Pins for accepting output from Hall element. Common-mode input voltage range : 0 to VIN-1.5V Offset voltage : ±7mV 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. GND Ground.

If the lock is not released when the C voltage drops to VTH2, the capacitor is charged to VTH1 again. (At this moment, the output is turned ON.) These operations 2), 3) repeated on a cycle of approximately ton : toff = 1 : 6 protect a motor. 4) If the lock is released when the C voltage drops to VTH2, the output is turned ON, starting rotation.
