Power Good output

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

the TLS115D0 compares the output voltage VOUT to the reference voltage VADJ. Variations of the output voltage

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

Transients shorter than the Power Good reaction time tPG,r do not trigger the Power Good output.

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).
