LTC4420IMSE#TRPBF

OR Controllers, Ideal Diodes Overview

The LTC4420IMSE#TRPBF is a dual-input monolithic PowerPath prioritizer manufactured by Analog Devices Inc. It operates within an input voltage range of 1.8V to 18V and is housed in a 12-pin MSOP EP package. The device provides backup switchover functionality to maintain critical circuitry during brownout and power loss conditions. It features low operating current and minimizes current draw from inactive supplies, even when their voltage exceeds that of the active supply.

OR Controllers, Ideal Diodes Feature Summary

• Provides backup switchover for critical circuitry during brownout and power loss
• Minimizes current draw from inactive supplies regardless of voltage differential

OR Controllers, Ideal Diodes Applications

• Battery backup systems with interface to low voltage logic
• Prioritization circuits with failsafe backup supply

OR Controllers, Ideal Diodes Procurement Notes

Verify the specific suffix #TRPBF confirms the tape-and-reel packaging format required for automated assembly processes. Ensure the base part number matches the intended voltage range and pin configuration. Cross-reference the manufacturer's latest documentation to confirm RoHS compliance status and any recent product change notifications affecting the component specifications or manufacturing location.

OR Controllers, Ideal Diodes Selection Notes

Select this component when designing systems requiring seamless transition between primary and secondary power sources without significant voltage drop. The low quiescent current makes it suitable for battery-backed applications where standby efficiency is critical. Consider the 12-pin MSOP EP package constraints for thermal management and PCB layout requirements compared to alternative packages like DFN.

OR Controllers, Ideal Diodes Part Context

This part belongs to the LTC4420 series of PowerPath controllers. Variants such as the LTC4420IDD offer similar functionality in different package formats like DFN EP. The IMSE designation specifically indicates the MSOP EP package type. These devices are categorized under Power Supply Controllers and Monitors within the broader portfolio of power management integrated circuits.

OR Controllers, Ideal Diodes Replacement Considerations

LTC4420IMSE#PBF offers identical electrical performance but utilizes tube packaging instead of tape-and-reel.
