Product Overview

The DRV8704DCPR is a 52V dual H-Bridge PWM gate driver in 38 pin HTSSOP package. 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. Internal shutdown functions are provided for overcurrent protection, short-circuit protection, gate driver faults, undervoltage lockout (UVLO) and overtemperature. Fault conditions are indicated by a FAULTn pin and each fault condition is reported by a dedicated bit through SPI.
  • Drives external N-channel MOSFETs, PWM control interface, supports 100% PWM duty cycle
  • Operating supply voltage range from 8V to 52V
  • 50mA to 200mA source current, 100mA to 400mA sink current
  • Integrated PWM current regulation
  • Flexible decay modes such as automatic mixed, slow, fast, mixed decay mode
  • Highly configurable SPI interface
  • Torque DAC to digitally scale current
  • Low current sleep mode of 65µA
  • 5V, 10mA LDO Regulator

Applications

Motor Drive & Control, Industrial, Portable Devices, Building Automation, Consumer Electronics
