Precautions
• If CT pin is connected to GND, the lockup protection and restart functions are disabled.
• In a circuit configuration as shown above, a power supply/GND reverse connection will cause a current to flow as
follows: GND -> OUT -> coil -> power supply. The value 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.
