Pin name
FG amplifier output pin.
FG amplifier input pin.
By connecting a capacitor (approx. 0.1µF)
between FG IN + and ground, the logic circuitry is
reset.
Start/stop control pin.
Start (Low) : 0V to 1.5V
Stop (High) : 3.5V to VREG
High when open.
Hysteresis width : approx. 0.5V.
Ground pin (except for output block).
Hall input pins.
High when IN + > IN - , Low when IN + < IN - .
Hall signal should have an amplitude of at least
100mVp-p (differential operation). When Hall
signal noise is a problem, connect a capacitor
between IN + and IN - .
Forward/reverse control pin.
Forward (Low) : 0V to 1.5V
Reverse (High) : 3.5V to VREG
High when open.
Hysteresis width : approx. 0.5V.
