ICL7665CSA

Supervisors Overview

The ICL7665CSA is a dual-channel voltage supervisor integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors two independent input voltages to detect overvoltage and undervoltage conditions, providing reliable system protection. The device features adjustable trip points for flexible configuration across various power rails. It operates within an input voltage range of 1.6 V to 16 V and maintains accuracy within 2%. Designed for surface-mount installation in SOIC-8 packages, it supports active high, active low, or open-drain outputs. The component functions efficiently with a supply current of 15 µA and includes battery backup switching capabilities.

Supervisors Feature Summary

• Dual-channel monitoring for simultaneous detection of overvoltage and undervoltage events on separate inputs
• Adjustable threshold voltages allowing customization of trip points for specific application requirements
• Flexible output configurations supporting active high, active low, and open-drain signal types
• Battery backup switching functionality to maintain monitoring continuity during primary power transitions

Supervisors Applications

• Portable instrumentation systems requiring precise power rail supervision
• Memory power backup circuits ensuring data integrity during power loss
• Battery-operated devices needing efficient low-power voltage monitoring

Supervisors Procurement Notes

Verify the exact suffix designation when ordering, as variations such as CSA versus CSA+ may indicate differences in lead-free compliance or manufacturing revisions. Confirm package availability since distribution channels may list restricted stock status. Ensure compatibility with existing board layouts regarding the SOIC-8 footprint. Cross-reference datasheet specifications against current design requirements to validate performance parameters before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required within a compact surface-mount package. Consider its adjustable threshold capability if fixed reference supervisors do not meet specific voltage levels. Evaluate the 15 µA operating current for suitability in battery-powered designs where energy efficiency is critical. Verify that the available output drive types align with the downstream logic interface requirements of the target system architecture.

Supervisors Part Context

This part belongs to the ICL7665 series of supervisory circuits designed for comprehensive power management applications. It complements other Maxim Integrated products by offering multi-channel oversight in a small form factor.
