LTC4415EMSE#PBF General Description

The LTC4415 contains two monolithic PowerPath ideal diodes, each capable of supplying up to 4A with typical forward conduction resistance of 50mΩ. The diode voltage drops are regulated to 15mV during forward conduction at low currents, extending the power supply operating range and ensuring no oscillations during supply switchover. Less than 1μA of reverse current flows from OUT to IN making this device well suited for power supply ORing applications.

Key Features

Dual 50mΩ Monolithic Ideal Diodes
1.7V to 5.5V Operating Range
Up to 4A Adjustable Current Limit for Each Diode
Low Reverse Leakage Current (1μA Max)
15mV Forward Drop in Regulation
Smooth Switchover in Diode ORing
Load Current Monitor
Precision Enable Thresholds to Set Switchover
Soft-Start to Limit Inrush Current on Start-Up
Status Pins to Indicate Forward Diode Conduction
Current and Thermal Limit with Warning
Thermally Enhanced 16-Lead MSOP and DFN (3mm × 5mm) Packages

Application

High Current PowerPath^™ Switch
Battery and Wall Adapter Diode ORing
Backup Battery Diode ORing
Logic Controlled High Current Power Switch
Supercapacitor ORing
Multiple Battery Sharing
