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

ST1152B Application Notes
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. The recommended motor driver power dissipation versus temperature is depicted as follows:
