Description
AI
The bq30z554-R1 device is a fully integrated 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.
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.
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.
The bq30z554-R1 device has advanced charge algorithms, including JEITA support, enhanced cell charging, and adaptive charging compensating charge losses, enabling faster charging. In addition, the bq30z554-R1 device can monitor critical parameters over the life of the battery pack, tracking usage conditions.
A general purpose output is used for power interruption, employing an external push button switch.
The advanced snapshot and black box functionality show critical information for analysis of returned battery packs.
SHA-1 authentication with secure memory for authentication keys enables identification for genuine battery packs beyond doubt.
