•
Fully Integrated 2-Series, 3-Series, and 4-  
Series Li-Ion or Li-Polymer Cell Battery Pack  
Manager and Protection  
Impedance Track™ gas gauge and analog monitoring  
single-package solution that provides protection and  
monitoring with authentication for 2-series, 3-series,  
and 4-series cell Li-Ion battery packs. The bq30z554-  
R1 device incorporates sophisticated algorithms that  
offer cell balancing while charging or at rest.

•
High Side N-CH Protection FET Drive  
Impedance Track™ Gas Gauging  
Integrated Cell Balancing While Charging or At  
Rest  
The device communicates via an SBS v1.1 interface,  
providing high accuracy cell parameter reporting and  
control of battery pack operation, and can be  
designed into systems that require AC peak power  
(TURBO mode), using a method to ensure that  
system performance is not disrupted.

•
PF Snapshot and Black Box Technology  
Analyze Returned Packs  
AC Peak Power Information Capability  
(TURBO Mode)  
•
•
SBS v1.1 Interface  
Low Power Modes  
An optimum balance of quick response hardware-  
based protection along with intelligent CPU control  
delivers an ideal pack solution. The device has  
flexible user-programmable settings of critical system  
parameters, such as voltage, current, temperature,  
and cell imbalance, among other conditions.
