DESCRIPTION

The MP2603 is a low cost single cell Li-ion

battery charger IC suitable for low charge

current applications. It features constant current

(CC) and constant voltage (CV) charging

modes with programmable charge current

(50mA–150mA), trickle charge and charge

status indication.

The MP2603 is enabled with an input supply

voltage greater than 3.5V. The charger IC is

disabled when unplugged from the AC adaptor.

To minimize the charger’s total solution cost,

the MP2603 does not need an external reverse

blocking diode, a precision current-sense

resistor or a compensation capacitor at the

output. MP2603 is available in a 5-pin TSOT23

package.
