Product overview

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.
  • All features

    • 8-byte unique device ID
    • 32-RAM bytes
    • Battery voltage monitoring
    • Coulomb counter with 12/14-bit AD converter, +/- 80 mV input voltage range
    • Internal temperature sensor
    • I2C interface for gas gauge monitoring and device control
    • One general-purpose I/O
    • Internal or external 32768 Hz time base
