ST1114E/ST1114K/ST1114P SP-ST1114EKP-A.011 Version :A.011 Page :1 ST1114E / ST1114K / ST1114P Double Coil Brushless DC Motor Driver ( 1.8 to 16 Volts ) General Specifications The devices are designed specifically for electronic commutation of double coil DC motor applications. There are intended to be used as an interface between a HALL effect latch and a double coil load. Each device includes a fan tachometer, a lock detection circuit to shut down the drivers for overheat prevention, and two drivers for sinking large load on a single silicon chip. The fan tachometer is designed for fan speed output as open-drain output with a built-in pull-up resistor about 100KΩ and these devices are designed for different applications, ST1114E is for 4 poles fan application, ST1114K is for 8 poles fan application and ST1114P is for rotation detection output. With suitable output pull up resistance, this fan tachometer output can be used directly with bipolar or MOS logic for motor speed monitoring/control. The output driver node “O1” will be “turned to sink” for V(HIN) = logic low. Similarly, the output node “O2” will be “turned to sink” for V(HIN) = logic high. The devices also provide lock and auto-restart function without any timing capacitor. If the motor rotation is stalled by external force or obstacles, overdrive current ( or lock current ) may incur coil overheat/burning. To prevent coil overheat/burning, these devices incorporate lock detection circuit to shut down the drivers. After the motor locking is released, the drivers can be powered up using an automatic self-restart circuit. For 12V application, the drivers are shut down roughly 1 to 3 seconds after the motor is locked. After the drivers are shut down, the automatic self-restart circuit will try to power up the drivers every 1 to 3 seconds. |
