Typical Applications
BTS500801TEAAUMA1 is suitable for 6 applications: Automotive Headlamp and Tail Lamp Driver, 12 V Relay and Solenoid Replacement, Interior LED Lighting Module Driver, Automotive Body Control Module (BCM) Load Driver, Industrial 24 V Actuator and Valve Driver, 12 V Heated Seat and Mirror Heater Driver.
Automotive Headlamp and Tail Lamp Driver
The BTS500801TEAAUMA1's 10 A continuous load current and 28 V load-dump tolerance make it ideal for direct drive of automotive headlamp and tail lamp bulbs. Its 10 milliohm typical RDS(on) limits steady-state conduction loss to roughly 1 W at full load, which the PG-TO252-5-11 drain tab can dissipate on standard FR4 copper. The integrated IS pin allows the BCM (body control module) to detect open-filament and short-to-ground faults without a separate shunt, replacing the legacy relay + fuse + wiring harness with a single semiconductor switch. Reverse-battery protection up to -28 V eliminates the inline diode typically required for bulb protection.
Recommended
12 V Relay and Solenoid Replacement
The BTS500801TEAAUMA1 directly replaces mechanical relays in 12 V body electronics applications such as door locks, seat adjusters, and mirror heaters. With integrated current limiting and active clamp, it absorbs the inductive kick from solenoid coils at turn-off without external freewheeling diodes, reducing PCB area and BOM cost. The IS pin provides closed-loop current monitoring for stall detection in motorized seat applications, while the wide 4.5 V to 28 V operating range handles cranking transients down to 6 V and load-dump spikes up to 28 V common in automotive electrical systems.
Recommended
Interior LED Lighting Module Driver
For interior ambient lighting and LED reading lamps, the BTS500801TEAAUMA1 provides PWM-able high-side drive with millisecond response time, allowing brightness control via direct microcontroller PWM at 100-200 Hz without external gate drivers. The 10 milliohm RDS(on) keeps conduction losses negligible even at typical LED string currents of 1-3 A, and the diagnostic IS pin can detect LED open-circuit failures for lamp-out indication required by automotive safety standards. The PG-TO252-5-11 footprint fits compact LED driver PCBs and dissipates the modest IΒ²R losses without heatsinking.
Recommended
Automotive Body Control Module (BCM) Load Driver
The BTS500801TEAAUMA1 serves as a building block in BCMs, where multiple high-side switches control exterior lamps, horn, wipers, and accessory loads from a single ECU. The device's diagnostic IS output enables per-channel fault reporting back to the BCM microcontroller, supporting OBD-II lamp-out detection required by FMVSS and ECE regulations. With 10 A continuous rating per channel and 28 V load-dump survival, the BTS50080-1TEA family can drive most 12 V body loads directly, eliminating the discrete MOSFET + driver + TVS + shunt resistor circuit in each channel.
Recommended
Industrial 24 V Actuator and Valve Driver
Although nominally a 12 V PROFET, the BTS500801TEAAUMA1's 28 V maximum supply rating allows operation on industrial 24 V systems with adequate derating. It drives solenoid valves, small pneumatic actuators, and 24 V relay coils with the same protections as in 12 V automotive use: over-current, over-temperature, and active clamp for inductive loads. The 4-pin DPAK footprint is widely supported by industrial PCB assembly lines, and the IS pin supports predictive maintenance by reporting actuator current back to the PLC for stuck-valve detection.
Recommended
12 V Heated Seat and Mirror Heater Driver
The BTS500801TEAAUMA1 drives resistive heating loads such as seat heaters and exterior mirror heaters, where currents of 5-10 A are typical for fast warm-up. Its integrated current limit protects against heater-element shorts to ground, a critical safety function in seat applications. The diagnostic IS pin allows the climate-control module to detect heater failures and disable the channel. The PG-TO252-5-11 drain tab, when soldered to a 1 square inch copper pour, sustains continuous 10 A operation with junction temperature rise well within the 150 C rating under seat-cushion ambient conditions.

Key Differentiators
- Same package and pinout as the entire BTS50080-1TEA family (vs BTS500801TEBAUMA1)
- 10 A continuous current in the standard PROFET 12V family (vs BTS500551TMBAKSA1)
- 28 V load-dump tolerance vs 16 V on cross-brand equivalents (vs VN5E016MH-E)
Design Notes
Estimated thermal analysis: at 10 A continuous load with 10 milliohm RDS(on), the device dissipates roughly 1 W (IΒ² x R = 10Β² x 0.01). The PG-TO252-5-11 package's drain tab should be soldered to a PCB copper pour of at least 1 square inch (approximately 6 cmΒ²) on the top or bottom layer to keep junction temperature rise within 50 C above ambient. Without sufficient copper, RDS(on) increases with temperature and the part may not sustain 10 A continuously. For high-ambient (>85 C) under-hood applications, use multiple thermal vias under the tab to spread heat to inner copper planes.
Place the device's drain tab on a copper pour connected to the load output; the drain tab is internally the drain node of the MOSFET. Keep the high-current load trace wide (at least 0.1 inch / 2.5 mm per ampere) and short to minimize parasitic inductance that could cause voltage ringing during PWM switching. The IS pin trace should be kept away from the IN/OUT switching traces to avoid capacitive coupling that distorts the sense current signal.
Do not connect the IS pin directly to a microcontroller ADC input - always use an external sense resistor to ground. The IS pin sources current (it is not a voltage output); attempting to read it with a high-impedance ADC without a sense resistor will produce undefined readings. Also, verify the IS pin's sense ratio (typically 1:5000 to 1:10000) from the datasheet before designing the fault-detection thresholds, as the ratio varies with junction temperature and load current. Reverse-battery protection is integrated, but do not exceed -28 V on the IN pin.
For PWM dimming of LED loads, switch the device at frequencies between 100 Hz and 1 kHz to avoid audible noise while maintaining good dimming resolution. The IS pin can be used to implement closed-loop current regulation by reading the sense voltage, computing the load current, and adjusting the PWM duty cycle accordingly - this compensates for LED forward-voltage variation with temperature. Place a 100 nF decoupling capacitor close to the IN pin to suppress supply transients during switching.
