BTS70101EPAXUMA1 Overview
A high-side N-channel MOSFET switch (also called a smart high-side driver) is a power distribution topology where the load is connected to ground and the switch sits between the battery/positive rail and the load. Compared with low-side switching, high-side drivers offer inherent short-to-ground protection, inrush-current limiting, and native compatibility with chassis-referenced vehicle loads. The PROFET+2 family targets intelligent power distribution in body and powertrain ECUs where diagnostic feedback and robust protection are mandatory.
Key features include 9 A nominal load current capability, integrated reverse-battery protection (ReverSave), embedded thermal shutdown, over-current limitation with latch behavior, open-load detection in on and off states, and proportional load-current sensing via the IS pin. Operating supply voltage spans roughly 6 V to 18 V with load-dump tolerance above 40 V, and the device is qualified to AEC-Q100 for automotive applications. The exposed thermal pad of the PG-TSDSO-14-22 package keeps junction-to-ambient thermal resistance low for continuous high-current loads.
Typical applications include automotive body controllers (BCM), HVAC blower and fan control, seat-heater and door-module drivers, LED driver front-ends, and industrial 24 V systems requiring protected switching. Designers select the BTS70101EPAXUMA1 when they need a single channel of clean, diagnosed high-side switching rather than a quad-channel low-side array. Companion devices include the BTS7120-2EPA (dual-channel) and the BTS7080-2EPA (2x 4 A) within the same PROFET+2 family for BOM reuse.
Design consideration: when laying out the PCB, dedicate a continuous copper pour under the exposed pad to the module ground, keep the IS sense trace short and shielded, and place a reverse-battery blocking diode or use the BTS7010-1EPA's ReverSave feature to meet ISO 7637-2 jump-start and reverse-polarity requirements.

Typical Applications
BTS70101EPAXUMA1 is suitable for 6 applications: Automotive Body Control Module (BCM), HVAC Blower Motor Driver, Seat Heater Load Switch, LED Front-End Driver, Door Module Sub-Driver, Industrial 24 V Protected Switch.
Automotive Body Control Module (BCM)
The BTS70101EPAXUMA1 fits automotive BCMs where one 9 A channel must drive a lighting or accessory load with full diagnostics. The 9 A continuous rating covers headlamp levellers, mirror heaters, and similar loads; the integrated IS pin reports load current back to the BCM microcontroller for short-to-ground and open-load detection per the PROFET+2 datasheet. ReverSave eliminates the external reverse-battery diode, and AEC-Q100 Grade 1 qualification removes the need for additional qualification testing at the module level.
Recommended
HVAC Blower Motor Driver
In HVAC blower control, the BTS70101EPAXUMA1's 9 A continuous rating handles a single blower stage directly while leaving thermal margin for PWM-based speed regulation. The exposed pad of the PG-TSDSO-14-22 package sinks the conduction losses into the PCB copper pour; designers add a snubber or use the device's internal slew-rate control to suppress PWM-induced EMC. IS-pin current sense enables stall detection - if the blower draws abnormal current, the BCM can shut down the channel before windings overheat.
Recommended
Seat Heater Load Switch
The BTS70101EPAXUMA1 is well matched to seat-heater resistive loads: 9 A continuous covers heating elements up to ~100 W on a 12 V system, and PWM operation through the IN pin implements closed-loop temperature control. The device's integrated overtemperature shutdown protects the seat foam and wiring harness if the heater short-circuits. ReverSave protects against service-bay jump-start mis-wiring, a common failure mode that destroys discrete MOSFET designs in seat modules.
Recommended
LED Front-End Driver
Driving automotive LED headlamp or DRL arrays from a single high-side channel is a natural fit for the BTS70101EPAXUMA1: the IS pin provides analog current feedback for closed-loop brightness regulation, and the integrated diagnostics flag open-load (LED string failure) to the BCM. The PG-TSDSO-14-22 footprint keeps the driver close to the LED PCB, reducing harness inductance. For higher LED power, parallel two BTS70101EPAXUMA1 channels with shared sense feedback.
Recommended
Door Module Sub-Driver
Door modules combine window lift, mirror adjust, and lock actuator drives; the BTS70101EPAXUMA1 is appropriate for the highest-current function such as the window motor peak current when used with PWM soft-start. The exposed pad connects to the door-module ground pour to dissipate inrush losses during motor stall events. ReverSave and load-dump tolerance (>40 V) cover the harsh door-module electrical environment without external TVS protection.
Recommended
Industrial 24 V Protected Switch
Outside automotive, the BTS70101EPAXUMA1 also serves industrial 24 V systems where protected high-side switching with diagnostic feedback is required - for example, solenoid valves, indicator lamps, or relay coils. AEC-Q100 over-qualifies the part for industrial use, but the integrated protections (overcurrent, overtemperature, open-load) reduce the BOM versus discrete solutions. The 18 V upper VBB limit means a separate variant is needed for true 24 V nominal rails; check the manufacturer's datasheet for the recommended part number.

Design Notes
Estimated: at 9 A continuous load with RDS(on) of ~10 mΩ (typical for this family), conduction loss is ~0.81 W. With PG-TSDSO-14-22 theta_JA around 50 °C/W on a 1 sq inch 2-oz copper pour, junction temperature rises ~40 °C above ambient - well within the 150 °C TJ limit. For sustained 9 A loads, dedicate the largest continuous GND copper area to the exposed pad. If operating near maximum ambient temperature, derate to 6-7 A continuous.
Solder the exposed pad (EP) to a continuous ground copper pour using at least 8 thermal vias (0.3 mm drill) to inner ground planes. Place input and load capacitors as close to the VBB and OUT pins as possible to minimize parasitic inductance that could exceed the load-dump clamp rating during jump-start pulses per ISO 7637-2. Route the IS sense trace as a short, guarded track to the ADC pin to preserve analog accuracy.
Do not leave the IN pin floating - tie it through a pull-up or pull-down resistor to a defined logic level, because the PROFET+2 family may enter an indeterminate state on floating IN. Avoid back-to-back PWM frequencies below 100 Hz on inductive loads; use a flyback or TVS clamp because the device's internal avalanche rating is limited. Never connect a DC load voltage higher than 18 V to VBB without consulting the datasheet's load-dump curve.
