Summary: The BQ3055 device is a fully integrated, single-chip, group-based solution for battery power detection, protection, and certification of 2-cell, 3-cell, and 4-cell tandem Li-ion and Li-Polymer battery packs. Provides a rich array of features. Using its integrated high-performance analog peripherals, the bq3055 device measures and stores the available capacity, voltage, current, temperature, and other key parameters of a Li-Ion or Li-Polymer battery and reports this information via an SMBus v1.1 compliant interface. Give the system host controller. The BQ3055 provides software-based first- and second-level security protection in the event of overvoltage, undervoltage, overtemperature, and overcharging, as well as hardware-based protection for discharge overcurrent, charge and discharge shorts. SHA-1 authentication with secure memory for authentication code storage can unquestionably identify true battery packs. This compact 30-lead TSSOP package maximizes functionality and battery measurement applications while significantly reducing cost and smart battery size. Fully Integrated 2-, 3-, and 4-Series Li-Ion or Li-Polymer Battery Pack Manager and Protection Advanced Compensation Discharge Endpoint Voltage (CEDV) Measure High Side N-Channel (N-CH) Protection Field Effect Transistor (FET) Drive Integrated Battery Equalization Management Low Power Mode Low Power: < 180μA Device Usage Laptop/Notebook PC Medical and Test Equipment Portable Meter The data sheet of BQ3055 can be found in the PDF document (click the PDF file to download) KNM5 Series Moulded Case Circuit Breaker
