Single-channel DC motor controller manufactured by Pololu. Equipped with the DRV8876 system, it is supplied with the voltage from 4.5 V to 37 V. The continuous current per channel is 1.3 A (temporary up to 3.5 A for 1 second). The module allows you to control the speed and direction of rotation of one motor, using only two pins of the microcontroller. The controller is also equipped with protection against reverse polarity, too low voltage, too high current and too high temperature. The set includes goldpin connectors, intended for self-soldering.

Connecting the DRV8876 driver

The motor supply voltage in the range from 4.5 V to 37 V should be connected to the VIN or VM pin. In a typical application, it is enough to connect two control lines: the selection of the PHASE rotation direction and the PWM speed regulation to the ENABLE pin. By default, the controller is in sleep mode - to exit it, you need to supply the SLEEP pin with a voltage in the range from 1.8 V to 5.5 V. DRV8876 offers three possible control modes:

  • PHASE / ENABLE (PH / EH)
  • PWM (IN / IN)
  • Via an independent half-bridge

Pins of the DRV8876 driver
Pin Default state Description
VIN Input voltage from 4.5 V to 37 V.
GND The mass of the system for the engine and logic.
VM Pin that gives access to the motor's power supply after activation of the MOSFET protection against reverse voltage. It can be used to power other system components with reverse polarity protection.
OUT1 Engine output 1.
OUT2 Motor output 2.
EN / IN1 LOW Pin 1 for motor turn ON / OFF PHASE / ENABLE (PH / EH).
PH / IN2 LOW Pin 2 to control the direction of rotation of the motor PHASE / ENABLE (PH / EH).
FAULT FLOATING Open-drain, fault output activated with low state. The pin goes low after exceeding the permissible current or voltage. It needs to be pulled up with a resistor to be high by default.
SLEEP LOW The SLEEP input causes the controller to enter the low power state after entering the low state. This pin can also be switched to clear a stuck over current or over temperature fault.
VREF Current limiting threshold reference voltage.
