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
BTN8982TAAUMA1 is suitable for 6 applications: Automotive Brushed DC Motor Drive (Window Lift, Seat Adjust, Sunroof), E-Bike / E-Scooter Traction Drive, Industrial Pumps and Fans (24 V DC Brushless), Robotic Actuator and Small Servo Drive, DC Solenoid and Valve Driver, Power Tools (Cordless Drill, Saw, Sander).
Automotive Brushed DC Motor Drive (Window Lift, Seat Adjust, Sunroof)
The BTN8982TA's AEC-Q100 qualification and 40 V supply rating make it ideal for 12 V automotive body modules driving brushed DC motors at up to 50 A continuous. Two BTN8982TA devices form a full H-bridge that drives the motor in both directions via PWM on the IN pins. The integrated current limit at 55 A protects the motor and wiring during stall conditions, while the over-temperature shutdown protects the IC during locked-rotor events common in seat-adjust and window-lift mechanisms. The NovalithIC integration eliminates the discrete MOSFET plus gate-driver design, reducing PCB area by roughly 40 percent and improving EMI through shorter switching current paths.
Recommended
E-Bike / E-Scooter Traction Drive
E-bike and e-scooter traction motors up to 1000 W can be driven by two BTN8982TA devices configured as an H-bridge, powered directly from a 24 V or 36 V battery pack within the part's 5.5 V to 40 V range. The 55 A current limit handles peak torque demand on hills, and the integrated charge pump removes the need for a bootstrap capacitor that would complicate the PCB layout. Thermal management is critical - the exposed D2PAK tab must be soldered to a copper pour of at least 2 square inches, and Infineon recommends thermal vias under the tab to inner-layer copper spreads for sustained current above 30 A.
Recommended
Industrial Pumps and Fans (24 V DC Brushless)
Industrial 24 V pumps and fans benefit from the BTN8982TA's wide supply range, three of which can be configured as a three-phase inverter for a BLDC motor. The integrated driver and charge pump replace six discrete MOSFETs plus three gate-driver ICs, drastically simplifying the BOM. Current limiting at 55 A protects windings during mechanical jam events, and the status flag output can be fed back to the controller for predictive maintenance. The exposed tab's thermal performance allows continuous operation at moderate current without a heatsink, provided PCB copper area is generous.
Recommended
Robotic Actuator and Small Servo Drive
Robotic arms, AGV drive wheels, and small CNC actuators use the BTN8982TA in a half-bridge per motor winding, or as an H-bridge for brushed DC gear-motors. The part's 25 kHz PWM capability and adjustable slew rate give designers control over acoustic noise and EMI, important in office and medical robotics. The 50 A continuous rating covers most sub-200 W robotic actuators, and the integrated current sense output enables torque-limiting algorithms in the host microcontroller. Multiple BTN8982TA devices can share the same heatsink plane on a dense motion-control PCB.
Recommended
DC Solenoid and Valve Driver
Industrial solenoid valves, pneumatic actuators, and latching relays can be driven directly by one BTN8982TA per coil, with PWM used to reduce holding current after the initial pull-in. The 5.5 V minimum supply allows direct operation from USB-C or 12 V battery sources, and the 40 V maximum supports 24 V and 30 V industrial rails. Current limiting protects against coil short-circuits, and the integrated thermal shutdown protects against sustained overdrive. The exposed-tab package simplifies mounting on a DIN-rail controller PCB.
Recommended
Power Tools (Cordless Drill, Saw, Sander)
Cordless power tools in the 18 V to 36 V class use one BTN8982TA per brush-commutated motor terminal, paired with a second unit to form a full H-bridge for reversible drill drivers. The 50 A continuous rating handles the stall current of most 18 V brush motors, and the integrated protection eliminates the discrete fuse required in older designs. The AEC-Q100 qualification gives tool manufacturers a path to higher reliability warranties. Reverse-battery protection is straightforward by adding a P-channel MOSFET in the supply path.

Key Differentiators
- Highest current rating in NovalithIC single half-bridge package (vs BTN8962TA)
- Single-device half-bridge reduces BOM vs multi-chip gate driver + FET solutions (vs Discrete MOSFET + gate driver)
- AEC-Q100 qualification for automotive body electronics (vs Non-automotive half-bridge drivers)
Design Notes
The PG-TO263-7-1 package dissipates heat primarily through the exposed tab into PCB copper. For continuous operation at 30 A or above, use a copper pour of at least 1 square inch on the top layer, plus thermal vias to an inner-layer copper spread. Without adequate copper, the junction temperature will exceed 150 C and the thermal shutdown will engage frequently. Estimate: at 30 A continuous with VIN-VOUT = 5 V, dissipation reaches 150 W which is impossible without substantial heatsinking - this part is intended for PWM operation where average dissipation is much lower than peak.
Place the BTN8982TA close to the motor connector to minimize the high-current loop area between the device and the motor. Keep the GND return path wide and short, and use a star-ground topology if multiple power devices share the same PCB. The status flag (STAT) output is open-drain and requires a pull-up resistor; place this resistor near the IC to avoid noise pickup on the line.
Do not exceed the 40 V absolute maximum supply rating - automotive load-dump transients can reach 35 V to 40 V on a 12 V system. Add a TVS diode on the VS pin if the supply is connected directly to the battery. The INH pin is active-high; leaving it floating enables the device, which may cause unexpected motor activation during microcontroller boot. Always pull INH low through a resistor during reset.
