BQ30Z554-R1数据手册TI中文资料规格书

描述 Description

The bq30z554-R1 device is a fully integrated Impedance Track gas gauge andanalog monitoring single-package solution that provides protection andmonitoring with authentication for 2-series, 3-series, and 4-series cell Li-Ionbattery packs. The bq30z554-R1 device incorporates sophisticated algorithms thatoffer cell balancing while charging or at rest.
The device communicates via an SBS v1.1 interface, providing high accuracycell parameter reporting and control of battery pack operation, and can bedesigned into systems that require AC peak power (TURBO mode), using a method toensure that system performance is not disrupted.
An optimum balance of quick response hardware-based protection along withintelligent CPU control delivers an ideal pack solution. The device has flexibleuser-programmable settings of critical system parameters, such as voltage,current, temperature, and cell imbalance, among other conditions.
The bq30z554-R1 device has advanced charge algorithms, including JEITAsupport, enhanced cell charging, and adaptive charging compensating chargelosses, enabling faster charging. In addition, the bq30z554-R1 device canmonitor critical parameters over the life of the battery pack, tracking usageconditions.
A general purpose output is used for power interruption, employing anexternal push button switch.
The advanced snapshot and black box functionality show critical informationfor analysis of returned battery packs.
SHA-1 authentication with secure memory for authentication keys enablesidentification for genuine battery packs beyond doubt.
