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

Low voltage operation ( V_{DD min}= V_{S1 min}= V_{S2 min}= 1.5V )

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

400mA)

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

typ. at 800mA )

Separate control logic power supply and motor driver power supply

Brake function

High output sinking and driving capability

Application Notes

ꢀ

In multiple power supply application, to get suitable input voltage range from external

controller, it is suggestion connecting VDD pin to the same power source with external

controller.

ꢀ

To increase system stability, it is suggestion to connect a resistor R_VDDabout 100Ω between

battery power and driver's VDD pin as shown on application circuit.

The VR pin is a voltage reference output in DIP14 package, let VR pin in floating state in the

application.

The power dissipated by the IC varies widely with the supply voltage, the output current, and

loading. It is important to ensure the application does not exceed the allowable power

dissipation of the IC package.
