Pin Description

Equivalent Circuit

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.

12

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.

14

FC

Control loop frequency characteristics correction.

Connect a capacitor between this pin and ground.

15

CSD

Constraint protection circuit operating time setting.

16

FG

One hall-effect sensor FG output.

(This is an open-collector output.)
