Pin Functions
Pin name
Function
VIN
A limiting resistor is connected across VCC and VIN to adjust the current flowing into VIN to be 6mA to 50mA, which generates a voltage
(6.7V) on this pin and supplies a regulated voltage to the IC system and a Hall element.
IN-
IN+
Pins for accepting output from Hall element.
Common-mode input voltage range : 0 to VIN-1.5V
Offset voltage :
±7mV
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.
GND
Ground.
