GENERAL DESCRIPTION
The ADM869L is a logic controlled P-channel switch with low
on resistance, capable of sourcing up to 2 A from supply voltages
between 2.7 V and 5.5 V. A user-settable current limit allows
the trip current to be set between 400 mA and 2 A with an
accuracy of ± 21%. This allows the system power supply to be
protected against short circuits and surge currents in peripheral
loads powered via the ADM869L. Over-current and over-
temperature conditions are signalled by a FAULT output.
The ADM869L also offers low quiescent current of typically
12 µA and shutdown current of typically 10 nA.
