Features: MP2690 All-in-One, 2.5A Battery Charger with 2.1A Boost Current DESCRIPTION Th e MP2690 is a highly integrated, flexib le, switch-mode battery charger with sy stem powerpath management and is design ed for single-cell Li-ion or Li-polymer battery use in a wide range of applica tions. The IC can operate in both charg e mode and boost mode to allow for full system and battery power management. T he IC has an integrated IN-to-SYS pass- through path to pass the input voltage to the system. The pass-through path ha s built-in over-voltage and over-curren t protection and has a higher priority over the charging path. When the input power is present, the device operates i n charge mode. The MP2690 detects the b attery voltage automatically and charge s the battery in three phases: trickle current, constant current, and constant voltage. Other features include charge termination and auto-recharge. The MP2 690 also integrates both input current limit and input voltage regulation to manage input power and me.

MP2690
All-in-One, 2.5A Battery Charger
with 2.1A Boost Current
DESCRIPTION
The MP2690 is a highly integrated, flexible,
switch-mode battery charger with system power-
path management and is designed for single-cell
Li-ion or Li-polymer battery use in a wide range
of applications.
The IC can operate in both charge mode and
boost mode to allow for full system and battery
power management.
The IC has an integrated IN-to-SYS pass-through
path to pass the input voltage to the system. The
pass-through path has built-in over-voltage and
over-current protection and has a higher priority
over the charging path.
When the input power is present, the device
operates in charge mode. The MP2690 detects
the battery voltage automatically and charges the
battery in three phases: trickle current, constant
current, and constant voltage. Other features
include charge termination and auto-recharge.
The MP2690 also integrates both input current
limit and input voltage regulation to manage input
power and meet the priority of the system power
demand.
In the absence of an input source, the IC
switches to boost mode through PB to power
SYS from the battery. In boost mode, OLIM
programs the output current limit, and the IC
turns off at light load automatically. The IC also
uses output short-circuit protection to disconnect
the battery from the load completely in the event
of a short-circuit fault. The MP2690 resumes
normal operation once the short-circuit fault is
removed.
The 4-LED driver is integrated for voltage-based
fuel gauge indication. Together with torch-light
control, the MP2690 provides an all-in-one
solution for power banks and similar applications
without an external micro-controller.
The MP2690 is available in a 26-pin QFN
(4mmx4mm) package.
