2A Li-Ion Linear Charger and Power Control
TM
DESCRIPTION
The LX2202 Linear Battery Charger is a
multi-state (2 stage) Li-Ion battery charger
(Constant current / Constant voltage) that is
designed to minimize battery charge time
(even from current limited sources such as
USB) and provide a simplified interface to
control battery discharge.
LX2202 features up to 2A charging
current from an AC adapter and an isolated
battery topology to minimize charge time
from current limited sources such as USB.
A thermal control loop maintains a safe
operating temperature at all times.
The
LX2202
provides
a
seamless
complete battery interface. When the input
power source is removed, the LX2202
provides the discharge path for the battery
with extremely low discharge impedance.
This eliminates the need for external
discharge switch and voltage supervisors.
In USB mode, the LX2202 provides
three levels of current limit: 100mA,
500mA, and off.
The LX2202 (compared to the LX2201)
has improved charge and discharge mode
detection circuitry. A UVLO feature prevents
battery charging when VDD is less than 3.6V.
The LX2202 uses three resistors to
program the constant charge current level, for
setting the termination charge current, and for
varying the USB charge current limits.
LX2202 support two types of Li-Ion
battery chemistry; 4.1V and 4.2V through
logical input (VM pin). The LX2202
provides a charging status indicator.
The
LX2202
features
a
pre-charge
conditioning mode for batteries that have
been deeply discharged and also has a top off
charge mode for batteries that are left on the
charger for extended periods.
The LX2202 is available in a high power
4mm x 4mm, 20-pin MLP, surface mount
package.
