ICL7665SCBAZA

Supervisors Overview

The ICL7665SCBAZA is a CMOS micropower over/under voltage detector manufactured by Intersil (Renesas). It features two independently programmable voltage detectors with open-drain outputs. The device operates from a supply voltage range of 1.8V to 16V and consumes typically 3µA. It provides accurate threshold voltages for high or low voltage warnings in systems requiring settable trip points.

Supervisors Feature Summary

• Dual-channel power supply support circuit with individually programmable thresholds
• Micropower operation consuming typically 3µA for extended battery life
• Open-drain output configuration compatible with various logic families
• CMOS technology ensuring low current consumption across wide voltage ranges

Supervisors Applications

• High or low voltage warning systems
• Battery backup switching circuits
• Programmable fault detection in microprocessor systems
• Power supply monitoring in portable electronics

Supervisors Procurement Notes

Verify the specific suffix SCBAZA corresponds to the SOIC-8 surface mount package. Confirm the operating temperature range matches application requirements, as variants exist for commercial and industrial grades. Check for end-of-life status or obsolescence notices from Renesas, as this component may be discontinued. Ensure RoHS compliance details align with regulatory needs for the target market.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required with adjustable thresholds. Consider the 1.8V to 16V input range suitability for the system's power rails. Evaluate the need for open-drain outputs versus push-pull alternatives if interfacing with specific logic levels. Compare against the ICL7665SACBAZ for pin-compatible alternatives if packaging changes are acceptable.

Supervisors Part Context

The ICL7665S series belongs to Intersil's family of super programmable over/under voltage detectors. These devices are designed to replace older discrete solutions by integrating two comparators into a single CMOS chip. The series offers improved accuracy and wider operating ranges compared to standard voltage supervisors, making them suitable for precision power management applications.

Supervisors Replacement Considerations

The ICL7665SACBAZ is listed as a parametric equivalent substitute. Verify pinout compatibility and electrical specifications before substitution. Other members of the ICL7665S family may offer different temperature ranges or package options.
