LTC4068EDD-4.2#PBF Description

Short technical summary and product information.

The LTC4068EDD-4.2#PBF is a complete constant-current/constant-voltage linear charger designed for single-cell lithium-ion batteries. It is manufactured by LT and comes in a low-profile 8-DFN package measuring 3mm x 3mm x 0.75mm.

 

This IC offers a preset charge voltage of 4.2V with ±1% accuracy and a programmable charge current of up to 950mA. It integrates features such as thermal regulation to maximize charge rate without overheating, automatic recharge, and charge status output. The device can charge directly from a USB port and requires minimal external components, making it suitable for portable applications.

 

Key electrical specifications include a battery drain current of less than 2µA when the input supply is removed and an input supply voltage range of 4.5V to 6.5V. The trickle charge threshold is 2.9V for the LTC4068 variant.

 

Applications for this battery charger IC include cellular telephones, PDAs, MP3 players, and Bluetooth devices.
