ST1155A ST1155A 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 ( VDD min = VS1 min = VS2 min = 1.5V ) 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 High output sinking and driving capability Thin, highly reliable package (SOP-14) taS hee t4U .co Pin Assignment VDD ENA1 O1 VS1 O2 IN1 GND 1 2 3 4 5 6 7 14 13 12 GND ENA2 O3 VS2 O4 IN2 NC m ST1155A 11 10 9 8 w.D a ST1155A_A05.doc Version: A.05 -1- ww www.DataSheet4U.com SILICON TOUCH TECHNOLOGY INC.
