UNLESS OTHERWISE NOTED, this document contains PRODUCTION DATA.
An open LED in any channel interrupts the current flow of that channel. If the LED current in the sensing circuit falls below the defined threshold thOLED, then the device pulls the DIAGx pin of the affected channel low (for example, for use as an interrupt to a microcontroller). The output-voltage regulation is with respect to the set point of the voltage-control loop (resistor divider network on the OVFBx pin). Removal of the failure releases the DIAGx pin automatically.
