DESCRIPTION
MP2607 is a highly-integrated single-cell Li-
Ion/Li-Polymer battery charger with system
power path management function. It takes input
from either AC adapter or USB port to supply
the system and charge the battery
independently. The charger section features
trickle charge, high-accuracy constant current
(CC) and constant voltage (CV) regulation,
charge termination and charge status.
The system power path management function
ensures continuous supply to the system by
automatically selecting the input, the battery or
both to power the system. This section features
a low drop-out regulator from input to system,
and a 50m switch from battery to system.
Power path management separates charging
current from system load, which allows proper
charge termination and keeps battery stay fully-
charged. It also allows instantaneous power up
of system with a deeply discharged battery.
MP2607 is available in 14pin 3mm*4mm QFN
package.
FEATURES
• Fully Autonomous Charger for Single-Cell
Li-Ion/Polymer Batteries
• Selectable Input Power Sources from AC
Adapter or USB Port
• Built-in Current Limit for USB Port
• Complete Power Path Management for
Simultaneously Powering the System and
Charging the Battery
• 0.75% Charging Voltage Accuracy
• 12V Maximum Voltage for the Input Source
• Programmable Charging Current
• Built-in Timer for Charge Termination
• No External Blocking Diode Required
• Tiny QFN14 (3mm x 4mm) Package
APPLICATIONS
• Smart Handheld Devices
• Cell Phones, PDAs, MP3 Players
• Digital Cameras, GPS
• Handheld Test Equipment

Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature T
J
(MAX), the junction-to-
ambient thermal resistance
JA
, and the ambient temperature
T
A
. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by P
D
(MAX)=(T

(MAX)-
T
A
)/
JA
. Exceeding the maximum allowable power dissipation
will cause excessive die temperature, and the regulator will go
into thermal shutdown. Internal thermal shutdown circuitry
protects the device from permanent damage.
3) The device is not guaranteed to function outside of its
operating conditions.
4) Measured on JESD51-7 4 layers board.
