Battery monitor IC for multi-cell BMS
The LTC6804IG-2#PBF from Analog Devices is a multi-chemistry battery monitor IC designed for monitoring 1 to 12 series-connected cells in a battery management system (BMS). It communicates over an I²C or SPI interface, making it straightforward to daisy-chain multiple devices for higher cell counts. The part includes over/under voltage fault protection, a critical safety feature for Li-ion and other chemistries. Rated for the industrial temperature range of -40°C to 85°C, it suits indoor and outdoor BMS applications such as energy storage systems, electric vehicles, and backup power.
Package and mounting
Housed in a 48-SSOP package (0.209" body width, 5.30 mm), the LTC6804IG-2#PBF is a surface-mount device. The Tube shipping format is typical for prototype and low-volume builds; production quantities often shift to Tape & Reel. The SSOP footprint is standard and reflow-compatible with lead-free profiles.
Lifecycle status: active, no LTB concern
The LTC6804IG-2#PBF is listed as Active on the manufacturer's lifecycle status. There is no last-time-buy notice or end-of-life announcement.
