MP2632
All-in-One, 3A Battery Charger
with 3A Boost Current
DESCRIPTION
The MP2632 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 MP2632 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 MP2632 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 MP2632 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 MP2632 provides an all-in-one
solution for power banks and similar applications
without an external micro-controller.
The MP2632 is available in a 26-pin QFN
(4mmx4mm) package.
