The 16-cell count sets the maximum stack voltage the part can measure; for a typical 3.6 V nominal Li-ion cell, the stack reaches about 57.6 V, so the part fits medium-voltage packs in e-bikes, energy storage, or backup battery systems. ## Interface and communication Both I²C and SPI interfaces are available for host-side data readout and configuration — the SPI bus runs faster for bulk register reads during pack balancing or fault logging, while I²C saves pins on a space-constrained BMS controller. The dual-interface option means the same BOM can serve a high-speed production line and a low-pin-count embedded controller without a board spin. ## Package and thermal path Housed in a 64-VFQFN with exposed pad (9×9 mm), the part relies on the pad soldered to a PCB copper plane for heat sinking — the thermal resistance to ambient depends on the board layout, not the package alone. The exposed pad also provides a low-impedance ground return, which matters for the current-sense inputs that share the same reference. Tape & Reel and Cut Tape options cover both high-volume reflow and prototype runs. ## Temperature range and fault protection On-chip over-temperature protection shuts down the monitor if the die exceeds the threshold, preventing runaway in a thermal event. ROHS3 compliance confirms the part is free from the six restricted substances plus the four phthalates, clearing EU regulatory gates without an exemption.","metaTitle":"ISL94216IRZ-T7 Renesas Battery Monitor, 16-Cell, 64-QFN","metaDescription":"ISL94216IRZ-T7 Renesas multi-chemistry battery monitor, 16 cells, I²C/SPI, -40°C to 85°C, 64-QFN.
