LM3658 Dual Source USB/AC Li Chemistry Charger IC for Portable Applications

Check for Samples: LM3658

FEATURES

DESCRIPTION

The LM3658 is a single chip charger IC designed for

handheld applications. It can safely charge and

maintain a single cell Li-Ion/Polymer battery operating

from an AC wall adapter or USB power source. Input

power source selection of USB/AC is automatic. With

both power sources present, the AC power source

has priority. Charge current is programmed through

an external resistor when operating from an AC wall

adapter allowing charge currents from 50 mA to 1000

mA. When the battery is charged using USB power,

charge currents of 100 mA or 500 mA are pin-

selectable. The termination voltage is controlled to

within ±0.35% of 4.2V.

The LM3658 requires few external components and

integrates internal power FETs, reverse current

Continuous Over-current and Temperature

Protection

The LM3658 operates in five modes: pre-qualification

mode, constant-current mode, constant-voltage

mode, top-off mode and maintenance mode.

Additionally, the charger IC operates as a linear

regulator in “LDO mode”, when the AC wall adapter is

connected and no battery is present. Optimal battery

management is obtained through thermal regulation,

battery temperature measurement and multiple safety

timers. The LM3658 provides two open-drain outputs

for LED status indication or connection to GPIOs.
