Typical Applications
DRV8432DKDR is suitable for 6 applications: Brushed DC Motor Driver, Bipolar Stepper Motor Driver, Solenoid Driver, Robotics Actuator, Industrial Automation, Automotive Systems.
Brushed DC Motor Driver
The DRV8432DKDR drives brushed DC motors with up to 14 A per bridge, making it ideal for robotics, industrial automation, and automotive actuators. Its low RDS(on) (110 mΞ©) minimizes power loss, and the wide voltage range (0-52.5 V) supports 12 V, 24 V, and 48 V systems. The integrated protection features (OCP, OTP, UVLO) ensure reliable operation in harsh environments. PWM control up to 500 kHz allows precise speed regulation. For a 24 V motor drawing 10 A, the driver dissipates only 11 W (IΒ²R), which is manageable with proper thermal design.
Recommended
Bipolar Stepper Motor Driver
The DRV8432DKDR can be configured as a dual full-bridge driver for a single bipolar stepper motor, providing current regulation for precise positioning. It supports up to 14 A per bridge, enabling high-torque stepper motors in 3D printers, CNC machines, and textile equipment. The PWM current regulation ensures smooth microstepping, and the wide voltage range accommodates various motor ratings. The device's thermal pad must be connected to a heatsink for continuous operation at high currents. With a 48 V stepper motor, the driver can achieve high torque while maintaining efficiency.
Recommended
Solenoid Driver
The DRV8432DKDR can drive solenoids in industrial controls, vending machines, and automotive systems. Its high current capability (up to 14 A) and voltage range (up to 52.5 V) make it suitable for large solenoids. The integrated flyback diodes (via body diodes of MOSFETs) protect the driver from inductive kickback. PWM control allows adjustable holding current, reducing power consumption. The device's protection features prevent damage from overcurrent and overtemperature. For a 24 V solenoid with 5 A holding current, the driver can efficiently regulate the current.
Recommended
Robotics Actuator
In robotics, the DRV8432DKDR drives DC motors and stepper motors for joint actuation and locomotion. Its high current capability supports powerful actuators, and the wide voltage range allows operation from various battery configurations. The device's small footprint (36-HSSOP) saves PCB space, and the integrated protection features enhance system reliability. PWM control enables precise speed and torque control, essential for robotic movements. For a robot arm with a 12 V motor drawing 8 A, the driver can handle the load with adequate cooling.
Recommended
Industrial Automation
The DRV8432DKDR is used in industrial automation for conveyor belts, pumps, and valve control. Its robust protection features (OCP, OTP, UVLO) ensure reliable operation in factory environments. The wide voltage range (0-52.5 V) accommodates various industrial supply rails, and the high current capability drives large motors. The device's efficiency (up to 97%) reduces energy consumption and heat generation. For a 48 V conveyor motor drawing 12 A, the driver can operate continuously with proper heatsinking.
Recommended
Automotive Systems
The DRV8432DKDR is suitable for automotive applications such as power windows, seat adjusters, and cooling fans. Its wide voltage range (up to 52.5 V) handles load dumps and transients, and the protection features prevent damage from short circuits. The device operates over -40Β°C to +85Β°C, meeting automotive temperature requirements. For a 12 V automotive fan motor drawing 10 A, the driver can efficiently control the speed. Note that the DRV8432 is not AEC-Q100 qualified, so for strict automotive compliance, consider the DRV8432DKD or other qualified parts.

Key Differentiators
- Higher output current (14 A per bridge) compared to DRV8412DDW (vs DRV8412DDW)
- Wide load voltage range (0-52.5 V) supports 48V systems (vs DRV8412DDW)
- Integrated protection features (OCP, OTP, UVLO, OVP) enhance reliability (vs DRV8412DDW)
Design Notes
The DRV8432DKDR can dissipate significant power at high currents. For example, at 14 A per bridge with RDS(on) of 110 mΞ©, each bridge dissipates approximately 21.6 W (IΒ²R). The 36-HSSOP package has a thermal pad that must be soldered to a large copper area on the PCB. Use multiple thermal vias to connect the pad to inner and bottom layers for effective heat spreading. For continuous operation above 10 A, consider adding a heatsink or forced airflow.
Place bootstrap capacitors (typically 0.1 Β΅F) as close as possible to the BST and OUT pins to minimize loop inductance. Use low-ESR ceramic capacitors for the logic supply (VDD) and motor supply (VM) decoupling. The high-current paths (VM, OUT1-4, GND) should be wide and short to reduce parasitic inductance and resistance. Separate power ground and logic ground, connecting them at a single point near the thermal pad.
Do not exceed the absolute maximum supply voltage of 70 V on VM. Ensure the logic supply (VDD) is within 10.8-13.2 V; applying higher voltage can damage the device. The sleep pin (SLEEP) must be pulled high for normal operation; leaving it floating may cause unintended shutdown. Also, ensure the OCP, OTP, UVLO, and OVP flag pins are monitored by the microcontroller to handle fault conditions promptly.
