Pin Description
Pin Name
Function
V
IN
A limiting resistor is connected across V
CC
and V
IN
to adjust the current flowing into V
IN
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.

IN
Pins for accepting output from Hall element.
Common-mode input voltage range: 0 to V
IN
-1.5 V
Offset voltage:

OUT1
OUT2
Output transistors of output pins are Darlington-connected. External capacitors or Zener diodes must be
connected to protect output transistors.
RD
Open collector output (Drive mode - ``L'', Stop mode - ``H'')
B1
B2
Base pins for output transistors of Darlington connection.
A capacitor must be connected in an application where radio noise becomes a problem.
C
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.
