ICL7665BCTV

Supervisors Overview

The ICL7665BCTV is a microprocessor voltage monitor manufactured by Analog Devices Inc./Maxim Integrated. It provides dual overvoltage and undervoltage detection for system supervision. The device operates within a supply voltage range of 1.6V to 16V, monitoring input voltages from 1.3V upwards. It features externally programmable trip points via external resistors and includes on-board hysteresis. The typical operating current is 3µA. The component is housed in an 8-lead TO-99 metal can package.

Supervisors Feature Summary

• Dual comparator architecture with precision internal reference for accurate voltage monitoring
• Externally programmable trip points allow customization for specific voltage thresholds
• Low-power CMOS design ensures minimal quiescent current consumption during operation

Supervisors Applications

• Microprocessor voltage monitoring systems
• Low-battery detection circuits
• Power-fail and brownout detection applications
• Battery backup switching logic
• Over/undervoltage protection interfaces

Supervisors Procurement Notes

Verify the specific suffix BCTV corresponds to the TO-99-8 metal can package configuration. Confirm that the threshold accuracy requirements align with the standard ICL7665 specifications rather than the improved A-grade version. Ensure compatibility with the 1.6V to 16V supply range for your target application environment.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required with low power consumption. The external resistor programming offers flexibility for non-standard voltage thresholds. Consider the TO-99 package constraints for board space and thermal management compared to surface-mount alternatives like the CSA variant.

Supervisors Part Context

This part belongs to the ICL7665 family of microprocessor supervisors. It serves as a core monitoring element in embedded systems requiring reliable power integrity checks. The family includes variants with different packages and accuracy grades, such as the ICL7665A which guarantees 2% threshold accuracy across temperature ranges.
