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
μ
F 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 V
CC
and the coil.
