www.DataSheet4U.com TM ® LX2203 Li-Ion Battery Charger P RODUCTION D ATA S HEET DESCRIPTION KEY FEATURES ƒ ƒ ƒ ƒ ƒ ƒ Up to 1A charge current Low drop out design Reverse leakage protection Linear thermal control loop Pre-charge conditioning Programmable Termination Current ƒ Short Circuit protected ƒ Small 3x3mm MLP package APPLICATIONS The LX2203 is a tiny 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. WWW . Microsemi .
