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.
