It communicates over a UART interface and supports multi-chemistry cell types — Li-ion, LiFePO4, or others — so the same BOM can serve different pack chemistries. If your BMS sees engine-bay heat or cold-soak, this holds the line. The 64-LQFP package (10x10 mm) is a standard, reworkable footprint — a hot-air station on site can swap it without a reflow oven, which matters when a field repair means getting a pack back online without a full board spin. ## Fault protection and monitoring depth Monitors up to 12 cells per IC, with built-in fault protection for overcurrent, overtemperature, and over/undervoltage conditions. That covers the three failure modes that cause thermal runaway or cell damage — the IC itself can trigger a shutdown without waiting for the host MCU. The UART interface is a simple two-wire serial bus, common in battery management systems for daisy-chaining multiple monitor ICs across a high-voltage stack. No complex protocol — just a straightforward read/write transaction for cell voltages and fault flags. ## Compliance and sourcing posture Sourced to order through authorized distribution channels.","metaTitle":"MAX17843ACB/V+ Battery Monitor, 12-Cell, AEC-Q100, Active","metaDescription":"Active-production 12-cell battery monitor IC from Analog Devices.
