive environments. The low R_DS(on) of 200 mΩ per channel keeps conduction losses minimal, and the 43 V clamp protects against load-dump events triggered when the alternator field collapses. Companion parts include the BTH62004ESAXUMA1 half-bridge for combined high/low-side LED driving and the TLD23313EPXUMA1 LED driver for constant-current applications.
Recommended
Relay and Solenoid Replacement
The BTS711L1XUMA1 replaces electromechanical relays and discrete MOSFET-plus-flyback-diode circuits used to drive 12 V solenoids, valves, and latching relays in industrial and automotive systems. Each channel's fast demagnetization circuit safely handles the inductive kickback from coil energization, while the integrated 43 V clamp absorbs the transient without external freewheeling diodes. Replacing four relays with one PG-DSO-20-31 IC reduces PCB area by typically 70%, eliminates audible relay click, removes mechanical wear, and adds diagnostic feedback so a stuck solenoid or open coil can be reported to the host controller. The BTS70402EPGXUMA1 (2-channel, higher current) is recommended when individual loads exceed 2 A.
Recommended
Industrial 24 V PLC Output Module
Although designed for 12 V automotive use, the BTS711L1XUMA1 can serve in 24 V industrial PLC output modules driving lamps, contactors, and small actuators, because the 28 V operating ceiling and 43 V clamp tolerate 24 V nominal bus transients. Each channel's current-sense output enables per-channel load monitoring, allowing the PLC firmware to detect wire-break, short-circuit, or overload conditions and report them through the fieldbus. The PG-DSO-20-31 package's exposed thermal pad simplifies mounting on the PLC module's aluminum heatsink or copper pour. Companion Infineon parts for adjacent functions include the 1ED020I12B2XUMA1 gate driver and the IRS2110SPBF for higher-side driving of external MOSFETs.
Recommended
Heated Seat and Steering Wheel Control
Heated seats and steering wheels are typically driven by N-channel MOSFETs in high-side configuration with PWM to regulate heating element power. The BTS711L1XUMA1 integrates four such high-side switches plus protection, so a single IC can drive seat-cushion, seat-back, left steering-wheel, and right steering-wheel heating elements with independent PWM control. The 1.7 A per channel rating is more than adequate for typical 50-100 W heating loads, and the integrated thermal shutdown protects against blocked ventilation or shorted heating mats. Diagnostic feedback informs the body controller of an open heating element, allowing end-of-line test and warranty analytics.
Recommended
Power Distribution Node with Diagnostics
The BTS711L1XUMA1 functions as a smart power distribution node in modular 12 V architectures, replacing four fuse-and-switch branches with one diagnostic-aware IC. Each channel's current-sense pin lets the host microcontroller measure load current continuously, enabling closed-loop control of lighting brightness, motor speed, or heater temperature without an additional shunt resistor. The diagnostic IS pin distinguishes between open load, short to ground, short to battery, and overtemperature, which is critical for functional-safety (ISO 26262) applications where fault mode coverage must be demonstrated. The PG-DSO-20-31 footprint allows placement close to the load connector, minimizing wire harness length and reducing EMC emissions.

Design Notes
Estimated: with all four channels driving 1.7 A simultaneously and R_DS(on) = 200 mΩ per channel, each channel dissipates approximately 0.58 W, totaling 2.3 W package dissipation. The PG-DSO-20-31 exposed thermal pad must be soldered to at least 1 square inch of copper on the top or bottom PCB layer to keep junction temperature rise within safe limits; without this, the device will enter thermal shutdown under full 4-channel load. Refer to Infineon's PROFET™ application note for copper-area derating curves.
Place the external R_GND resistor(s) (2 × 150 Ω or 1 × 75 Ω) as close as possible to the GND/R_GND pins to minimize parasitic inductance, which can compromise reverse-battery protection and current-sense accuracy. Use wide copper pours on Vbb pins (1, 10, 11, 12, 15, 16, 19, 20) since they are all bonded to the same leadframe; insufficient Vbb copper can cause voltage drops during load-dump clamping. Decouple Vbb with at least 100 nF ceramic plus 10 µF electrolytic within 5 mm of the package.
Do not connect the BTS711L1XUMA1 directly to chassis ground without the R_GND resistors; reverse-battery protection will not function and the internal ESD structures may be damaged. Avoid PWM frequencies below 100 Hz on inductive loads because the demagnetization circuitry may not have enough time to fully recirculate coil energy between cycles. The IS (current-sense) output is current-mode, not voltage-mode - always use a sense resistor to GND and reference it correctly to your ADC, never connect IS directly to a microcontroller input without the proper interface network shown in the datasheet.
