ICL7665AESA+

Supervisors Overview

The ICL7665AESA+ is a voltage monitor circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for dual over/undervoltage detection. It operates within a supply voltage range of up to 16 V and features a threshold voltage of 1.3 V with an accuracy of 2%. The device supports active high, active low, and open drain output types. It consumes a working power supply current of 15 uA and dissipates up to 471 mW. The component is housed in an SOIC-Narrow-8 package and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides dual independent monitoring channels for simultaneous overvoltage and undervoltage detection.
• Offers flexible output configurations including active high, active low, and open drain options.
• Integrates battery backup switching functionality to maintain monitoring during power transitions.

Supervisors Applications

• Monitoring critical power rails in embedded systems requiring dual threshold supervision.
• Battery-powered devices utilizing backup switching capabilities for uninterrupted operation.
• Industrial control circuits operating within extended temperature environments.

Supervisors Procurement Notes

Verify the specific suffix and manufacturer designation when sourcing this component, as availability may vary between distributors. Confirm that the requested unit matches the exact pinout and electrical specifications listed in the official datasheet. Ensure compliance with RoHS requirements if applicable to your assembly process. Cross-reference the part number with authorized suppliers to avoid counterfeit components.

Supervisors Selection Notes

Select this component when dual-channel voltage supervision is required without manual reset or watchdog timer functionality. Consider the 15 uA quiescent current for low-power applications. Evaluate the available output types against the downstream logic requirements. Verify that the 1.3 V threshold aligns with the target monitoring levels. Check thermal dissipation limits relative to the expected operating conditions.

Supervisors Part Context

This part belongs to the ICL7665A series of supervisory circuits from Analog Devices Inc./Maxim Integrated. It is distinct from other ICL766x variants which may offer different channel counts or additional features like watchdog timers. The + suffix typically indicates lead-free and RoHS-compliant manufacturing standards compared to older non-suffixed versions.
