RZ7889D

3A Single-CH DC Motor Driver Circuit RZ7889D Description RZ7889D is a monolithic IC designed for driving bi-directional DC motor, It has two pins of logic inputs for controlling the direction, forward and backward. It has a 3A current drive capability, and a low output saturation pressure drop and quiescent current; built-in clamp diode to reverse the impact of the release of inductive load current, Making it in the drive relays, DC motors, stepper motors or control the use of switching power safe and reliable. RZ7889D motor drive for toy vehicles, remote-controlled aircraft motor drive, automatic valve motor, electromagnetic lock drive, precision instruments and other circuits.
