BTS500201TADATMA1 Overview
A high-side power switch is a semiconductor device that connects a load (such as a lamp, solenoid, relay coil, or motor winding) to the positive supply rail and is controlled by a low-voltage logic-level signal on its input pin. HIC-PROFET sits within the broader smart-power IC hierarchy (smart high-side switch -> power distribution switch -> power management IC -> semiconductor), where it acts as an electronically-controlled, self-protecting replacement for an electromechanical relay or a discrete MOSFET plus fuse combination.
Key features include a nominal 13.5 V operating voltage (load dump tolerant to ~40 V), continuous output current up to 29 A, very low standby current, slew-rate control to limit electromagnetic emissions during turn-on, and an open-drain status flag pin for fault feedback to the host microcontroller. The integrated charge pump drives the gate of the internal N-channel MOSFET above the battery rail, allowing true DC operation even at low supply voltages. Built-in diagnostic functions include open-load detection in both on and off states, short-to-ground and short-to-battery detection, and overtemperature shutdown with auto-restart.
Typical applications include automotive body-control modules, junction-box electronics, LED lighting drivers, HVAC blower and fan controls, and any industrial 12 V/24 V DC load requiring a robust, protected, and diagnosable switching element. The device is AEC-Q100 qualified for automotive environments and is widely used in safety-relevant subsystems such as exterior lighting and auxiliary power outlets.
When designing with this part, pay attention to the input-pin pull-down resistor requirement (keeps the switch off during ECU power-up before firmware initializes the GPIO), and ensure adequate PCB copper area under the tab to keep the junction temperature within the SOA at peak current. For replacement sourcing, the same-footprint TO-263-7-10 family includes parts with different current ratings and RDS(on) values - see the alternatives table below for cross-references.

Typical Applications
BTS500201TADATMA1 is suitable for 6 applications: Automotive Body-Control Module, LED Lighting Driver (Exterior Lighting), HVAC Blower and Fan Control, Industrial 24 V Solenoid and Valve Control, Auxiliary 12 V Power Outlet, Relay Replacement (Solid-State Switching).
Automotive Body-Control Module
The BTS500201TADATMA1 fits automotive BCMs because its 29 A continuous rating comfortably drives door-lock actuators, exterior mirrors, and seat-adjustment motors from the 12 V body-electronic bus. According to the Infineon datasheet, AEC-Q100 qualification and built-in slew-rate control reduce EMC re-engineering while the open-drain status flag returns load-failure diagnostics to the BCM microcontroller. Placed between the battery rail (after the reverse-polarity protection diode) and the load connector, it replaces a relay plus fuse and frees board area; the exposed tab requires ~1 sq inch of copper pour to keep Tj within SOA at peak inrush.
Recommended
LED Lighting Driver (Exterior Lighting)
Headlamps, tail lamps, and turn-indicator LED modules benefit from the BTS500201TADATMA1's 13.5 V nominal operation, slew-rate-limited turn-on, and short-to-ground detection. The device directly drives high-brightness LED strings via PWM from a logic-level GPIO, with the integrated charge pump ensuring full RDS(on) even at low cranking voltages during cold-start. Estimated: at 24 W LED load, dissipation is roughly 0.3 W at 12.5 V, well within the thermal envelope of the TO-263-7-10 tab on 1 sq inch of copper.
Recommended
HVAC Blower and Fan Control
HVAC blower motors draw tens of amps at 12 V and the BTS500201TADATMA1's 29 A continuous rating covers inrush surges that blow electromechanical relays. Its current-limit and overtemperature shutdown with auto-restart protect the switch from stall-current events, while the status flag signals the HVAC ECU to enter a fault mode. According to the Infineon HIC-PROFET datasheet, slew-rate control limits the di/dt that would otherwise couple into adjacent sensor harnesses.
Recommended
Industrial 24 V Solenoid and Valve Control
Industrial solenoid valves, hydraulic actuators, and pneumatic valves running on a 24 V bus are a drop-in use case for the BTS500201TADATMA1 because of its wide operating range and integrated protections. Replacing discrete FETs plus fuses reduces wiring faults, and the diagnostic pin lets a PLC detect open coils without external sense resistors. Estimated: a 24 V, 1 A solenoid dissipates ~24 W during switching, but steady-state losses on the switch itself are < 0.1 W at full conduction.
Recommended
Auxiliary 12 V Power Outlet
Cigarette-lighter and accessory-power outlets in vehicles routinely see abusive loads (dead shorts, sustained overload) and benefit from the BTS500201TADATMA1's full set of self-protections. According to the Infineon datasheet, the part survives short-to-ground, short-to-battery, and reverse-battery events without external fusing in many designs, simplifying the harness and the bill of materials. The status flag returns fault state to the BCM for service-diagnostic codes.
Recommended
Relay Replacement (Solid-State Switching)
Across industrial and automotive subsystems, the BTS500201TADATMA1 replaces mechanical relays to eliminate coil drive, contact bounce, and arcing, while adding telemetry. Drop-in compatibility with TO-263-7-10 footprint means existing relay-driver boards can be modernized with no PCB change. The exposed tab doubles as both thermal relief and chassis-ground bond, helping EMI on long cable harnesses.

Design Notes
The PG-TO-263-7-10 tab is the primary heat-dissipation path. Estimated: at 29 A continuous and RDS(on) of ~8 mΩ, conduction loss is ~6.7 W; without at least 1 sq inch of 2 oz copper on the tab, junction temperature will exceed 150 °C. For sustained high-current operation, consider active airflow or attach a stamped aluminum heatsink to the tab.
Use a star-ground topology on the power board, with the BTS500201TADATMA1's GND pin returned to the same ground point as the load current return. Place the input-pin pull-down (typically 10–100 kΩ) as close as possible to the device to prevent false turn-on during ECU reset. Keep the status-pin trace away from switching-output traces to avoid capacitive coupling into the diagnostic path.
Do not exceed the published load-dump and jump-start voltage limits; even with internal clamping, sustained over-voltage destroys the bond wires. Do not parallel multiple BTS500201TADATMA1 devices for higher current - they lack active current sharing. Always check the input-pin logic thresholds against your MCU's GPIO levels at cold temperatures, where thresholds can shift by 100 mV or more.
Keep the high-current output loop (VBB → internal FET → OUT → load → GND) as tight as physically possible to minimize parasitic inductance, which otherwise causes voltage spikes on the OUT pin during turn-off. Per Infineon HIC-PROFET application notes, route the status-pin trace as a guarded net, and add a small RC snubber (≈100 Ω + 100 nF) only if ringing at the OUT pin exceeds 30 V.
