Pin Description
Equivalent circuit
VREG
20
Motor constraint detection output
20
RD This pin output is on when the motor is turning and off
when the constraint protection circuit operates.
Constraint protection circuit operating time setting
21
CSD
Insert a capacitor between this pin and ground.
This pin must be connected to ground if the constraint
protection circuit is not used.
VREG
300 Ω

Start/Stop input
22
S/S A low-level input sets the IC to start mode, and a high-
level input sets it to stop mode.
VREG
3.5 kΩ
22
PWM pulse input
A low-level input specifies the output drive state, and a
23
PWM
IN
high-level or open input specifies the output off state.
When this pin is used for control, the TOC pin voltage
must be set to a control amplifier input that results in a
100% duty.
