Introduction
The ISL6436 is a fully independent dual channel overcurrent
(OC) fault protection IC for the +2.5V to +5.5V environment.
Each ISL6436 incorporates in a single 8 lead SOIC package
two 80m
N-channel MOSFET power switches for power
control. Independent enabling inputs and fault reporting outputs
compatible with 3V and 5V logic allows for external control and
monitoring. This device features internal current monitoring,
accurate current limiting, integrated power switches and current
limited timed delay to latch-off for system protection. See Figure
1 for typical operational waveforms including both under and
over current situations.
