Description
General part information
DRV8704 Series
The DRV8704 is a dual-brushed motor controller for industrial equipment applications. The device controls external N-channel MOSFETs configured as two H-bridges.
Motor current can be accurately controlled using adaptive blanking time and various current decay modes, including an automatic mixed decay mode.
A simple PWM interface allows easy interfacing to controller circuits. A SPI serial interface is used to program the device operation. Output current (torque), gate drive settings, and decay mode are all programmable through a SPI serial interface.
