Wuxi Microelectronics RZ7899
RZ7899 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.DESCRIPTION
