Power Good output

The Power Good output PG indicates an overvoltage or undervoltage condition of the tracker output. For this

beyond the Power Good switching thresholds are indicated by a “low” signal at the Power Good output PG.

The Power Good output PG is an open collector output that requires a pull-up resisitor to a positive voltage

rail. The pull-up voltage must not exceed the absolute maximum ratings of Power Good PG (see “Absolute

maximum ratings” on Page 7).
