Fault protection covers over-current, over-temperature, and over-voltage conditions — three common failure modes in charging systems that would otherwise cook the electrolyte or lift the terminals. ## 28-QFN with exposed pad, industrial temp range Housed in a 28-lead WFQFN with exposed pad (4×5 mm body), the part requires a thermal land on the PCB to pull heat from the internal power FETs — the pad must be soldered to a copper plane for the full -40°C to 125°C junction range to hold. The 125°C TJ ceiling covers engine-bay or sealed-enclosure ambient where the self-heating from the charge path adds 30–40°C above the air temperature. ## Active production, ROHS3, sourced per RFQ ROHS3 compliant per the manufacturer's declaration; no halogen or phthalate exemptions claimed.","metaTitle":"LTC4162IUFD-SADM#PBF Lead-Acid Battery Monitor, 3-12 Cells","metaDescription":"Analog Devices LTC4162IUFD-SADM#PBF PowerPath series lead-acid battery monitor, 3-12 cells, I²C interface, 28-QFN.
