ICL7665CPA+

Supervisors Overview

The ICL7665CPA+ is a dual-channel power supply support circuit manufactured by Analog Devices Inc./Maxim Integrated. It functions as a micropower over/under voltage detector housed in an 8-pin PDIP package. The device monitors two independent input voltages, providing active high and active low outputs for fault detection. It operates within a supply voltage range of 1.6 V to 16 V with a typical quiescent current of 3 µA. The unit supports adjustable trip points via external resistors and features an internal bandgap reference for accurate threshold determination across the operating temperature range of 0°C to +70°C.

Supervisors Feature Summary

• Dual-channel monitoring capability with individually programmable overvoltage and undervoltage thresholds using external resistor networks.
• Micropower CMOS architecture designed for battery-operated systems, requiring minimal quiescent current during operation.
• Integrated internal bandgap reference ensures stable and accurate voltage detection performance across the full supply voltage range.

Supervisors Applications

• Battery operated systems requiring low voltage warnings
• Portable instrumentation with memory power back-up
• Charging systems needing voltage supervision

Supervisors Procurement Notes

Verify the specific suffix 'CPA+' against official manufacturer documentation to confirm lead-free compliance and package type. Confirm availability status as distribution channels may list obsolete or limited stock variants. Ensure the selected component matches the required PDIP-8 through-hole mounting style for your PCB design.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required with low power consumption constraints. The adjustable trip points allow customization for specific system thresholds without changing the IC. Consider the PDIP-8 package if through-hole assembly is preferred over surface mount alternatives like the CSA variant.

Supervisors Part Context

This part belongs to the ICL7665 series of supervisory circuits from Maxim Integrated. It is a CMOS micropower device intended for applications requiring reliable voltage monitoring with minimal impact on system battery life. The series includes various package options and temperature grades to suit different industrial and commercial requirements.

Supervisors Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include ICL7665ACSA+ and ICL7665CSA+. Verify pin compatibility and package dimensions before substitution. Note that some variants may differ in RoHS compliance or operating temperature ranges.
