No. 6115-3/4

Sample Application Circuit

5/12V power supply (3.8 to 17V)

Precautions

• Wiring layout for IN– and OUT1 must be designed to prevent interference.

• If the wiring between the Hall element and the IC input is long, noise interference may lead to chattering in the FG

output waveform. In this case, insert a capacitor with 0.01 to 0.001

µF between IN+ and IN–.

• If CT pin is connected to GND, the lockup protection and restart functions are disabled.

• In a circuit configuration as shown above, a current-GND reverse connection will cause a current to flow as follows:

GND -> OUT -> coil -> power supply. The magnitude of this current is limited by the coil resistance. If it is less

than 500 mA, the IC will not be destroyed. If required, insert a diode between VCC and the coil.
