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.
