Tel886-3-5645656 Fax886-3-5645626 SILICON TOUCH TECHNOLOGY INC. 11-MD123 11-MD123 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; 0.5V 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 SOP14 / DIP-14 package Pin Assignment SOP14 VDD IN1 O1 VS1 O2 IN2 GND 1 2 3 4 5 6 7 14 13 12 GND IN3 O3 VS2 O4 IN4 NC DIP14 VDD IN1 O1 VS1 O2 IN2 GND 1 2 3 4 5 6 7 14 13 12 GND IN3 O3 VS2 O4 IN4 VR 11-MD123 11 10 9 8 11-MD123 11 10 9 8 SP-MD123-A.006 VersionA.006 -1- SILICON TOUCH TECHNOLOGY INC. 11-MD123 PIN NO.

To increase system stability, it is suggestion to connect a resistor RVDD about 100 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.
