ICL7665BESA

Supervisors Overview

The ICL7665BESA is a two-channel voltage monitor IC from the ICL7665 series, manufactured by Analog Devices Inc./Maxim Integrated. It provides dual over/undervoltage detection for system supervision. The device operates within a supply voltage range up to 16 V and features a threshold voltage of 1.3 V with an accuracy of 2%. It utilizes an open-drain output configuration and includes battery backup switching capabilities. The component is designed for surface-mount installation in SOIC-Narrow-8 packages and functions reliably across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Dual-channel monitoring architecture for simultaneous overvoltage and undervoltage detection
• Integrated battery backup switch functionality for continuous supervision during power transitions
• Open-drain output interface compatible with various logic families

Supervisors Applications

• Microprocessor voltage supervision
• Embedded system power management
• Edge computing hardware monitoring

Supervisors Procurement Notes

Verify current availability status as this specific part number may be discontinued or subject to limited supply conditions. Confirm that the required package type and electrical specifications match the design requirements before procurement. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure compatibility with existing PCB footprints and thermal management strategies.

Supervisors Selection Notes

Select this component when dual independent voltage rails require simultaneous supervision without external comparator circuitry. The fixed threshold characteristics simplify design implementation compared to adjustable variants. Consider the operating temperature range and package constraints relative to the target application environment. Verify that the open-drain output drive capability meets the downstream logic input requirements.

Supervisors Part Context

This component belongs to the ICL7665 family of supervisory circuits, which are widely used for ensuring reliable operation of digital systems by detecting abnormal power conditions. The series offers various pinout and threshold options to accommodate different system architectures. As a legacy Maxim Integrated product now under Analog Devices, it represents a standard solution for basic power monitoring tasks in industrial and consumer electronics.

Supervisors Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include ICL7665ACSA+ and ICL7665CSA+. These alternatives offer similar dual-channel monitoring functionality but may differ in packaging or specific electrical tolerances. Verify pin compatibility and threshold values before substitution.
