# LM66100DCKR (Component)

## Description

1\.5 A Ideal Diode with Integrated P\-Channel MOSFET – Ideal\-diode power management IC designed for reverse\-current blocking, power\-path control, and input polarity protection\. The Texas Instruments LM66100DCKR operates from 1\.5 V to 5\.5 V, supports up to 1\.5 A continuous current, and integrates a P\-channel MOSFET with typical on\-resistance of 79 mΩ at 5 V\. It includes chip enable \(CE\), status indication \(ST\), and reverse\-polarity protection\. The device is housed in a 6\-pin SC\-70 \(DCK\) package and operates from −40°C to \+125°C\.
