MP2636
3.0A Single Cell Switch Mode Battery Charger
with Power Path Management (PPM)
and 3.0A System Boost Current
DESCRIPTION
The MP2636 is a highly-integrated, flexible
switch-mode battery charger with system power
path management, designed for single-cell Li-
ion or Li-Polymer batteries used in a wide range
of portable applications.
The MP2636 can operate in both charge mode
and boost mode to allow full system
management and battery power management.
When input power is present, the device
operates in charge mode. It automatically
detects the battery voltage and charges the
battery in three phases: trickle current, constant
current and constant voltage. Other features
include charge termination and auto-recharge.
This device also integrates both input current
limit and input voltage regulation in order to
manage input power and meet the priority of the
system power demand.
In the absence of an input source, the MP2636
switches to boost mode through the MODE pin
to power the SYS pins from the battery. The
OLIM pin programs the output current limit in
boost mode. The MP2636 also allows an output
short circuit protection to completely disconnect
the battery from the load in the event of a short
circuit fault. Normal operation will recover as
soon as the short circuit fault is removed. The
MP2636 provides full operating status indication
to distinguish charge mode from boost mode. In
addition, the MP2636 can report the real battery
current in both charge and boost mode via IB
pin.
The MP2636 achieves good EMI/EMC
performance with well controlled switching
edges.
To guarantee safe operation, the MP2636 limits
the die temperature to a preset value of 120^oC.
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.
