The bq20z75 is an SBS-compliant gas gauge and protection-enabled IC that accurately measures the available charge in Li-ion and Li-polymer batteries and provides monitoring and reporting of other critical parameters.
The bq20z75 is a single‑chip solution that measures and records the available charge of Li‑ion or Li‑polymer batteries. It uses Impedance Track™ technology to continuously analyze battery impedance, providing high‑accuracy remaining‑capacity calculations while integrating voltage, current, temperature, short‑circuit and overload protection.
Typical applications include notebook PCs, medical and test equipment, and portable instrumentation. The device is offered in a small 38‑Pin TSSOP (DBT) package and supports flexible configurations of 2 to 4 series cells.
