Preliminary
LOW-SATURATION,
LOW-VOLTAGE 1.5 CHANNEL
BI-DIRECTIONAL MOTOR
DRIVER
CMOS IC
DESCRIPTION
The device is a 1.5-channel low-saturation bi-directional motor
driver IC. The design is optimal for motor applications, such as
cameras, printers, FDDs, or other portable devices with forward,
reverse, brake and stand-by function.
FEATURES
* Low voltage operation (VDDMIN=VSMIN=1.5V)
* Low saturation voltage (Upper transistor + low transistor residual
voltage; 0.4V typ. at 300mA, VDD=VS=3V)
* Low input current
* Brake function
* High output sinking and driving capability
