TIMER and PG Operation (Figure 12)
The TIMER pin charges CT as long as limiting action continues, and discharges at a 1/10 charge rate when
limiting stops. If the voltage on CT reaches 4 V before the output is charged, the external FET is turned off and
either a latch-off or restart cycle commences, depending on the part type. The open-drain PG output provides a
deglitched end-of-charge indication which is based on the voltage across the external FET. PG is useful for
preventing a downstream DC-to-DC converter from starting while CO is still charging. PG goes active (open
drain) about 9 ms after CO is charged. This delay allows the external FET to fully turn on and any transients in
the power circuits to end before the converter starts up. The resistor pull-up shown on pin PG in the typical
application diagram only demonstrates operation; the actual connection to the converter depends on the
application. Timing can appear to terminate early in some designs if operation transitions out of the power limit
mode into a gate charge limited mode at low VDS values.
