Hall amplifier input.
IN+ > IN– is the input high state, and the reverse is
the input low state.
Connect a capacitor between the sIN+ and IN–
inputs if there is noise in the Hall sensor signals.
Regulated-voltage output pin (5V output)
Connect a capacitor (about 0.1 µF) between this pin
and ground for stabilization.
Power pin (PWM oscillation, PWM comparator,
VCTL amp). Normally connect to VREG.
Voltage detection pin for low-voltage protection.
To detect the supply voltage of 5 V or more, connect
the zenor diode in series to set the detection voltage.
Power pin (V
supply voltage of 12 V or more. 12 V is generated at
the 12 REG pin. To use the 12REG pin, connect this
pin to V
When not used, keep both V
or connect them to GND.
PWM waveform comparator pin.
Normally used in the open condition.
By inputting the voltage directly into this pin, the
output duty can be controlled without using the
VCTL amp.
