BTS6143DAUMA1 Descripción general
A smart high-side switch, also known as an Intelligent Power Switch (IPS) or PROFET, is a power distribution IC that places a protected MOSFET between the battery/load supply and the load. Compared with discrete MOSFETs plus fuses, an IPS replaces the fuse, the relay, and the protection circuitry with one monolithic device, reducing PCB area while adding diagnostic feedback (current sense, fault flag, temperature sense) to the microcontroller.
Key features include short-circuit protection with latch, current limitation, overload protection, thermal shutdown with auto-restart, overvoltage protection including load-dump transients, loss-of-ground protection, and loss-of-Vbb protection. The integrated charge pump drives the gate of the vertical N-channel power MOSFET, achieving low R_DS(on) per unit silicon area and minimizing conduction loss at 12 V nominal rails.
Typical applications are automotive body-electronics loads such as lighting modules (headlamp, fog lamp, tail lamp), seat heating, window lift, wiper motors, and other resistive or inductive 12 V actuators. The 5-pin DPAK footprint provides a thermal pad that simplifies heatsinking to the PCB copper pour for sustained high-current operation.
When designing with this part, ensure the PCB copper area beneath the exposed tab meets Infineon's recommended footprint and thermal pattern. Verify that the diagnostic pins are correctly pulled to interface with the host MCU's ADC or logic inputs, and that the load is properly clamped against inductive kickback to stay within the device's SOA.

Aplicaciones típicas
BTS6143DAUMA1 es adecuado para 6 aplicacións: Automotive Front and Rear Lighting, Seat Heating and HVAC Blower Control, Power Window Lift and Sunroof Drive, Wiper Motor and Washer Pump Driver, Industrial 24 V Solenoid and Valve Control, Auxiliary 12 V Power Outlet Switching.
Automotive Front and Rear Lighting
The BTS6143DAUMA1's ~8 A continuous rating and integrated short-circuit plus open-load diagnostics make it well suited to driving headlamp, fog-lamp, and tail-lamp LED modules directly from a 12 V battery rail. According to Infineon Classic PROFET application guidance, the device's diagnostic pin feeds fault status back to the BCM (body control module) over a single-wire IS interface, enabling the BCM to detect lamp-out and short-to-GND conditions without external sense resistors. Compared with a discrete MOSFET + fuse solution, the integrated thermal shutdown and overvoltage (load-dump) protection reduce PCB component count and eliminate the fuse replacement service event for automotive OEMs.
Recomendado
Seat Heating and HVAC Blower Control
The BTS6143DAUMA1 is a standard choice for resistive seat-heater mats and HVAC blower loads in 12 V vehicle electrical systems. Its current-limit and overload-protection thresholds are tuned to fold back safely on a stalled blower motor or a folded seat-heater element, while the loss-of-ground and loss-of-Vbb protections prevent back-feeding the harness if the load ground is lost. According to the manufacturer datasheet, the device's thermal-shutdown-with-restart behavior allows automatic recovery after the fault clears, which is critical for passenger-comfort loads that must resume operation without a service visit.
Recomendado
Power Window Lift and Sunroof Drive
Driving a 12 V DC motor for a power window or sunroof demands high inrush current handling plus robust inductive kickback clamping - both of which the BTS6143DAUMA1 addresses through its integrated MOSFET and protection set. The classic PROFET datasheet notes that the device can sustain motor stall currents while the overload-protection timer allows time for the motor to start under load. For H-bridge reversing applications, two BTS6143DAUMA1 devices can be used as a half-bridge, with the diagnostic outputs providing stall detection feedback to the door-module MCU.
Recomendado
Wiper Motor and Washer Pump Driver
The BTS6143DAUMA1's ~8 A continuous rating and short-circuit-with-latch behavior make it appropriate for driving windshield wiper motors and washer pumps from a 12 V body controller. According to Infineon application guidance, the integrated overvoltage clamp protects against the load-dump transients typical when the wiper stalls at end-of-travel, while the diagnostic output flags a jammed motor so the BCM can command a parking maneuver. Compared with electromechanical relays, the BTS6143DAUMA1 eliminates audible click noise and provides silent PWM speed control when paired with a low-frequency dimming signal.
Recomendado
Industrial 24 V Solenoid and Valve Control
Outside the automotive segment, the BTS6143DAUMA1 can drive 24 V industrial solenoid valves and pneumatic actuators as long as the load current stays below the device's ~8 A rating. The loss-of-ground and loss-of-Vbb protections, originally designed for automotive harnesses, also provide resilience against field wiring faults common in factory environments. According to Infineon, designers should add an external TVS clamp for 24 V inductive loads to keep the OUT pin within the device's SOA during turn-off transients.
Recomendado
Auxiliary 12 V Power Outlet Switching
The BTS6143DAUMA1 is well matched to switched 12 V cigarette-lighter-style power outlets in passenger compartments, where the integrated short-circuit and overload protection eliminates the fuse box and reduces warranty events. According to the manufacturer datasheet, the diagnostic pin allows the BCM to report an overloaded outlet to the dashboard and disable it before the wiring harness overheats. Compared with a fused discrete MOSFET design, the BTS6143DAUMA1 provides self-resetting protection and live fault feedback without service intervention.

Diferenciadores clave

Notas de diseño
Estimated: at 12 V Vbb, ~1 V drop across the MOSFET at 8 A load, the BTS6143DAUMA1 dissipates ~8 W. The PG-TO252-5-11 exposed tab requires a minimum 100 mm-squared 2 oz copper pour on the top layer plus thermal vias to the inner plane to keep Tj below 150 C. Without adequate copper, the device will enter thermal shutdown under sustained 8 A loads at 25 C ambient.
Per Infineon Classic PROFET layout guidelines, place a 100 nF decoupling capacitor as close as possible to the Vbb pin to suppress load-dump transients and high-frequency switching noise. The exposed tab must be soldered to a copper pad that is the same net as OUT (not floating), and the diagnostic pin trace should be kept short and away from switching-node traces to avoid capacitive coupling into the IS sense path.
Do not connect the BTS6143DAUMA1's OUT tab to GND - the tab is internally connected to the drain of the high-side MOSFET and must be treated as the switched output net. A common PCB error is treating DPAK-5 the same as DPAK-3, leading to a short-to-ground. Also verify that inductive kickback from relays or motors is clamped by an external free-wheeling diode or TVS, since the BTS6143DAUMA1's internal avalanche rating is intended for short transients only.
