ISL6550CIR

Supervisors Overview

The ISL6550CIR is a precision, flexible supervisor and monitor IC designed for high-end microprocessor and memory power supplies. It features VID-code-controlled reference capabilities and monitors input common mode ranges from 0V to 6V. The device includes overvoltage (OV) and undervoltage (UV) comparators with a propagation delay characteristic. It operates with an open-drain or open-collector output configuration in a single channel. The component utilizes a 20-QFN (5x5) package and integrates monitor circuitry with specific gain-bandwidth product specifications for accurate voltage supervision.

Supervisors Procurement Notes

Verify the exact suffix 'CIR' against the manufacturer's current datasheet to confirm pinout, temperature range, and packaging details. Ensure compatibility with the target system's voltage levels and interface requirements before procurement. Cross-reference the 20-QFN footprint dimensions with PCB design files to prevent assembly errors.

Supervisors Selection Notes

Select this component when precise VID-code controlled voltage monitoring is required for critical logic loads. Consider the 0V to 6V input common mode range and the specific propagation delay characteristics of the OV/UV comparators. Verify that the open-drain output architecture aligns with the downstream controller's input requirements.
