Typical Applications
BTN9960LVAUMA1 is suitable for 6 applications: Automotive Window Lift Drive, Automotive Seat Adjustment Motor, Cooling Fan Driver, Electric Water/Oil Pump Driver, Industrial Relay Replacement / Solenoid Driver, E-Bike / Small E-Mobility Motor Controller.
Automotive Window Lift Drive
The BTN9960LVAUMA1's 9.7 mOhm path resistance and 35 A overcurrent detection make it ideal for 12 V window lift motor drivers, where stall currents can spike to 25-30 A when the glass encounters the seal. Two half-bridges form an H-bridge for bidirectional control with PWM speed regulation. The integrated shoot-through protection and dead-time control eliminate cross-conduction that would otherwise stress the MOSFETs, while AEC-Q100 Grade 1 qualification ensures operation across -40C to +150C under-hood environments. The P-channel high-side switch removes the need for a charge pump, reducing EMI emissions that could interfere with adjacent radio modules. The exposed thermal pad of the PG-HSOF-7-1 package provides sufficient heat dissipation for repeated stall events during anti-pinch testing.

Automotive Seat Adjustment Motor
Seat adjustment requires bidirectional brushed DC motor control with smooth PWM speed regulation and reliable stall detection for end-of-travel limits. The BTN9960LVAUMA1's 3.3 uA standby current meets strict key-off parasitic drain budgets, while its 35 A overcurrent threshold safely handles motor stall currents of 20-25 A typical for seat motors. The integrated over-temperature protection shuts the device down before thermal damage occurs during repeated cycling, and the AEC-Q100/Q006 qualification supports the long-term reliability requirements of seat modules. Pairing two BTN9960LVAUMA1 devices in H-bridge configuration provides full four-quadrant control for fore/aft and recline actuators, with the enable pin allowing CAN-controlled power-down when the seat is stationary.
Recommended
Cooling Fan Driver
The BTN9960LVAUMA1 is well suited for automotive and industrial cooling fan motor drives where PWM speed control and quiet operation are required. The P-channel high-side topology eliminates charge-pump-induced audible noise, while the 9.7 mOhm Rdson minimizes conduction losses that would otherwise heat the package and reduce fan lifespan. Operating from 8-18 V, the device accepts direct connection to 12 V automotive rails including cold-crank transients down to 6 V when paired with external hold-up capacitance. Two BTN9960LVAUMA1 units can drive a single-phase BLDC fan, while three units form a 3-phase BLDC driver for higher-power server or HVAC fans. The 3.6 us propagation delay supports PWM frequencies up to 25 kHz, above the audible range for noise-sensitive applications.
Recommended
Electric Water/Oil Pump Driver
For electric water pumps and oil pumps in 48 V mild-hybrid and 12 V conventional automotive systems, the BTN9960LVAUMA1 delivers robust brushed DC motor control with the protection features essential for unattended pumps operating under harsh thermal and vibration conditions. The integrated over-temperature and over-current protections shut the pump down before catastrophic failure, while the under-voltage lockout prevents MOSFET damage during cold-crank events. The 9.7 mOhm path resistance keeps conduction losses below 2 W at 20 A continuous, eliminating the need for an external heatsink in most pump housing designs. The PG-HSOF-7-1 package's exposed pad provides direct thermal coupling to the metal pump housing for additional heat spreading.
Recommended
Industrial Relay Replacement / Solenoid Driver
The BTN9960LVAUMA1 can directly replace electromechanical relays in industrial control systems, providing silent, bounce-free switching with PWM duty-cycle control of solenoid force or heater power. With 35 A peak current capability, the device drives pneumatic solenoid valves, hydraulic actuators, and resistive heating elements. The integrated dead-time control and shoot-through protection are critical when switching inductive loads, eliminating the need for external snubber circuits in many cases. The 250 ns turn-off time supports high-frequency PWM for proportional solenoid control, while the 3.3 uA standby current suits battery-backed industrial control panels. AEC-Q100 qualification provides extra reliability margin for factory floor vibration and temperature cycling.
Recommended
E-Bike / Small E-Mobility Motor Controller
For 24 V and 36 V e-bike controllers using 3-phase brushless DC motors, three BTN9960LVAUMA1 devices form the complete inverter stage with motor-current handling up to 35 A peak. The P-channel high-side switch is especially valuable in space-constrained e-bike controllers where PCB area and EMI compliance are critical - eliminating the charge pump reduces both board size and radiated emissions. The 9.7 mOhm Rdson keeps efficiency above 95% at typical 15 A continuous phase current, extending battery range. The exposed thermal pad couples heat directly to the aluminum controller housing, eliminating external heatsinks. However, designers must verify that 48 V battery transients stay within the 40 V maximum supply rating with adequate TVS clamping.

Key Differentiators
- P-channel high-side switch eliminates charge pump (vs BTS7960B (legacy N-channel high-side NovalithIC))
- Lowest Rdson in 12 V MOTIX family (vs BTN7971B (25 mOhm NovalithIC))
- Integrated 35 A overcurrent detection (vs Discrete half-bridge with external current-sense resistor)
Design Notes
The BTN9960LVAUMA1's PG-HSOF-7-1 package dissipates heat primarily through the exposed thermal pad on the underside. For continuous 20 A load at 9.7 mOhm, conduction loss is approximately 3.9 W. Estimated: with a properly soldered thermal pad connected to at least 1 square inch (645 mm2) of 2 oz copper on a 4-layer FR4 PCB, junction-to-ambient thermal resistance (theta_JA) drops below 30 C/W, keeping junction rise below 120C at 85C ambient. For higher currents, use a dedicated copper pour or aluminum substrate to keep Tj below 150C.
Place the VS supply decoupling capacitor (10 uF X7R ceramic minimum, plus 100 nF high-frequency bypass) within 5 mm of the VS pin. The exposed thermal pad must be soldered to a continuous ground plane with thermal vias (at least 9 vias of 0.3 mm diameter) directly under the pad. Keep high-current OUT traces short and wide (at least 50 mil / 1.27 mm) to minimize parasitic inductance that could cause ringing during switching. Route the IN and EN logic signals away from the OUT switching node to avoid coupling.
Do not exceed 40 V on the VS pin, including load-dump transients in 12 V automotive systems - add a TVS diode (e.g., 33 V SMBJ series) from VS to GND if load-dump protection is not provided upstream. The enable pin must be controlled cleanly; leaving it floating can cause undefined operation. In H-bridge configurations, ensure that the dead-time setting matches the propagation delay to prevent shoot-through. Do not operate without a heatsink path - the device will trigger OTP at sustained junction temperatures above 150C.
When building an H-bridge from two BTN9960LVAUMA1 devices, mirror the layout across the motor terminal to balance parasitic inductance between the high-side and low-side current paths. Keep the gate drive return paths (GND pins) close to the OUT switching nodes. Use a star-ground topology with the motor current return connected directly to the device GND pins, separate from the logic ground of the microcontroller. This prevents motor switching currents from injecting noise into the analog sense circuits.
