DESCRIPTION
The MP2723 is a 3A, highly integrated, switch-
mode battery charge management device for
single-cell Li-ion or Li-polymer batteries. This
device works with NVDC system power path
management, and is suitable for a variety of
applications including smartphones, tablets,
wireless cameras, and other portable devices. Its
low-impedance power path optimizes efficiency,
reduces battery charging time, and extends
battery life. The I2C serial interface allows the
device to be flexibly controlled due to its charging
and system settings.
The MP2723 supports 5V input sources,
including standard USB host ports, USB
charging ports, and USB-compliant wall
adapters. The device provides USB input type
detection via the DP/DM pins.
It supports USB On-The-Go (OTG) operation by
supplying 5V on the input bus with an output
current limit up to 1.5A.
The MP2723 also initiates and completes a
charging cycle without software control. It
automatically detects battery voltage and
charges the battery in different stages. The
charger automatically terminates when it detects
that the battery is fully charged. If the battery
drops below its recharge threshold, the charger
automatically starts another charging cycle.
Charging Status Indicator
Safety Features Include Configurable JEITA
for Battery Temperature Protection for
Charge Mode, Battery Charging Safety
Timer, Thermal Regulation and Thermal
Shutdown, Watchdog Monitoring I2C
Operation, and Input/System Over-Voltage
Protection
The charger provides various safety features for
battery charging and system operations,
including a charging safety timer, battery
temperature monitoring, and over-voltage and
over-current protections. When any fault occurs,
the charger asserts INT to host. The device
provides BATFET disable control to enter
shipping mode, as well as system reset
functionality via the DISC pin.
APPLICATIONS
Tablet PCs
Smartphones
Wireless Cameras
Other Portable Devices
The MP2723 is available in a QFN-26
(3.5mmx3.5mm) package.
