Описание
Single-channel DC motor driver from Pololu equipped with the DRV8874 system. It is supplied with the voltage from 4.5 V to 37 V. The continuous current per channel is 2.1 A (temporary up to 6 A for 1 second). It allows you to easily control the speed and direction of rotation of the 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 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, the SLEEP pin must be supplied with a voltage in the range from 1.8 V to 5.5 V. DRV8874 offers three possible control modes:
- PHASE / ENABLE (PH / EH)
- PWM (IN / IN)
- Via an independent half-bridge
