N1
Hall input pin.
IN+ > IN- to “H”, IN+ < IN- to “L”.
Connect the capacitor between IN+ and IN-
when the noise of the hall signal becomes a
problem.
Functions as both the PWM oscillator
frequency setting pin and the initial reset
pulse setting pin. Connect a capacitor
between this pin and ground. It is possible to
set it to about 22kHz with C=2000pF.
Lock (motor constrained) detection state
output. This output is turned on when the
motor is turning and off when the lock
protection function detects that the motor has
been stopped.
Hall signal output pin.
Two kinds of outputs can be selected by
setting the N1 pin.
Sets the operating time for the lock protection
circuit.
Connect a capacitor between this pin and
ground. Connect this pin to ground if the lock
protection function is not used.
PWM pulse signal input. The output goes to
the drive state when this pin is low and to the
off state when this pin is high or open. To use
this pin for control, a CTL amplifier input such
that the TOC pin voltage goes to the 100%
duty state must be provided.
Forward/reverse control input.
Hall signal output (HP output) selection.
