DS2784  
1-Cell Stand-Alone Fuel Gauge IC with  
Li+ Protector and SHA-1 Authentication  
www.maxim-ic.com  
GENERAL DESCRIPTION  
FEATURES  
The DS2784 operates from 2.5V to 4.6V for integration  
in battery packs using a single lithium-ion (Li+) or Li+  
polymer cell. Available capacity is reported in mAh and  
as a percentage. Safe operation is ensured with the  
included Li+ protection function and SHA-1-based  
challenge-response authentication.  
ƒ Precision Voltage, Temperature, and Current  
Measurement System  
ƒ Available Capacity Estimated from Coulomb  
Count, Discharge Rate, Temperature, and Cell  
Characteristics  
ƒ Estimates Cell Aging Using Learn Cycles  
ƒ Uses Low-Cost Sense Resistor  
Precision measurements of voltage, temperature, and  
current, along with cell characteristics and application  
parameters are used to estimate capacity. The  
available capacity registers report a conservative  
estimate of the amount of charge that can be removed  
given the current temperature and discharge rate.  
ƒ Allows for Calibration of Gain and  
Temperature Coefficient  
ƒ Li+ Safety Circuitry—Overvoltage,  
Undervoltage, Overcurrent, Short-Circuit  
Protection  
ƒ Programmable Safety Thresholds for  
In addition to the nonvolatile (NV) storage for cell  
compensation and application parameters, 16 bytes of  
EEPROM memory is made available for the exclusive  
use of the host system and/or pack manufacturer. This  
facilitates battery lot and date tracking or NV storage of  
system or battery usage statistics.  
Overvoltage and Overcurrent  
ƒ Authentication Using SHA-1 Algorithm and  
64-Bit Secret  
ƒ 32-Byte Parameter EEPROM  
ƒ 16-Byte User EEPROM  
A 1-Wire® interface provides serial communication at  
16kbps or 143kbps to access data registers, control  
registers, and user memory. Additionally, 1-Wire  
communication enables challenge-response pack  
authentication using SHA-1 as the hash algorithm in a  
hash-based message authentication code (HMAC)  
authentication protocol.  
ƒ Dallas 1-Wire Interface with 64-Bit Unique ID  
ƒ Tiny, Pb-Free, 14-Pin TDFN Package Embeds
