Supply voltage input terminal. (2.8 V to 5.5 V)
Over voltage detection terminal.
IC switching operation is disabled with detection over voltage.
If the voltage returns to detection level or less, operation is enabled again.
Voltage-input terminal for IC-enable/disable LED-I
A high input on this pin enables the IC to operate while a low input causes it to shut down. The behavior
of the IC is unpredictable if the input on the pin is undefined. Ensure that the pin is tied to either a high or
low level.
