CS3720
2A H-Bridge Driver
Description
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 VSAT=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.
