MP2626
USB-Compliant Single Cell Li-ion
Switching Charger with USB-OTG Boost
DESCRIPTION
The MP2626 is a highly-integrated, flexible,
switch-mode battery charger with system power
management, designed for single-cell Li-ion
and Li-Polymer batteries used in a wide range
of portable applications.
The MP2626 can operate in both charge mode
and boost mode to allow full system and battery
power management. It is also able to work as a
boost regulator to power a USB peripheral from
the battery.
The MP2626 automatically detects the battery
voltage and charges the battery in the three
phases: trickle current charge, constant current
charge and constant voltage charge. Other
features include charge termination and auto-
recharge. This IC also integrates both input-
current limit and input-voltage regulation in
order to ensure USB compliant and minimize
the charging time.
The MP2626 can operate as a boost regulator
by setting the MODE pin to a HIGH logic. The
boost regulator includes output current limit and
short circuit protection. As long as MODE pin is
high, the MP2626 will discharge the battery in
the boost mode.
To guarantee safe operation, the MP2626 limits
the die temperature to a preset value of 120oC.
Other safety features include input over-voltage
protection, battery over-voltage protection,
thermal shutdown, battery temperature
monitoring, and a programmable timer to
prevent prolonged charging of a dead battery.
