Communication with the host microcontroller runs over an I2C interface, which allows the system to read cell voltages, configure protection thresholds, and retrieve fault status without dedicated SPI lines. ## Fault protection and temperature range On-chip fault protection covers overcurrent, overvoltage, undervoltage, and short-circuit conditions — the four events that most commonly damage a Li-ion pack or trigger a safety shutdown. ## Package and thermal pad layout The tape-and-reel and cut-tape options cover both production reels and prototype quantities; the cut-tape variant is typical for engineering samples or low-volume builds. The device is ROHS3 compliant, which satisfies the EU RoHS exemption regime for lead-free soldering processes without additional exemption paperwork.","metaTitle":"ISL94203IRTZ-T7A Renesas Battery Monitor, 3-8 Cell, 48-TQFN","metaDescription":"ISL94203IRTZ-T7A Renesas multi-chemistry battery monitor, 3-8 cells, I2C, fault protection, -40 to 85°C, 48-TQFN.
