Pin Description
11
LVS
Undervoltage protection voltage detection.
Connect this pin to VREG if the VREG level is to be
detected.
If the VCC level is to be detected, insert a zener diode in
series to set the detection level.
VREG
Equivalent Circuit
52kΩ

FGFIL FG filter.
Normally, this IC will be used with this pin open.
Connect a capacitor between this pin and ground
if noise on the FG signal becomes a problem.
