MIC79110

Simple 1.2A Linear Li-Ion Battery Charger

General Description

Features

• Input voltage range: 2.5V to 16V

• High output voltage accuracy of ±0.75% over –5°C to

+60˚C and ±1.5% over temperature

• Current Limit ±5% accurate from –5°C ≤ Tj ≤ + 125°C

• Programmable End-of-Charge Flag

The Micrel MIC79110 is a simple and accurate lithium ion

batterycharger. Featuringabuilt-inpasstransistor,precision

programmable current limiting (±5%), and precision voltage

termination (±1.5% over temperature) all in a very small

package, the MIC79110 packs full functionality into a small

space.

Other features of the MIC79110 include two independent

end-of-chargeindications, includingadigitalindicationthatis

programmable with a resistor-to-ground and an analog cur-

rent output that is proportional to the output current, allowing

for monitoring of the actual charging current. Additional

features include very low dropout (500mV over the tempera-

ture range), thermal shutdown, and reverse polarity protec-

tion. In the event the input voltage to the charger is discon-

nected, theMIC79110alsoprovidesminimalreverse-current

and reversed-battery protection.

• Analog output proportional to output current

• Adjustable and Fixed 4.2V Output

• Low dropout voltage of 500mV at 700mA load, over

temperature

• 1.2A output current

• Excellent line and load regulation specifications

• Reverse current and reverse battery protection

• Thermal shutdown and current limit protection

• Tiny 3mm × 3mm MLF™-10 package

• Junction Temperature Range: –40°C to +125°C

Available in both fixed 4.2V and adjustable outputs, the

MIC79110isofferedintheleadless3mmx3mmMLF-10with

an operating junction temperature range of –40˚C to +125˚C.
