Pin Description
VREG
Equivalent circuit
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.
300 Ω
21
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.

Hall signal output (This is an open-collector output)
25
HP
One of four output types is selected by the N1 and N2 pin
settings.
