MP2698
5V, All-in-One Power Bank Solution IC
with 3.6A Boost Current and
5.0A Fast-Charging Capability
DESCRIPTION
The MP2698 is a highly integrated, flexible,
switch-mode, battery charge management and
system power-path management device
designed for single-cell Li-ion and Li-polymer
batteries for use in a wide range of portable
applications.
The IC uses two operating modes, charge
mode and boost mode, to manage system and
battery power based on the state of the input
and output.
When input power is present, the MP2698
operates in charge mode. The device detects
the battery voltage automatically and charges
the battery in four phases: trickle current charge,
pre-charge, constant-current charge, and
constant-voltage charge.
In the absence of an input source, the MP2698
switches to boost mode to power SYS from the
battery. The IC supports BC1.2 output by
identifying the request through DP2/DM2.
To guarantee safe operation, the IC includes
input over-voltage protection (OVP), battery
over-voltage protection (OVP), thermal
shutdown, battery temperature monitoring, and
a programmable timer to prevent the prolonged
charging of an abnormal battery.
With the I2C interface, the IC can flexibly
program the charging and boosting parameters,
such as input current limit, charging current,
battery regulation (charge-full) voltage, safety
timer, boost output current limit, and so on. The
IC can also provide the operation status
through the I2C registers and battery status via
four LEDs.
The MP2698 is available in a QFN-28
(4mmx4mm) package.
