BTH61002EPAXUMA1 Overview
What is a smart high-side switch? A smart high-side switch is a semiconductor relay that sits between the supply rail and the load, replacing a mechanical relay or discrete MOSFET plus fuse arrangement. It uses an N-channel MOSFET on the high side and a charge pump to drive the gate above the battery rail, allowing the load to be PWM-controlled and continuously diagnosed for open-wire, short-to-battery, short-to-ground, and overtemperature faults. These devices belong to the power distribution and power management IC hierarchy and are designed specifically for harsh automotive environments, typically qualified to AEC-Q100 and supporting load currents from a few hundred milliamps up to tens of amps.
Key features of the BTH61002EPAXUMA1 include a typical on-state resistance of 200 mOhm per channel, a 60V maximum load-dump capability, and a 54V nominal supply rating that makes it compatible with modern 48V mild-hybrid vehicle electrical systems. The device offers active-high and active-low input logic variants, precise current-sense diagnostic output for fault detection, and an adjustable current-limit function that lets the designer trade off transient surge capability against sustained fault current.
The BTH61002EPAXUMA1 uses a vertical N-channel power MOSFET architecture combined with an integrated charge pump and CMOS control logic on a single die. The PG-TSDSO-14 package with exposed thermal pad delivers a low junction-to-ambient thermal resistance, allowing sustained 2.0A per channel operation without external heatsinking. Two independent channels share a common supply pin but have separate input, output, and diagnostic pins, making the part functionally equivalent to two single-channel PROFET devices in one footprint.
Typical applications include 48V zonal architectures, 48V eBike and mild-hybrid power distribution, body control modules driving lighting and heating loads, and any automotive 48V load requiring diagnostic feedback to the ECU. It is also used in industrial 48V systems where AEC-Q100-grade robustness is desired.
When designing with this device, derate the load current with ambient temperature using the SOA curves and ensure the exposed pad is soldered to at least 1 cm² of copper for adequate thermal dissipation. The current-sense pin must be connected to a precise ground-referenced resistor to retain diagnostic accuracy.

Safe Operating Area
Typical Applications
BTH61002EPAXUMA1 is suitable for 6 applications: 48V Automotive Zonal Architecture, 48V eBike and E-Scooter Power Distribution, Automotive Body Control Module (BCM), Industrial 48V Robotics and AGV, 48V Lighting Load Switching, 48V Battery Disconnect and Load Pre-charge.
48V Automotive Zonal Architecture
The BTH61002EPAXUMA1 fits 48V zonal architectures because its 54 V nominal / 60 V load-dump rating directly matches the mild-hybrid 48V supply rail, while the 200 mOhm Ron per channel keeps conduction loss below 0.8 W at 2 A continuous. Placed between the 48V bus and each zonal load (heater, water pump, fan), it integrates the wire fuse, MOSFET, and diagnostic current sense that an ECU needs to detect partial shorts and open loads. Designers use the dual channel to drive two related loads from one device, halving PCB area versus two single-channel PROFETs.
Recommended
48V eBike and E-Scooter Power Distribution
The BTH61002EPAXUMA1 suits 48V eBike and e-scooter platforms because its 60V load-dump rating tolerates the inductive spikes of brushed DC motors and contactors common in this segment, while AEC-Q100 robustness supports outdoor temperature extremes from -40 C to +150 C. Each channel drives 2 A continuous, sufficient for headlamp, horn, brake light, and small ECU rails. The integrated current-sense output lets a small MCU implement battery-aware load shedding, extending ride time.
Recommended
Automotive Body Control Module (BCM)
The BTH61002EPAXUMA1 replaces discrete fuse-and-relay channels in body control modules with 48V rail compatibility, integrating the MOSFET, current sense, and diagnostic feedback that a BCM microcontroller needs. Its dual-channel 14-pin footprint fits the same land pattern as classic 12V PROFETs, easing migration of existing BCM designs to 48V zonal nets. The current-sense output connects directly to an ADC channel for ground-fault detection and lamp-outage diagnostics.
Recommended
Industrial 48V Robotics and AGV
The BTH61002EPAXUMA1 works in industrial 48V robotics and automated guided vehicles (AGVs) because the AEC-Q100 grade delivers proven reliability outside of road vehicles, while the 200 mOhm Ron and 2 A per channel support sensor, fan, and small actuator power distribution. The exposed-pad PG-TSDSO-14 package handles continuous operation in factory-floor ambient up to 85 C when mounted on 1 cm² of copper. The diagnostic pin enables predictive maintenance - the controller logs rising on-resistance as a wear indicator.
Recommended
48V Lighting Load Switching
The BTH61002EPAXUMA1 powers 48V LED matrix headlamps and interior lighting because it can PWM-switch the LED load at low duty cycles for dimming while the integrated current-sense output provides a closed-loop feedback signal to the lighting ECU. The 60V load-dump tolerance handles the alternator pulse events that 48V LED drivers must survive. Two channels in one footprint let one device drive high-beam and low-beam separately.
Recommended
48V Battery Disconnect and Load Pre-charge
The BTH61002EPAXUMA1 functions as a secondary load-disconnect switch in 48V battery management because its 60V rating covers the worst-case transient during pre-charge of large DC-link capacitors, and the diagnostic output verifies successful load connection. While not a primary contactor replacement (use a mechanical relay or contactor for full 200+ A disconnect), the BTH61002EPAXUMA1 handles downstream sub-2 A subsystems safely with full diagnostic feedback to the BMS.

Key Differentiators
- 48V automotive board-net rating (vs BTS70402EPGXUMA1)
- Dual-channel integration in one package (vs BTH60801EPLXUMA1)
- PROFET + 48V family advanced diagnostics (vs ISP752TFUMA1)
Design Notes
At continuous 2.0A per channel and 200 mOhm Ron, the BTH61002EPAXUMA1 dissipates approximately 0.8W per channel (1.6W total for both channels). The PG-TSDSO-14 exposed thermal pad must be soldered to at least 1 cm² of inner-layer copper with multiple thermal vias to the bottom layer. At 85 C ambient, without this copper, the junction temperature can exceed 150 C and trigger thermal shutdown - the exposed pad is not optional.
Do not connect a 12V-rated PROFET (BTS70402EPGXUMA1, BTS710336ESAXUMA1, BTS51202EKAXUMA1, ISP752TFUMA1) as a drop-in replacement on a 48V rail - their voltage rating is ~28V max and the device will fail destructively during load-dump. The PG-TSDSO-14 footprint is shared across Infineon's PROFET families, but voltage classes are NOT pin-compatible. Always verify the voltage rating in the type designation before substitution.
Place a 100nF X7R ceramic bypass capacitor directly between VS and GND, within 5mm of the device pins, to absorb the charge-pump switching noise. Add a TVS diode (e.g. SMBJ54A) on VS to clamp 48V load-dump pulses above 60V. Route the IS current-sense trace as a Kelvin connection to a precision ground-referenced resistor (1% tolerance or better) to retain diagnostic accuracy within +/-10% across the operating range.
