LTC4412ES6#TR

OR Controllers, Ideal Diodes Overview

The LTC4412ES6#TR is a low-loss PowerPath controller manufactured by Analog Devices Inc., designed to manage power switching between a battery and an auxiliary source like a wall adapter. It controls an external P-channel MOSFET to create a near-ideal diode function, minimizing voltage drop to typically 20mV when conducting. The device operates with a supply voltage range of 2.5V to 28V and features a typical quiescent current of 11µA. Packaged in a surface-mount TSOT-23-6 format, it supports automatic power path management for single-cell lithium-ion batteries.

OR Controllers, Ideal Diodes Procurement Notes

Verify the specific suffix #TR indicates tape-and-reel packaging configuration against official Analog Devices documentation. Confirm that the ES6 designation corresponds to the commercial temperature grade (-40°C to +85°C) and TSOT-23-6 package variant. Ensure compatibility with external P-channel MOSFET selection for the intended load current requirements.

OR Controllers, Ideal Diodes Selection Notes

Select this component for applications requiring minimal power loss during source switching. The wide input voltage range accommodates 1 to 6 series-connected lithium-ion cells. Consider the low static current for battery longevity. Verify that the external MOSFET selected can handle the required load current while maintaining the low on-resistance necessary for the 20mV drop specification.

OR Controllers, Ideal Diodes Part Context

The LTC4412 belongs to Analog Devices' PowerPath family of controllers, offering a robust solution for managing power transitions in portable electronics. Unlike standard diodes, this controller actively drives an external FET to reduce conduction losses significantly. The ES6 variant specifically denotes the commercial grade version housed in the compact TSOT-23-6 package, suitable for space-constrained designs.
