ICL7665SIBA

Supervisors Overview

The ICL7665SIBA is a CMOS micropower supervisory circuit manufactured by Renesas Electronics Corporation. It integrates two individually programmable voltage detectors on a single chip, designed for over/under voltage monitoring. The device operates within an input voltage range of 1.6V to 16V and features adjustable trip points. It consumes typically 3μA during operation, making it suitable for battery-powered applications. The component utilizes an SOIC-8 surface-mount package and provides open-drain outputs without manual reset or watchdog timer functionality.

Supervisors Procurement Notes

Verify the specific suffix 'IBA' against official Renesas documentation to confirm pinout and electrical specifications, as suffixes often denote package type or temperature range variations. Confirm availability status, as some variants in this series may be subject to end-of-life notices. Ensure compatibility with existing PCB footprints and thermal management requirements before integration into production designs.

Supervisors Selection Notes

Select this component when designing systems requiring dual independent voltage monitoring with minimal power draw. The adjustable threshold capability allows customization for specific supply rail requirements. Consider the SOIC-8 package constraints for space-limited designs. Verify that the open-drain output configuration aligns with the downstream logic level requirements of the microcontroller or processor being monitored.

Supervisors Part Context

The ICL7665S belongs to the Intersil/Renesas family of super CMOS micropower supervisory circuits. This series is engineered for high reliability in portable and battery-operated environments. The technology leverages advanced CMOS processes to achieve microampere-level standby currents while maintaining precise voltage detection capabilities across commercial and industrial temperature ranges.

Supervisors Replacement Considerations
