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
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.
