Frequently Asked Questions
What isolation voltage and data rate does the SI8605AC-B-IS1R achieve on its I2C channels?
The SI8605AC-B-IS1R provides 2.5 kV RMS isolation voltage across 4 open-drain channels supporting up to 10 Mbps, enabling fast and safe I2C communication between high-voltage and low-voltage circuit domains.
Is the SI8605AC-B-IS1R suitable for automotive battery management system designs?
Yes, the SI8605AC-B-IS1R is AEC-Q100 Grade 1 automotive qualified and operates from -40°C to +125°C, making it a strong fit for battery management, on-board charger control, and EV inverter designs requiring isolated 4-channel I2C communication at 10 Mbps.
How does the 16-pin SOIC package of the SI8605AC-B-IS1R compare to smaller isolation alternatives for tight PCB layouts?
The 16-pin SOIC package of the SI8605AC-B-IS1R measures approximately 9.9 mm x 3.9 mm, providing adequate clearance for the 2.5 kV isolation barrier while remaining compatible with standard SMT reflow. Designers needing tighter footprints may consider SSOP variants, but SOIC simplifies rework in automotive prototyping.
