Battery Chargers datasheet and documents for LTC4120IUD-4.2#TRPBF

LTC4120IUD-4.2#TRPBF

Battery Chargers Overview

The LTC4120IUD-4.2#TRPBF is a single-mode wireless power receiver integrated circuit manufactured by Analog Devices Inc. It operates within an input voltage range of 12.5 V to 40 V and delivers a regulated output voltage between 3.5 V and 11 V with a maximum output current of 400 mA. The device supports lithium-ion and lithium-polymer battery chemistries, featuring a fixed 4.2 V charge voltage configuration for this specific suffix. It functions as both a wireless power receiver and a buck battery charger, housed in a 16-pin QFN package rated for industrial temperatures from -40°C to +85°C.

Battery Chargers Feature Summary

Integrates wireless power reception and buck battery charging in a single component
Supports multiple battery chemistries including Li-Ion and Li-Polymer
Provides regulated output voltage across a wide operating range

Battery Chargers Applications

Wireless power transfer systems requiring integrated charging
Battery-powered devices utilizing Li-Ion or Li-Polymer cells
Evaluation using DC2445A-B demonstration board

Battery Chargers Procurement Notes

Verify the exact part number against official Analog Devices documentation to confirm the 4.2V fixed charge voltage specification associated with the suffix. Ensure compatibility with the required input voltage range and thermal management for the QFN package. Cross-reference datasheets for pinout and electrical characteristics before integration.

Battery Chargers Selection Notes

Select this component when a combined wireless receiver and charger solution is required for Li-Ion or Li-Polymer batteries. The fixed 4.2V output suits standard single-cell lithium applications. Consider the 16-QFN package constraints and the 12.5V to 40V input requirement for system design.

Battery Chargers Part Context

This device belongs to the LTC4120 series of wireless charging ICs. It is functionally related to variants like the LTC4120EUD#PBF but differs in temperature rating and specific charge voltage configuration. The #TRPBF suffix indicates tape and reel packaging with lead-free composition.
