Programmable 1-cell Li-ion Fuel Gauge And Protector

The DS2790 provides a complete fuel gauging and protection solution for single cell Li-Ion battery packs. A low-power 16-bit MAXQ20 Microcontroller with generous program and data memory, combined with an accurate measurement system for battery current, voltage, and temperature provide the ideal platform for customized fuelgauge algorithms. The 2-wire Interface provides an I 2 C*- or SMBus-compatible Communication path between the host and battery pack, while providing password protected programming of the fuel-gauging firmware. EEPROM data memory supports nonvolatile in-pack storage of charge parameters, cell characteristics, usage history, and manufacturing/lot tracking data. An autonomous state machine performs voltage, current, and temperature related protection functions. This capability increases reliability of the whole system by eliminating dependence on the CPU for protection. The DS2790 supports Li-Ion batteries in a wide range of applications.
