Functions
Equivalent circuit
33
V
REG
7-V shunt regulator output
34
CR
PWM oscillator frequency setting
35
CROCK
Reference signal oscillator connection. This oscillator is
used by the motor constraint detection circuit, the clock
disconnection protection circuit, and other circuits.
A protection operation time of about 2.1 seconds can be set
up by connecting a capacitor of about 0.047 μF between
this pin and ground.
36
R
Setting for the charge current used for the VCO circuit C pin
Connect a resistor between this pin and ground. The value
of that resistor must not be lower than 2.7 k
.
37
C
VCO oscillator connection. This pin sets the VCO
frequency.
Connect a capacitor between this pin and ground.
Set the value of the capacitor so that the oscillator
frequency does not exceed 1 MHz.
