MP2663
5.2V System, 500mA, I2C-Controlled
Battery Charger with Power Path
Management for Single-Cell Li-ion Battery
DESCRIPTION
The MP2663 is a highly integrated, single-cell
Li-ion/Li-polymer battery charger with system
power path management for space-limited,
portable applications. The MP2663 uses input
power from either an AC adapter or a USB port
to supply the system load and charge the
battery independently. The charger features
pre-charge, constant current (CC) and constant
voltage (CV) regulation, charge termination,
and charge status.
The power path management function ensures
continuous power to the system by
automatically selecting the input, the battery, or
both to power the system. This power stage
features a low dropout regulator from the input
to the system and a 100mΩ switch from the
battery to the system. Power path management
separates the charging current from the system
load, which allows for proper charge termination
and keeps the battery in full-charge mode.
The MP2663 provides system short-circuit
protection (SCP) by limiting the current from the
input to the system and the battery to the
system. This feature is especially critical for
preventing the Li-ion battery from being
damaged by excessively high current. An on-
chip battery under-voltage lockout (UVLO) cuts
off the path between the battery and the system
if the battery voltage drops below the
programmable battery UVLO threshold, which
prevents the Li-ion battery from being over-
discharged. An integrated I2C control interface
allows the MP2663 to program the charging
parameters, such as input current limit, input
voltage regulation limit, charging current,
battery regulation voltage, safety timer, and
battery UVLO.
The MP2663 is available in a 9-pin
1.55mmx1.55mm WLCSP package.
