6. IC Shutdown Function
When the DELAY pin is pulled up to 4 V, the IC shutdown function operates. During shutdown, the IC enters the
standby state. To reset the circuit from the shutdown state, the voltage on VCC must be lowered to 4 V or less. After
this reset, when the VCC pin voltage reaches 10.5 V, the IC is restarted.
