8.1 Overview

The LM66100-Q1 is a Single-Input, Single-Output (SISO) integrated ideal diode that contains a P-channel MOSFET to minimize the voltage drop from input to output. The LM66100-Q1 can operate over an input voltage range of 1.5 V to 5.5 V and support a maximum continuous current of 1.5 A.

The chip enable works by comparing the CE pin voltage to the input voltage. When the CE pin voltage is higher than VIN by 80 mV, the device is disabled and the MOSFET is off. When the CE pin voltage is lower than VIN by 250 mV, the MOSFET is on. The LM66100-Q1 also comes with reverse polarity protection (RPP) that protects against events where the VIN and GND terminals are swapped.
