DRV8837

Texas Instruments · Brushed DC motor driver · WSON-8

Drives one small brushed DC motor from a 0 to 11 V supply at up to 1.8 A peak, in a 2x2 mm WSON. Two logic inputs (IN1, IN2) set forward, reverse, brake, and coast, a low RDS(on) of 280 mOhm keeps dissipation down, and nSLEEP powers the bridge down to under 1 uA for battery use. Built-in undervoltage, overcurrent, and overtemperature protection. Sized for toys, cameras, and pumps where the DRV8871's 45 V is more than needed.

Pinout

Pin Name Type Function
1 VM power_in Motor power supply, 0 V to 11 V. Bypass to GND with a 0.1-µF ceramic capacitor rated for VM.
2 OUT1 output H-bridge motor output 1. Connect to one side of the motor winding. Sources/sinks up to 1.8 A.
3 OUT2 output H-bridge motor output 2. Connect to the other side of the motor winding. Sources/sinks up to 1.8 A.
4 GND power_in Device ground. Must be connected to ground; tie to the exposed thermal pad for heat dissipation.
5 IN2 input IN2 logic input for the PWM control interface. Together with IN1 sets the H-bridge state (forward/reverse/brake/coast). Referenced to VCC logic levels (1.8-7 V).
6 IN1 input IN1 logic input for the PWM control interface. Together with IN2 sets the H-bridge state. Referenced to VCC logic levels (1.8-7 V).
7 nSLEEP input Sleep mode input (active-low). Logic low places the device in low-power sleep (120 nA max). Logic high enables normal operation. Internal pulldown.
8 VCC power_in Logic power supply, 1.8 V to 7 V. Bypass to GND with a 0.1-µF ceramic capacitor rated for VCC.
PAD PAD passive Exposed thermal pad on the underside of the WSON package. Must be soldered to the PCB GND plane for proper thermal performance.
