Safe Operating Area (SOA) & Thermal Characteristics
No official SOA curve available for this component. Always operate within absolute maximum ratings specified in the datasheet. Ensure adequate cooling and derate as needed.
Typical Applications
BTS710336ESAXUMA1 is suitable for 6 applications: Automotive Body Control Module (BCM), HVAC Blower and Valve Drivers, Automotive LED Lighting Modules, Industrial PLC Digital Output Module, Relay Replacement in Chassis ECUs, Off-Board Sensor and Actuator Power Distribution.
Automotive Body Control Module (BCM)
The BTS710336ESAXUMA1 directly drives 6 BCM loads such as door lock motors, mirror heaters, and turn-signal bulbs from a single SPI-controlled IC. Its four 1.5 A channels handle low-power loads (LED indicators, small solenoids) while two 3 A channels drive higher-current actuators (mirror fold motors, lamp relays), all with embedded overload and short-to-battery protection. Compared to discrete MOSFET designs, this device reduces PCB area by approximately 60% and centralizes fault diagnostics through one SPI bus, freeing MCU GPIO pins for other body functions.
Recommended
HVAC Blower and Valve Drivers
The BTS710336ESAXUMA1's dual 3 A channels are well-suited for HVAC blower motors and coolant valve actuators that require sustained current up to 3 A with PWM speed control. The 22.5 mOhm on-state resistance keeps conduction losses under 0.2 W per channel at full load, reducing thermal stress on the PCB in the harsh under-dash environment. Embedded thermal shutdown and overcurrent protection ensure the IC survives stalled-motor fault conditions common in HVAC systems.
Recommended
Automotive LED Lighting Modules
Each 1.5 A channel of the BTS710336ESAXUMA1 can drive LED strings for daytime running lights, position lamps, or interior ambient lighting, supporting PWM dimming via the SPI-controlled on/off duty cycle. The 70 mOhm R_DS(on) channels minimize voltage drop and maximize LED brightness consistency across parallel strings, while open-load detection alerts the BCM to burned-out LEDs. With six channels in one package, designers can build a complete front-lighting driver module around a single IC.
Recommended
Industrial PLC Digital Output Module
The BTS710336ESAXUMA1 provides eight-to-twelve-channel digital output density in a single IC for industrial PLC sink/source output modules, replacing banks of relays or optocouplers with MOSFET switches. Its SPI interface enables remote diagnostics over industrial Ethernet gateways, while the -40C to +150C operating range suits factory-floor cabinets and outdoor enclosures. Compared to electromechanical relays, this solid-state design eliminates audible click noise and provides millions of cycles of maintenance-free switching.
Recommended
Relay Replacement in Chassis ECUs
Replacing traditional automotive relays with the BTS710336ESAXUMA1 eliminates audible click, contact bounce, and mechanical wear in chassis ECU applications such as seat control, window lift, and sunroof modules. The 3 A channels handle peak inrush currents of window motors while the embedded diagnostic SPI reports wire-break conditions that a mechanical relay could never detect. Each channel's independent protection prevents a single load fault from disabling the entire ECU.
Recommended
Off-Board Sensor and Actuator Power Distribution
In agricultural machinery and off-road vehicles, the BTS710336ESAXUMA1 powers sensors and actuators distributed across the chassis, providing resettable electronic fuses instead of replaceable blade fuses. Each channel's overcurrent protection triggers at 1.5 A or 3 A according to its rated load, and the SPI interface reports trip events to the main ECU over CAN. The wide operating temperature range ensures reliable cold-start at -40C and sustained operation at +85C ambient under hood.

Key Differentiators
- Highest channel density in SPOC+2 family with mixed current ratings (vs BTS70082EPAXUMA1)
- Latest-generation SMART7 process with smaller die and lower R_DS(on) (vs BTS3050EJXUMA1)
- Dual high-current 3 A channels for motors and lamp loads (vs BTS52004EKAXUMA1)
Design Notes
The PG-TSDSO-24-42 exposed pad must be soldered to a PCB copper pour of at least 200 mm^2 with thermal vias (0.3 mm drill, 1 mm pitch) to keep R_thJA below 35 K/W. At full 6-channel load (estimated 4 x 1.5 A + 2 x 3 A = 12 A total through the die), total dissipation is roughly 4 W, requiring careful thermal management in confined enclosures. Estimated: based on typical SMART7 R_DS(on) values, confirm with datasheet figure 14 thermal curve during final layout review.
Keep Vbb decoupling capacitors (100 nF ceramic + 10 uF electrolytic) within 5 mm of the Vbb pin to suppress inductive load transients. Each OUTx pin should connect directly to the load with the load's return path (chassis or power ground) star-grounded back to the BTS710336ESAXUMA1 Vss/exposed pad. Avoid routing digital SPI traces near the OUTx switching nodes to prevent capacitive crosstalk into SDI/SDO.
The INH (inhibit) pin must be tied high through a 10 kOhm pull-up to enable the device; leaving it floating during MCU reset may place the IC in undefined state. The daisy-chain SDO output drives the next device's SDI in a multi-IC SPI bus - ensure CS propagation timing meets the SPI clock period or the last device in the chain will not latch correctly. Confirm fault-clear timing per the SPI status register read protocol in Infineon's application note AP24004.
PWM dimming of LED channels at frequencies above 200 Hz generates common-mode currents on the load wiring - add a 100 nF Y-cap from each OUTx to chassis ground within 10 mm of the connector to meet CISPR 25 Class 5 emissions. The exposed pad area doubles as an EMI shield when stitch-via'd to the inner ground plane at 5 mm spacing.
