Typical Applications
BTS70041EPZXUMA1 is suitable for 6 applications: Automotive Body Control Module (BCM) Load Driving, HVAC Blower and Valve Control, 12 V Zonal Power Distribution Unit, Industrial PLC Digital Output Module, LED Driver / Daytime Running Light (DRL), Relay Replacement for White Goods and Appliances.
Automotive Body Control Module (BCM) Load Driving
The BTS70041EPZXUMA1 is purpose-built for 12 V automotive body-control applications where it directly drives lamps, door-lock solenoids, and small motors. Its 15 A continuous rating handles headlamp or PTC heater loads, while the 3.1 V to 28 V Vbb range tolerates load-dump transients up to 40 V through external TVS clamping. The DEN-pin diagnostic enables the BCM microcontroller to detect open-load, short-to-ground, and overtemperature faults, supporting ISO 26262 functional-safety requirements. Reverse-battery robustness to -28 V protects the ECU during service miswiring.
Recommended
HVAC Blower and Valve Control
In automotive HVAC systems, the BTS70041EPZXUMA1 drives blower-motor relays and blend-door actuators with up to 15 A continuous current. The exposed thermal pad of the PG-TDSO-14-11 package supports continuous conduction on standard FR-4 2 oz copper, while active current limitation protects the motor windings during stall conditions. The DEN diagnostic reports short-circuit events to the HVAC ECU, allowing rapid fault isolation and avoiding recall risk. AEC-Q100 qualification ensures reliable operation across -40 °C to +125 °C cabin ambient.
Recommended
12 V Zonal Power Distribution Unit
Modern zonal E/E architectures use the BTS70041EPZXUMA1 as a per-channel solid-state fuse-and-switch inside 12 V power distribution units. Its 15 A rating covers most zonal loads (infotainment, lighting, seat controllers), and the DEN pin enables the zonal master to poll channel health at 100 ms intervals. The integrated short-circuit latch clears via a DEN pulse, matching the SPC58 and Aurix zonal-controller diagnostic polling patterns. Lower standby current than electromechanical relays extends vehicle key-off quiescent budget.
Recommended
Industrial PLC Digital Output Module
For 24 V industrial PLC output modules the BTS70041EPZXUMA1 operates at the upper end of its Vbb range with adequate thermal derating. Its high-side topology is preferable to low-side switches when the load is referenced to chassis ground, and the DEN diagnostic supports IEC 61131-3 fault reporting to the PLC backplane. The 175 °C junction temperature rating tolerates the high ambient temperatures found in factory control cabinets. Reverse-battery robustness protects the module during wiring errors during commissioning.
Recommended
LED Driver / Daytime Running Light (DRL)
The BTS70041EPZXUMA1 drives high-current LED strings for automotive daytime running lights and signal lamps up to 15 A total. The DEN pin provides open-load detection that identifies a single failed LED, while short-to-ground protection prevents PCB trace damage if the LED harness is damaged. The exposed thermal pad of the PG-TDSO-14-11 package dissipates the I²R loss at full brightness without an external heatsink. AEC-Q100 qualification supports front-lighting modules mounted in harsh underhood positions.
Recommended
Relay Replacement for White Goods and Appliances
Beyond automotive use, the BTS70041EPZXUMA1 replaces mechanical relays in white-goods appliances such as washing-machine valves, dishwasher heaters, and oven igniters where 15 A switching is required. Its solid-state switching eliminates the audible click of mechanical relays and the contact-wear failure mode, extending product lifetime well beyond electromechanical alternatives. The integrated protection reduces external component count and BOM cost in cost-sensitive consumer applications where the AEC-Q100 grade provides additional thermal margin.

Design Notes
Estimated: at 15 A continuous load current with an assumed R_DS(on) of 8 mΩ at TJ = 25 °C, conduction loss is approximately 1.8 W. Without an explicit heatsink the PG-TDSO-14-11 package relies on the exposed thermal pad soldered to a copper pour. A 1 square inch copper pour on a standard 2 oz FR-4 board gives a junction-to-ambient thermal resistance around 35 °C/W, allowing roughly 4 W of dissipation at 85 °C ambient. For sustained 15 A operation, a 2 to 3 square inch copper area or thermal via array to an inner plane is recommended.
Solder the exposed thermal pad to a top-layer copper pour with thermal vias to inner ground or power planes. Place the input and load decoupling capacitors (typically 100 nF ceramic plus 10 µF electrolytic) as close as possible to the Vbb and OUT pins to minimize parasitic inductance. Keep the IS analog diagnostic trace short and away from switching nodes to avoid coupling into the fault-feedback signal. The IN and DEN traces should be routed away from the OUT load path to prevent dv/dt coupling into the control logic.
Do not exceed the absolute maximum Vbb rating of 28 V continuous or 40 V transient load-dump without external TVS clamping. The reverse-battery robustness rating of -28 V applies only when the device is powered off; active operation under reverse polarity is not supported. The DEN pin must be driven high to enable the IS diagnostic current source — leaving DEN floating will produce indeterminate readings. The short-circuit latch clears only on a falling edge of DEN when IN is low; verify the fault-clearing sequence against the application microcontroller's GPIO behavior at startup.
Use a star-ground topology with the BTS70041EPZXUMA1 ground pin returning directly to the ECU ground plane near the connector. Avoid daisy-chaining the ground pin to other high-current loads. Place a reverse-battery protection diode or P-channel MOSFET upstream of Vbb if the application requires continuous reverse-polarity operation. The IS pin requires a pull-down resistor of typically 1 kΩ to 10 kΩ to ground; the analog current into IS is interpreted by the ADC of the host microcontroller.
