Dual DC motor drive module-RZ7899

Overview

product description

This module uses two RZ7899 as driver chips. Each chip can withstand a driving current of 3A and a driving voltage of 3V-25V. It can

Directly use the microcontroller pins to control the output status of OUTA and OUTB.

Both outputs can independently control a DC motor to move forward, backward , and brake; the combination of the two outputs can drive a two-phase four-wire stepper motor.

Applications include: DC motor drive; automatic valve motor drive ; electromagnetic door lock drive; semiconductor refrigeration chip drive, etc.
