BD6385EFV
High Performance, High Reliability 36V Series Stepper Motor Driver

This series is the high-grade type that provides the highest function and highest reliance in the ROHM stepper motor driver series. This series has the perfect various protection circuits and reduces IC's generation of heat by adopting low-ON resistance DMOS and high heat-radiation power package. As for its basic function, it is a low power consumption bipolar PWM constant current-drive driver with power supply's rated voltage of 36V and rated output current of 1.0A to 2.2A. There are input interface types of CLK-IN drive / PARALLEL-IN compatible, CLK-IN drive, PARALLEL-IN drive (3 kinds), so please choose an input mode according to needs of application.
