The Texas Instruments DRV8432DKDR is a dual full-bridge motor driver in a 36-pin HSSOP package with an exposed thermal pad, supplied on tape and reel. It operates from a 50V nominal supply, rated up to 52.5V maximum, and delivers 7A per channel continuous with a 12A maximum output current rating. The device integrates two full bridges, allowing it to drive two DC motors bidirectionally or one stepper or brushed motor at higher current when the bridges are paralleled. Power dissipation is rated at 5W and the operating temperature range is -40°C to 85°C.

The DRV8432DKDR is used to drive medium-power motors and other inductive loads from a PWM control signal. Typical applications include brushed DC motor drive, bipolar stepper motor drive, and actuator or solenoid control in factory automation, robotics, printers and office equipment, and electric powertrain accessories. The 7A per channel continuous rating with a 12A maximum makes it suitable for mid-size motors that exceed the capability of integrated low-current drivers, while the 50V supply range covers 24V and 48V industrial rails. Note that this record is filed under the Amplifiers - Audio category, but the part is a full-bridge PWM power stage; it belongs to the class-D lineage and can also serve as a high-current PWM amplifier.
