The Future of Analog IC Technology
DESCRIPTION
The MP2610 is a monolithic switching charger
for 1 or 2 cells Li-Ion battery packs with a built-
in internal power MOSFET. It achieves up to 2A
charge current with current mode control for
fast loop response and easy compensation.
The charge current can be programmed by
sensing the current through an accurate sense
resistor.
MP2610 regulates the charge current and
charger voltage using two control loops to
realize high accuracy CC charge and CV
charge.
Fault condition protection includes cycle - by -
cycle current limiting and thermal shutdown.
Other safety features include battery temperature
monitoring, charge status indication, and
programmable timer to cease the charging cycle.
The MP2610 requires a minimum number of
readily available standard external components.
The MP2610 is available in 4mm×4mm 16-pin
QFN package.

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
J
(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-layer board.
