Pin No.
Pin name
Function
Equivalent curcuit
16
FGFIL
FG filter pin.
If noise on the FG signal is a problem, insert a capacitor
(under about 2200pF) between this pin and ground.
16
VREG
17
CSD
Restraint protection circuit operating time setting pin/reset
pulse setting pin.
A protection operating time of about 8 seconds can be set by
connecting a capacitor (about 0.068
F) between this pin
and ground. If the protection circuit is not used, connect a
capacitor and resistor (about 4700pF, 220k
) in parallel
between this pin and ground.

VREG
300
18
PH
RF waveform smoothing pin.
If noise on the RF signal is a problem, insert a capacitor
between this pin and ground.
18
VREG
500
19
TOC
Torque specifying input pin.
Normally, this pin is connected to the EO pin.
When the TOC voltage falls, the on duty of the lower side
transistor increases.

20
EO
Error amplifier output pin.

21
EI
Error amplifier input pin.
