CS3720 Datasheet | Cherry Semiconductor Corporation

Description The CS3720 is high current (2A typ) bidirectional DC motor driver. The H-bridge output stage consists of two pairs of power NPN transistors, each with a VSAT=2.3V at IOUT=2A (typ). The three TTL patible inputs, ENABLE1, ENABLE2, and DIRECTION control the output stage. When ENABLE1 is low and ENABLE2 is high, DIRECTION determines which way current flows through the motor coil. Any other bination of ENABLE settings disables the outputs. The CS3720 is protected against overvoltage fault conditions. If a fault condition is detected, the IC shuts down.
