Hall input terminals (Pin (8), (9))

Operating DC Level of Hall Inputs (Pin (8), (9))are 2.5~VCC − 0.8 V as specified.

If the voltage appeared at Hall Sensor output terminal within this range, there’s no requirement of external

connecting level shifting resistor.

But Ra, (or Ra and Rb) is required to connect series with Hall sensor if this is not.

Rd : Dynamic Resistance of Hall Sensor.

• We recommend to connect noise suppression use capacitance between IN A and IN B for stable

operation.
