ICL7665SIBAZ-T

Supervisors Overview

The ICL7665SIBAZ-T is a dual-channel voltage supervisor IC manufactured by Renesas Electronics Corporation. It monitors two independent supply voltages and provides active-high reset outputs with open-drain or open-collector configurations. The device operates within an extended temperature range of -40°C to 85°C and is housed in an 8-SOIC package. It supports adjustable or selectable voltage thresholds, allowing for flexible system supervision applications.

Supervisors Feature Summary

• Dual-channel voltage monitoring capability
• Adjustable or selectable threshold voltages
• Active-high reset output configuration

Supervisors Applications

• Multi-rail power supply supervision
• System reset generation in embedded controllers
• Voltage monitoring in industrial instrumentation

Supervisors Procurement Notes

Verify the specific suffix 'BAZ' indicates the tube packaging variant rather than tape-and-reel. Confirm the manufacturer's current production status as some ICL7665 variants have been discontinued. Ensure the selected version matches the required operating temperature range and package dimensions for your PCB layout.

Supervisors Selection Notes

Select this component when dual independent voltage rails require simultaneous supervision. The adjustable threshold feature allows customization for non-standard voltage levels. Compare against single-channel supervisors if only one rail needs monitoring. Verify that the open-drain/reset output logic aligns with the downstream microcontroller input requirements.

Supervisors Part Context

This part belongs to the ICL7665S series of supervisory circuits from Renesas. It is distinct from the ICL7660 charge pump regulators and the discrete JFET transistor also sharing the ICL7665 base number. The 'T' suffix typically denotes tape-and-reel packaging, while 'BAZ' may indicate specific tube packaging or labeling variations.

Supervisors Replacement Considerations

ICL7665SACBAZ is listed as a parameter-equivalent alternative.
