Description

Dual DC motor drive module RZ7899

This module can be used to drive common DC motors and stepper motors.

Only need a single-chip computer, coupled with this module, you can drive commonly used small motors.

The procedure is also very simple.

Controlling the change of the high and low levels of the two pins can realize the forward rotation, reverse rotation and braking of the motor.

Power supply voltage: 3V ~ 25V

Maximum drive current: 3A

Control motor forward, reverse and brake

Can use PWM driver

Dual-channel DC motor drive module-RZ7899, this module uses two RZ7899 as drive chips, each chip can withstand 3A drive current and 3V-25V drive voltage, you can directly use the microcontroller pin to control the output state of OUT A and OUT B.

Both outputs can independently control the forward, backward, and braking of a DC motor; the combination of the two channels 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.

Hello my friend. Thanks for sharing this. The datasheet of this chip doesn't say much, so if you could kindly confirm a couple of things it would be very much appreciated. Apparently to control two DC motors I would provide a PWM signal to the Fi pin of each driver, while the direction of the motor would be controlled via Bi pin - logic level 1 would go one direction while logic level 0 would make it turn to the opposite direction. But How the break would work? Thanks for your time.

does it have ttl input on the FI and BI pins?for example if I power it with 24v can I connect FI and BI to 5V arduino?thanks
