STC3105

Battery monitor IC with alarm output for gas gauge applications

Features

■ 0.5% accuracy battery voltage monitoring

■ Low battery alarm output with programmable

thresholds

■ Low power: 60 µA in power-saving mode, 2 µA

max in standby mode

■ Ideal for implementation of robust gas gauge

systems using open-circuit voltage and

coulomb counter methods

■ Small 3x2 mm package

Applications

■ Mobile phones, multimedia players, digital

cameras

■ Portable medical equipment

Description

The STC3105 battery monitor includes the

hardware functions required to implement a low-

cost gas gauge for battery monitoring. The

STC3105 uses accurate measurements of the

battery voltage to estimate a battery’s state-of-

charge (SOC). It uses a low cost sense resistor to

precisely sense the charge or discharge states,

detect light-load conditions without ambiguity for

voltage measurements, and accurate SOC

calculation. The coulomb counter method is used

for SOC tracking in high-load conditions.

An alarm output signals a low SOC condition, and

can also indicate low battery voltage. The alarm

threshold levels are programmable.

The device is programmable through an I2C

interface.
