The Analog Devices LTC6802IG-2#PBF is a lithium-ion battery stack monitor that measures the voltage of 1 to 12 series-connected cells. It reports measurements over a serial interface and includes integrated over-voltage and under-voltage fault detection.
Supporting 1 to 12 cells covers common module sizes for lithium-ion packs. The over/under voltage fault protection is a hardware-level trip that can trigger an interrupt or drive a shutdown FET without waiting for the host microcontroller to poll.
