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
