Pin Name
Hall input pin.
•High when IN + > IN - .
The input amplitude of over 100mVp-p
(differential) is desirable in the Hall
inputs. Insert a capacitor between the
IN + and IN - pins if the noise on the Hall
signal is a problem.
Control circuit block ground pin.
5V regulator output pin (control circuit
power supply).
Insert a capacitor between this pin and
ground for stabilization.
About 1μF is necessary.
Charge pump capacitor connection pin.
Insert capacitor between CP1 and CP2.
Control power pin.
Insert a capacitor between this pin and
ground to prevent the influence of noise,
etc.
Output power pin.
Insert a capacitor between this pin and
ground to prevent the influence of noise,
etc.
Charge pump output pin.
(Upper-side FET gate power supply)
Insert a capacitor between this pin and
V CC .
Low in reverse relationship.
