Notice
* Take care not to cause interference due to wiring of IN- and OUT1. * In application of connecting the CT pin to GND, lock protection and restart function are not effective. * 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 magnitude of this current is limited by the coil resistance. If it is less than 500mA, the IC will not be destroyed. If required, insert a diode between VCC and the coil. * The FG pin and RD pin are left open when not used.
