Motor common terminal input

Overcurrent threshold setup pin. The constant current of the internal constant current source

flows through the resistor connected to this pin. The other side of the resistor is connected to

ground. The voltage across the resistor compares with the voltage converted from the

bottom MOSFET current. If the MOSFET current is high, the part enters the overcurrent

protection mode by turning off the top PWM MOSFET and holding the bottom MOSFET on. I

equal to one electrical cycle (FG). If the FGS pin is connected to VCC, the output has a

period equal to two electrical cycles (1/2FG).

Ground pin

PWM input pin. The PWM input signal is converted to a fixed 156-kHz switching frequency

on the MOSFET driver. The PWM input signal resolution is less than 1%. This pin can also

control the device and put it in or out of standby mode. After the signal at the PWM stays low

(up to 500 µs), the device goes into low-power standby mode. Standby current is

approximately 5 µA. The rising edge of the PWM signal wakes up the device and puts it into

active mode, where it is ready to start to turn the motor.
