Undervoltage protection voltage detection.
Connect this pin to VREG if the VREG level is to be
detected.
If the V CC level is to be detected, insert a zener diode in
series to set the detection level.
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.
Control loop frequency characteristics correction.
Connect a capacitor between this pin and ground.
Constraint protection circuit operating time setting.
One hall-effect sensor FG output.
(This is an open-collector output.)
