SC33020H
2A Load Switch with Reverse Current Blocking
Description
The SC33020H is an integrated 2A Load Switch with reverse current blocking.
It operates from an 1.
6V to 5.
5V input supply.
The SC33020H leaves the output node floating when the part is disabled.
The device provides extremely low 32mOhm ON resistfeaantcuere(RpONre) vineanntsuclutrrare-snmt afrlol pmacflkoawgien.

Whenever Vout to VIN voltage exceeds the reverse blocking threshold, reverse blocking is activated regardless of the IC enable state either (ON or OFF).
The SC33020H is offered in a tiny 0.
