PRODUCTION DATA SHEET
DESCRIPTION
The LX2203 is a tiny linear battery The LX2203 charges the battery in
charger for Lithium Ion or Lithium two phases: constant current and
Polymer batteries. The LX2203 constant voltage. A reduced current
includes built in MOSFET, accurate conditioning mode is provided for
current and voltage regulation, reverse deeply discharged batteries. The
blocking protection, over temperature LX2203 automatically restarts if the
control, and charge status indicator. battery voltage falls below the top-off
The accurate programmable charge threshold. The LX2203 enters a low
current and independent termination quiescent current sleep mode when
current programming make it easy to power is removed.
logically reprogram the charge current
limit at any time.
