Typical Applications
BTT60302ERAXUMA1 is suitable for 6 applications: Automotive Body Control Module (BCM), 24V Truck and Commercial Vehicle Power Distribution, Resistive and Inductive Load Driving, Automotive Lighting Drivers, Industrial 24V Power Distribution, Smart Fuse / Electronic Circuit Protection.
Automotive Body Control Module (BCM)
The BTT60302ERAXUMA1 is purpose-built for automotive body control modules that drive lamp, solenoid, and small-motor loads from a 12 V battery rail. Its dual 4 A channels in PG-TDSO-14-31 halve PCB area versus two single-channel switches, while the 32 mΩ Rds(on) keeps conduction losses below 0.5 W per channel at full load, so no external heatsink is needed. AEC-Q100 qualification covers the -40 °C to +150 °C junction range required for under-dash and under-hood body modules.
Recommended
24V Truck and Commercial Vehicle Power Distribution
For 24 V commercial-vehicle power rails, the BTT60302ERAXUMA1 operates across 8 V to 36 V with 42 V load-dump tolerance, covering both 12 V jump-start and 24 V nominal truck electrical systems. Its dual-channel architecture suits marker-lamp, headlamp-leveling, and trailer-interface loads where two protected outputs share a common diagnostic bus. Compared with discrete MOSFET + fuse designs, the integrated IS pin cuts BOM cost and PCB area while adding MCU-readable fault detection.
Recommended
Resistive and Inductive Load Driving
Driving resistive loads (heaters, PTC warmers) and inductive loads (valves, small solenoids) requires robust demagnetization handling. The BTT60302ERAXUMA1's integrated charge pump fully enhances the N-channel MOSFET down to 8 V supply, and the Smart6 technology includes inductive-load clamp protection. The 32 mΩ Rds(on) keeps thermal rise under 30 °C at 4 A on 1 cm² of copper, suitable for HVAC damper actuators and seat-heater pads in automotive cabins.
Recommended
Automotive Lighting Drivers
The BTT60302ERAXUMA1 drives interior and exterior LED lighting modules including dome lights, footwell LEDs, and small signal lamps up to 4 A per channel. The current-sense IS pin enables LED open-load detection and short-to-ground diagnostics required by ISO 26262 functional-safety lighting subsystems. Two channels per IC cut PCB footprint for combined rear-lamp or front-fog-lamp modules, and the 42 V load-dump tolerance withstands jump-start transients common in 24 V truck systems.
Recommended
Industrial 24V Power Distribution
Beyond automotive, the BTT60302ERAXUMA1 fits industrial 24 V power-distribution backplanes where solid-state switching replaces relays for PLC outputs, sensor power, and actuator drivers. The 8 V to 36 V supply range covers both 24 V factory-bus rails and 12 V battery backup systems. Dual independent channels with diagnostic IS output enable per-channel health monitoring over SPI or GPIO to the industrial controller, reducing field service costs in PLC and SCADA installations.
Recommended
Smart Fuse / Electronic Circuit Protection
As an electronic replacement for blade fuses, the BTT60302ERAXUMA1 provides resettable overcurrent protection with MCU-readable fault status - eliminating fuse-replacement downtime in service. The integrated short-to-ground, short-to-battery, and overtemperature protection exceed what a passive fuse offers, and the AEC-Q100 qualification extends service life to automotive-grade MTBF targets. Two protected outputs per IC halve the protection-circuit footprint in zone-architectured automotive ECUs.

Key Differentiators
- Dual-channel integration in one PG-TDSO-14-31 package (vs Two BTS6143D single-channel switches)
- Smart6 technology with enhanced diagnostic IS pin (vs Older PROFET BTS6143D (Smart3))
- Low 32 mΩ Rds(on) per channel (vs BTS70021EPPXUMA1 dual-channel at higher Rds(on))
Design Notes
Estimated: at 4 A continuous load per channel with 32 mΩ on-state resistance, conduction loss per channel is approximately 0.51 W (P = I²R = 16 × 0.032). Both channels together dissipate about 1.02 W. The PG-TDSO-14-31 package requires a minimum 1 cm² of copper on the exposed pad to keep junction-to-ambient thermal resistance around 50 °C/W. Without this copper area, junction temperature can exceed 150 °C under full load in high-ambient under-hood installations.
Place a 100 nF X7R ceramic bypass capacitor as close as possible to the Vbb pins (5 and 6) to suppress supply transients from load-dump and inductive kickback events. Route the IS pin trace away from switching nodes (Vbb, OUT1/2) and add an RC low-pass filter (1 kΩ + 100 nF) at the MCU ADC input to clean up PWM edge ringing. The exposed pad must be soldered to a continuous copper plane with thermal vias to inner layers for optimal heat spreading.
Do not operate the BTT60302ERAXUMA1 below 8 V supply - the internal charge pump cannot fully enhance the N-channel MOSFET, resulting in high Rds(on) and thermal runaway. Do not exceed 42 V load-dump transients for sustained periods. The IS pin is analog and requires the diagnostic pull-up resistor to Vlogic (typically 5 V or 3.3 V MCU rail); do not leave it floating, as this disables open-load detection. When driving inductive loads (solenoids, valves), ensure the device's internal clamp energy rating is not exceeded for your specific load inductance.
Keep OUT1 and OUT2 traces short and wide to minimize parasitic inductance - long output traces cause voltage ringing that can exceed the OUT pin absolute-maximum ratings during PWM switching. Star-ground the GND pin and IS-pin analog ground near the MCU ADC ground reference to avoid digital switching noise coupling into the diagnostic signal. Place the input logic signals (IN1, IN2) on a separate trace layer or far from the OUT traces to prevent crosstalk.
