Active production — no end-of-life risk for this BOM line
The LTC6804HG-1#PBF: This is a standard catalog part, not a custom or obsolete device, so sourcing is straightforward through distribution channels.
Monitors 1 to 12 series cells — covers most battery stacks
The LTC6804HG-1#PBF is a multi-cell battery monitor IC that measures up to 12 series-connected cells, with a minimum of 1 cell supported. It supports multi-chemistry battery types — Li-ion, LiFePO4, lead-acid, or NiMH — making it suitable for electric vehicle traction packs, stationary energy storage, and backup battery systems. The built-in over/under voltage fault protection reduces the need for external comparators or supervisor ICs, simplifying the BOM and board layout.
SPI and I²C interface — flexible bus integration
The LTC6804HG-1#PBF communicates over either SPI or I²C, selectable by pin strapping, so it can drop into an existing bus without a protocol translator. The -1 suffix indicates the SPI/I²C version with a serial interface that supports a single IC on the bus; the -2 variant uses a different daisy-chain topology for multiple ICs on a single bus.
