American Technical Support: 800-282-9855 Web Site: www.cherry–semi.com ARCHIVE DEVICE NOT RECOMMENDED FOR NEW DESIGN The CS3720 is high current (2A typ) bidirectional DC motor driver. The H-bridge output stage consists of two pairs of power NPN transis- tors, each with a V SAT=2.3V at IOUT=2A (typ). The three TTL compatible inputs, ENABLE1, ENABLE2, and DIREC- TION control the output stage. When ENABLE1 is low and ENABLE2 is high, DIRECTION determines which way current flows through the motor coil. Any other combination of ENABLE set- tings disables the outputs. The CS3720 is protected against overvoltage fault conditions. If a fault condition is detected, the IC shuts down.
