LTC4062EDD#PBF

Battery Chargers Overview

The LTC4062EDD#PBF is a standalone linear lithium-ion battery charger IC manufactured by Analog Devices Inc. It operates from an input voltage range of 4.75V to 16V and delivers up to 1.5A of charge current. The device integrates thermal regulation to dynamically reduce current during high-temperature operation, maintaining constant temperature without external components. It supports trickle charging for deeply discharged batteries and includes safety timers to terminate charging if the process exceeds the programmed duration.

Battery Chargers Feature Summary

• Integrates thermal regulation circuitry to automatically reduce charge current based on junction temperature
• Supports programmable charge termination via timer or current threshold detection
• Provides status indication through open-drain flags for charge active and fault conditions

Battery Chargers Applications

• Portable electronic devices requiring single-cell lithium-ion battery management
• Handheld instruments with limited power supply headroom
• Battery-powered equipment needing simplified linear charging solutions

Battery Chargers Procurement Notes

Verify the specific suffix #PBF indicates lead-free RoHS compliance when ordering. Confirm package type DFN-10 matches the target PCB footprint. Check manufacturer documentation for updated lifecycle status as availability may vary by region.

Battery Chargers Selection Notes

Select this component for applications where input voltage exceeds battery voltage but does not require high efficiency switching. Suitable for designs prioritizing low component count over power conversion efficiency. Ensure input source can handle peak charge currents without excessive voltage drop.

Battery Chargers Part Context

This part belongs to the LTC406x family of linear chargers designed for single-cell lithium-ion applications. It shares functional similarities with other members in the series but differs in maximum current ratings and package options. The DFN-10 package provides thermal performance advantages over smaller footprints.

Battery Chargers FAQ

How does the LTC4062 handle overheating during charging?

The device features integrated thermal regulation that reduces the charge current proportionally when the junction temperature approaches a preset limit, preventing thermal shutdown.

What determines the end of the charging cycle?

Charging terminates when the input current drops below approximately one-tenth of the programmed charge current or when the internal safety timer expires, whichever occurs first.
