Stmicroelectronics (STC3100IST) Battery Li-Ion Supervisor & Monitor IC

Battery Li-Ion Supervisor & Monitor IC, I2C Interface, 1 Cell, 2.7 V to 5.5 V supply, MSOP-8 Product Overview The STC3100IST is a battery monitor IC with coulomb counter/gas gauge in 8 pin MSOP package. The device 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 14bit A/D converter. With a typical 30mohm external sense resistor, the battery current can be up to 2.5A and the accumulator system provides a capacity up to +/-7000mAh with a resolution of 0.2mAh. The device is programmable through the I2C interface. Typical applications include cellular phones, PDA, MP3 players, cordless phones, digital cameras, USB appliances and Bluetooth devices.
