Контроллеры и драйверы двигателей / движения / зажигания DRV8704DCPR

Привод двигателя , щеточный DC, 8В до 52В питание, 400мА/2 выхода, HTSSOP-38

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.
