Battery Protection for 3-4 Series Li+ Packs
The MAX1924XEEE+ is a dedicated battery protection IC from Analog Devices, designed for lithium-ion/polymer packs with 3 to 4 series cells. It monitors each cell for over-voltage and under-voltage conditions and triggers a fault output when either threshold is breached.
Parametric Fit for a Multi-Cell BMS
The fault protection covers both over-voltage and under-voltage per cell, which is the minimum necessary for safe Li+ pack operation. The surface-mount assembly is straightforward for reflow processes.
Analog Devices lists the MAX1924XEEE+ as Active with ROHS3 compliance.
