DC Motor 5 Click Board

Product Description

The DC Motor 5 Click Board™ carries the DRV8701 brushed DC motor gate driver from Texas Instruments. The click is designed to run on an external power supply. It communicates with the target MCU over the following pins on the mikroBUS™ line: AN, RST, CS, PWM, and INT.

DRV8701 DRIVER FEATURES

 The DRV8701 is an H-bridge gate driver (also called a pre-driver or controller). The device integrates FET gate drivers in order to control four external NMOS FETs. The device can be powered with a supply voltage between 5.9V and 45V.

Internal protection functions are provided: under-voltage lockout, charge pump faults, overcurrent shutdown, short-circuit protection, pre-driver faults, and overtemperature.

How Does The DC Motor 5 Click Board™ Work?

The motor's velocity and direction can be adjusted with two PWM input signal's.
