Sample Application Circuit

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

Precautions

• 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

• 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
