ST1151A ST1151A Low-saturation, Low-voltage 1.5 Channel Bi-directional Motor Driver General Specifications 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, bake and stand-by function. Features and Benefits Low voltage operation ( VDD Min = 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 Thin, highly reliable package (SOP-8) Pin Assignment VS O1 IN3 GND O2 IN2 VDD IN1 ww w.D ata Sh eet 4U .co m Pin NO. 1 2 3 4 5 6 7 8 Pin Name VS O1 IN3 GND IN1 VDD IN2 O2 Description Power supply pin for output driver Output sinking / driving pin Input pin 3 that determines driving mode Ground pin Input pin 1 that determines driving mode Power supply pin for controller.
