Low-saturation, Low-voltage

Bi-directional Motor Driver

General Specifications

The device is a two-channel low-saturation bi-directional motor driver IC. The design is

optimal for stepper-motor applications, such as cameras, printers, FDDs, or other portable

devices.

Features and Benefits

z Low voltage operation ( VDD min = VS1 min = VS2 min = 1.5V )

z Low saturation voltage ( Upper transistor + low transistor residual voltage; 0.5V typ. at

400mA)

z Parallel connection ( two-channel driver: Upper transistor + low transistor residual; 0.6V

typ. at 800mA )

z Separate control logic power supply and motor driver power supply

z Brake function

z High output sinking and driving capability

z SOP14 / DIP-14 package
