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.
