The ISL94203IRTZ-T7: On-chip fault protection covers over-current, over/under-voltage, and short-circuit conditions — the monitor can flag a pack fault without waiting for a host controller poll cycle.
The 48-WFQFN Exposed Pad footprint is shared across the ISL94203 family, so a single PCB layout can serve multiple BOM variants if the firmware and cell-count configuration differ.
It is a multi-chemistry battery monitor that supervises 3 to 8 series cells, communicates via I²C, and provides fault protection for over-current, over/under-voltage, and short-circuit conditions.
