MP2610
2A, 24V Input, 1.1MHz
1/2 - Cell Switching Li-Ion Battery Charger
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.
