Description

The STC3100 monitors the critical parameters of

a single-cell Li-Ion battery (voltage, temperature

and current) and includes hardware functions to

implement a gas gauge for battery charge

monitoring, based on a programmable 12- to

14-bit A/D converter. With a typical 30 milliOhms

external sense resistor, the battery current can be

up to 2.5 A and the accumulator system provides

a capacity up to +/-7000 mAh with a resolution of

0.2 mAh.

The device is programmable through the I2C

interface.
