It communicates over a single-wire HDQ interface, keeping the BOM count low in space-constrained portable devices.
Housed in a 10-VFDFN with exposed pad, the supplier device package is a 10-VSON measuring 3x4 mm.
It is designed for single-cell Lithium Ion and Lithium Polymer battery packs. The monitor tracks charge and discharge for a single series cell.
It uses the HDQ (High-Speed Data Queue) single-wire serial interface. This is a proprietary TI protocol that requires only one GPIO on the host microcontroller for data transfer.
