Typical Applications
BTS70041EPPXUMA1 is suitable for 6 applications: Automotive Body Electronics Module, Resistive and Inductive Load Driver (LED, Bulb, Solenoid), Zone ECU Power Distribution, Automotive Heating and HVAC Actuator, Industrial 12 V / 24 V Load Driver, Two-Wheeler and Powersport Electronics.
Automotive Body Electronics Module
The BTS70041EPPXUMA1's 15 A nominal DC current and 4 mOhm typical R_DS(on) at 25 Β°C make it ideal for automotive body-electronics ECUs (door modules, seat controllers, mirror adjusters, tailgate lifters) where one high-side switch drives a multi-load subsystem. Embedded protection - over-current, short-circuit, over-temperature, and reverse battery - replaces discrete fuses and PTCs while the analog IS pin lets the host MCU detect open-load, short-to-ground, and short-to-battery conditions per ISO 16750. AEC-Q100 qualification and 12 V load-dump tolerance per ISO 7637-2 let the part survive jump-start, cranking, and load-dump events common in vehicle electrical systems.
Recommended
Resistive and Inductive Load Driver (LED, Bulb, Solenoid)
The BTS70041EPPXUMA1 drives resistive loads such as LED lighting modules, halogen bulbs, and PTC heaters, and inductive loads such as solenoids, relays, and small DC motors with up to 15 A nominal current. The integrated charge pump keeps the N-channel MOSFET fully enhanced at low PWM duty cycles, enabling LED dimming at 100 Hz to 1 kHz PWM without linearity loss. For inductive loads, the drain-source clamp absorbs demagnetization energy up to E_AS specified in the Infineon datasheet, eliminating external freewheeling diodes in many solenoid and relay applications.
Recommended
Zone ECU Power Distribution
The BTS70041EPPXUMA1 fits modern zone-ECU architectures where a single ECU supplies 12 V to multiple downstream loads via a star of high-side switches. The 4 mOhm typical R_DS(on) keeps conduction loss at 0.9 W at 15 A - manageable in a sealed connector environment without active cooling. The analog IS pin enables per-load current monitoring for load shedding and limp-home strategies defined in AUTOSAR, and the DEN pin toggles between analog sense and digital fault flag so the ECU ADC can be reused for multiple PROFET channels.
Recommended
Automotive Heating and HVAC Actuator
The BTS70041EPPXUMA1 is well suited for HVAC flap actuators, water-valve solenoids, and PTC heater elements that draw up to 15 A from a 12 V battery rail. The device's integrated thermal shutdown and over-current foldback protect the harness during a stalled actuator, while the analog IS pin provides continuous load-current feedback to the HVAC ECU for closed-loop temperature control. AEC-Q100 qualification and the -40 Β°C to +150 Β°C junction temperature range cover under-hood and dashboard-cabin environments typical of HVAC modules.
Recommended
Industrial 12 V / 24 V Load Driver
The BTS70041EPPXUMA1 can also serve industrial 12 V load drivers such as relay coils, solenoid valves, and small brushless DC fans when AEC-Q100 stress-test margins are acceptable for industrial use. The embedded protection and analog current sense simplify IEC 61131-2 / IEC 61000-4-2 / 4-5 compliant PLC output modules. The DEN pin toggling between sense and fault flag helps the PLC diagnostics stack distinguish load failures (open wire, shorted coil) from ECU faults, reducing field-call diagnosis time. Refer to the Infineon datasheet's V_BB maximum before applying to nominal 24 V industrial rails.
Recommended
Two-Wheeler and Powersport Electronics
Motorcycles, e-bikes, ATVs, and small electric powersport vehicles use 12 V rails with high vibration and harsh thermal environments. The BTS70041EPPXUMA1's AEC-Q100 qualification, surface-mount PG-TSDSO-14-22 package with exposed thermal pad, and 15 A current capability suit headlamp, indicator, and accessory relay drivers in these applications. The diagnostic enable pin allows the vehicle ECU to monitor bulb-failure conditions per ECE-R7 and similar regulations, while integrated reverse-battery protection prevents damage from jump-start mistakes common in powersport use.

Key Differentiators
- Mid-range 4 mOhm R_DS(on) sweet spot in PROFET +2 12V family (vs BTS70021EPPXUMA1 and BTS70081EPPXUMA1)
- Drop-in scalability with same footprint across the family (vs Discrete MOSFET + fuse designs)
- Integrated analog current sense eliminates external shunt resistor (vs High-side switch with external current-sense amplifier)
Design Notes
Estimated: at 15 A continuous load and 4 mOhm R_DS(on), conduction loss is P = IΒ² Γ R_DS(on) = 15Β² Γ 0.004 = 0.9 W. The PG-TSDSO-14-22 package with 1 oz copper on a 1 cmΒ² PCB footprint achieves roughly R_thJA β 50 K/W per the Infineon family datasheet, producing a 45 Β°C junction temperature rise above ambient. For PWM-driven loads with high duty cycle, measure the actual R_DS(on) at the operating junction temperature (it roughly doubles at 150 Β°C vs 25 Β°C) and re-check the thermal budget. Keep the exposed thermal pad soldered to a continuous ground copper pour for proper heat spreading.
Place VBB decoupling capacitors as close as possible to pins 6-8 (VBB) and pins 11-13 (GND) of the BTS70041EPPXUMA1 - the Infineon datasheet recommends a 100 nF ceramic in parallel with at least 10 Β΅F electrolytic or ceramic bulk on the battery rail. Keep the IS pin trace short and shielded by a GND keep-out zone to avoid injecting switching noise into the analog current-sense signal; the IS output bandwidth is limited so a simple RC filter at the ADC input is usually sufficient. Route the high-current OUT traces with at least 2 oz copper or copper pours to handle the 15 A nominal current without excessive voltage drop.
Three pitfalls to avoid with the BTS70041EPPXUMA1: (1) Driving inductive loads with stored energy above the datasheet's E_AS limit will trigger avalanche and eventually destroy the part - add a TVS or external freewheel diode for very large solenoids. (2) The DEN pin must be driven high to read analog current on the IS pin; if left floating, the IS output is in fault-flag mode and you will not see real current. (3) The device is rated for 12 V systems only - applying a 24 V truck/lorry rail without external transient protection will exceed V_BB(max). Always refer to the latest revision of the Infineon BTS7004-1EPP datasheet for V_BB(max) and load-dump clamp voltage limits.
Recommended PCB layout from the Infineon application note: place the IC near the load connector to minimize the high-current OUT trace length; use a star-ground topology tying the exposed pad ground, GND pins (11-13), and bulk capacitor ground to a single via farm; keep the IN/DEN traces routed away from the OUT traces to avoid capacitive coupling that can inject logic noise into the gate drive. The IS trace should be a guarded analog track with GND on both sides. Use 4-layer stack-up with a solid ground plane below the IC for best thermal and EMI performance.
