MAS6260

Li-ion and LiPo battery charger with LDO

• Both lithium ion and lithium polymer

battery charging

• Low-dropout voltage regulator

DESCRIPTION

MAS6260 is a linear single cell charger IC for both Li-

ion and LiPo batteries. It has integrated low-dropout

regulator

(LDO)

and

several

battery

protection

functions.

MAS6260 uses a CC/CV algorithm to charge the

battery. The fast-charge current can be programmed

using an external resistor. Pre-charge current and

termination current are scaled accordingly. The floating

voltage value options available are 4.2 V, 4.35V and

4.4V.

The input supply voltage is normally used to charge the

battery and provide power to the LDO regulator and

SYS output. When a valid input voltage is not present

and the battery is not empty, the device automatically

switches to battery power.

MAS6260 integrates overcharge, overdischarge and

overcurrent protection circuitry to prevent the battery

from being damaged under fault conditions. It also

features a charger enable input to stop the charging

process when battery overtemperature is detected by

external circuitry.

When the shutdown mode is activated, the battery

power consumption is reduced to typ 1

A to maximize

battery life during shelf time or shipping. The device is

available in a DFN-12 3x3x0.75mm package.
