BTS500801TEAAUMA1 Overview
A high-side switch (also called a high-side driver) is a semiconductor switch placed between the positive supply rail and the load, in contrast to a low-side switch that sits between the load and ground. Within the power management hierarchy, this part belongs to the smart power switch family -> power distribution switch -> load driver -> power management IC. Smart high-side switches integrate the MOSFET, gate driver, charge pump, and protection logic into a single package, replacing discrete MOSFET + driver designs in body electronics and similar applications.
Key features include a 12 V nominal operating supply (4.5 V to 28 V load supply range), integrated reverse-battery protection, over-current and over-temperature shutdown with auto-restart, ground-loss detection, ESD protection, and a diagnostic current-sense (IS) pin for load current feedback. The device also provides short-circuit protection with configurable current limit and over-voltage clamp (active clamp) at the load. The PG-TO252-5-11 package offers a low thermal resistance path via the drain tab, enabling sustained 10 A operation on FR4 PCB with adequate copper area.
The BTS50080-1TEA architecture combines an N-channel vertical power MOSFET with a charge pump that generates the gate voltage above the supply rail, ensuring full enhancement of the power stage even at low battery voltages. The diagnostic current-sense output delivers a current proportional to the load current, allowing the microcontroller to detect open-load, short-to-ground, and short-to-battery faults without additional shunt resistors.
Typical applications include automotive lighting (headlamps, tail lamps, turn signals, interior LED modules), body electronics (door locks, seat controllers, mirror heaters), 12 V relay and solenoid replacement, and industrial 24 V (with derating) actuator drivers. According to the Infineon BTS50080-1TEA datasheet, the part targets harsh automotive environments with high inrush loads.
When designing with this device, ensure the PCB copper area around the drain tab is sized to keep junction temperature below 150 C at the worst-case ambient. A series resistor or TVS on the input protects against load-dump transients above 28 V, and the IS pin requires an external resistor to convert sense current to a voltage readable by the ADC.

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.

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.
