DESCRIPTION  
The bq40z50 device, incorporating patented  
Impedance Track™ technology, is a fully integrated,  
single-chip, pack-based solution that provides a rich  
array of features for gas gauging, protection, and  
authentication for 1-series, 2-series, 3-series, and 4-  
series cell Li-Ion and Li-Polymer battery packs.  
High Side N-CH Protection FET Drive  
Integrated Cell Balancing While Charging or At  
Rest  
Full Array of Programmable Protection  
Features  
Using its integrated high-performance analog  
peripherals, the bq40z50 device measures and  
maintains an accurate record of available capacity,  
voltage, current, temperature, and other critical  
parameters in Li-Ion or Li-Polymer batteries, and  
reports this information to the system host controller  
over an SMBus v1.1 compatible interface.
