DS2792  
Programmable Fuel Gauge  
with UART Interface  
www.maxim-ic.com  
GENERAL DESCRIPTION  
FEATURES  
The DS2792 provides a user-programmable fuel  
gauge solution for Li-Ion and NiMH chemistry 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 fuel-gauge algorithms.  
EEPROM data memory supports nonvolatile (NV)  
in-pack storage of charge parameters, cell  
characteristics, usage history, and manufacturing/lot  
tracking data.  
Accurate Current Measurement for Coulomb  
Counting (Current Accumulation)  
1.5% ±4ꢀV Over ±64mV Input Range  
1.5% ±267ꢀA Over ±4.2A Range Using an
