Function
A limiting resistor is connected across VCC and VIN to adjust the current flowing into VIN to be 6 mA to 50 mA,
which generates a voltage (6.7 V) on this pin and supplies a regulated voltage to the IC system and a Hall
element.
Pins for accepting output from Hall element.
Common-mode input voltage range: 0 to VIN-1.5 V
Offset voltage: ± 7 mV
Output transistors of output pins are Darlington-connected. External capacitors or Zener diodes must be
connected to protect output transistors.
Open collector output (Drive mode - ‘‘L’’, Stop mode - ‘‘H’’)
Base pins for output transistors of Darlington connection.
A capacitor must be connected in an application where radio noise becomes a problem.
Capacitor pin for automatic return function
When the rotation is stopped by an overload, the voltage on this pin is increased, turning OFF the output.
Automatic return from output ‘‘stop’’ to ‘‘drive’’ occurs by making the load proper. The lock detect time can be set
by changing the capacitor constant.
