MIC79110
Simple 1.2A Linear Li-ion Battery Charger General Description
The Micrel MIC79110 is a simple and accurate lithium-ion
battery charger. The part features a built-in pass transistor,
precision programmable current limiting (В±5%), and
precision voltage termination (В±0.75% over temperature).
The MIC79110 packs full functionality into a small space.
Other features of the MIC79110 include two independent
indicators: a digital end-of-charge signal that is
programmable with a resistor-to-ground and an analog
current output that is proportional to the output current,
allowing for monitoring of the actual charging current.
Additional features include very low dropout (550mV over
the temperature range), thermal shutdown, and reverse
polarity protection. In the event the input voltage to the
charger is disconnected, the MIC79110 also provides
minimal reverse-current and reversed-battery protection.
Available in both п¬Ѓxed 4.2V and adjustable outputs, the
MIC79110 is offered in the leadless 10-pin 3mm Г— 3mm
DFN with an operating junction temperature range of
–40˚C to +125˚C.
