Description

Motor drive output

4

GND2

Motor drive output system ground

7

VD

Low side output transistor drive current supply

9

VM

Motor drive output power supply and output

current detection.

Connect a resistor (Rf) between this pin and VCC.

The output current is limited to a value determined

by the equation IOUT = VRF/Rf.

Equivalent circuit

8

VCC

Power supply (Systems other than the motor drive

output)

10

VREG

5V regulator output

(control circuit power supply).

Connect a capacitor (about 0.1µF) between this

pin and ground for stabilization.

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.
