Programmable 1-cell Li-ion Fuel Gauge And ProtectorThe 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. By Maxim Integrated Products
