TYPICAL APPLICATION CIRCUIT

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 1μF or more.

*3. Power stabilization capacitor on the power side

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