PRODUCTION DATA SHEET
DESCRIPTION
The Microsemi LX2203A is a tiny The LX2203A charges the battery in
linear battery charger for Lithium Ion two phases: constant current and
or Lithium Polymer batteries. The constant voltage. A reduced current
LX2203A includes built in MOSFET, conditioning mode is provided for
accurate current and voltage regulation, deeply discharged batteries. The
reverse blocking protection, over LX2203A automatically restarts if the
temperature control, and charge status battery voltage falls below the top-off
indicator. The accurate programmable threshold. The LX2203A enters a low
charge current and independent quiescent current sleep mode when
termination current programming power is removed.
make it easy to logically reprogram The LX2203A is backward
the charge current limit at any time. compatible with the LX2203. The
difference is the LX2203A can
terminate charging while using CCP
resistors ranging from 90k to 1.5M and
the LX2203 from 90k to 400k.
