bq2054 - Lithium Ion Fast-Charge

General Description

The bq2054 Lithium Ion FastCharge IC is designed to optimize charging of lithium ion (Li-Ion) chemistry batteries.

A flexible pulse-width modulation regulator allows the bq2054 to control voltage and current during charging.

Key Features

  • Safe charge of Lithium Ion battery packs.
  • Voltage-regulated currentlimited charging.
  • Fast charge terminated by selectable minimum current; safety backup termination on maximum time.
  • Charging continuously qualified by temperature and voltage limits.
  • Pulse-width modulation control ideal for high-efficiency switchmode power conversion.
  • Direct LED control outputs display charge status and fault conditions General.
