LTC4065LX-4.1 Datasheet Standalone 250ma Li-ion Battery Charger

Manufacturer: Analog Devices

Overview: LTC4065L/LTC4065LX/ LTC4065L-4.1/LTC4065LX-4.1 Standalone 250mA Li-Ion Battery Charger in 2 × 2.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The LTC®4065L is a complete constant-current/constantvoltage linear charger for single-cell lithium-ion batteries.

Its small size and ability to accurately regulate low charge currents make the LTC4065L especially well-suited for portable applications using low capacity rechargeable lithium-ion cells.

Furthermore, LTC4065L is specifically designed to work within USB power specifications.
