ST1152B

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 toy, cameras, printers or other portable devices.

Features and Benefits

High current output (max. 1.5A/channel)

Built-in thermal shutdown circuit

Built-in pull down resistor

Low saturation voltage ( Upper transistor + low transistor residual voltage; 0.3V typ. at

400mA, 0.6V typ. at 750mA)

Parallel connection ( two-channel driver: Upper transistor + low transistor residual ; 0.4V

typ. at 800mA )

Separate control logic power supply and motor driver power supply

Brake function

High output sinking and driving capability

Thin, highly reliable package (DIP-14,SOP14)
