點晶科技股份有限公司 SILICON TOUCH TECHNOLOGY INC. ST1116A SP-ST1116A-A.006 Version ：A.006 Page ：1 ST1116A Variable Speed Double Coil Brushless DC Motor Driver General Specifications The device is a driver with variable speed control for two-phase unipolar driver of DC brushless fan motor applications. The device is intended to be used as an interface between a HALL effect latch and a double coil load. The de vice has functions such as driving, rotation detecting, lock protection, self-restart and speed control. An open-drained rotation detect ing output is low while the motor is turning and high impedance when the lock-state is detected. Features and Benefits z Variable fan speed control z Motor starts at low speed z Lock protection and automatic self-restart z Rotation detection output z High output sinking current capability z Connectable direct to a HALL Latch IC z Thin, highly reliable package ( SOP-8 )

This pin co nnected with a pull-up resistor outputs a low level during motor drive and a high level when the motor is stopped. The output voltage of OUT pin depends on the input voltage of VRIN pin. The relationship between the typical output voltage and the voltage of VRIN pin is shown as following table: Output Voltage 0.00 2.00 4.00 6.00 8.00 10.00 12.00 2345678 Voltage of VRIN (Vol.) Voltage of OUT (Vol.) 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:
