Notes: *1. Power

−GND wiring

SGND is connected to the control circuit power supply system.

*2. Power stabilization capacitor

For the power stabilization capacitor on the signal side, use the capacitance of 1

μF or more.

*3. Power stabilization capacitor on the power side

For the power stabilization capacitor on the power side, use the capacitance of 1

μF or more.

Connect the power supply on the power side and GND with a thick and shortest pattern.

*4. IN

Hall signal input pin.

Wiring should be short to prevent carrying of noise.

If noise is carried, insert the capacitor between IN+ and IN- pins.

The Hall input circuit functions as a comparator with hysteresis (15mV).

This also has a soft switch section with ±30mV (input signal differential voltage).

It is also recommended that the Hall input level is minimum 100mV (p-p).
