LX2203 LI-ON BATTERY CHARGER New Product Information and Sales Kit Manufactured by: Microsemi Corporation Integrated Product Group Garden Grove, Telephone: 714 898-8121 More than solutions – enabling possibilities LX2203 Li-On Battery Charger INTRODUCTION WWW . Microsemi .C OM CONFIDENTIAL INFORMATION This new product introduction guide is intended for use only by Microsemi’s sales people and authorized representatives and distributors. This material can be adapted for customer presentations, but the sales strategy and summary [pricing, availability, etc.] is confidential and should not be shown to customers. DESCRIPTION The LX2203 is a tiny 1A linear battery charger for Lithium Ion or Lithium Polymer batteries. The LX2203 includes built in MOSFET, accurate current and voltage regulation, reverse blocking protection, over temperature control, and charge status indicator. The accurate programmable charge current and independent termination current programming make it easy to logically reprogram the charge current limit at any time. The LX2203 charges the battery in two phases: constant current and constant voltage. A reduced current conditioning mode is provided for deeply discharged batteries. The LX2203 automatically restarts if the battery voltage falls below the top-off threshold. The LX2203 enters a low quiescent current sleep mode when power is removed The LX2203 is available in a small 3X3mm, 10 pin- MLP surface mount package.
