ICL7665ACPA

Supervisors Overview

The ICL7665ACPA is a microprocessor voltage monitor manufactured by Analog Devices Inc./Maxim Integrated, housed in an 8-PDIP package. It provides dual overvoltage and undervoltage detection with externally programmable trip points via external resistors. The device operates from a supply voltage range of 1.6V to 16V while monitoring input voltages starting from 1.3V. It features on-board hysteresis and draws a typical operating current of only 3µA. The component utilizes a monolithic, low-power CMOS design suitable for battery-powered applications.

Supervisors Feature Summary

• Provides dual independent voltage detectors for overvoltage and undervoltage warning
• Features externally programmable trip points and hysteresis via external resistors
• Operates with ultra-low power consumption of 3µA typical operating current
• Supports wide supply voltage range from 1.6V to 16V

Supervisors Applications

• Microprocessor voltage monitoring
• Low-battery detection systems
• Power-fail and brownout detection circuits
• Battery backup switching fault monitoring

Supervisors Procurement Notes

Verify the specific suffix 'CPA' indicates the PDIP package variant when sourcing. Confirm RoHS compliance status as older Maxim parts may vary. Check for obsolescence notices or lifecycle status before finalizing procurement plans. Ensure external resistor values are calculated correctly for the desired threshold voltages.

Supervisors Selection Notes

Select this component when dual-channel voltage supervision is required with minimal quiescent current. The externally adjustable thresholds allow flexibility for various rail voltages above 1.3V. Consider the PDIP package for through-hole prototyping or high-reliability manual assembly environments where surface mount options are unsuitable.

Supervisors Part Context

This part belongs to the ICL7665 family of micropower voltage monitors. It serves as a critical supervisory element in embedded systems, ensuring stable operation by detecting abnormal power conditions. The A-grade variant typically offers improved threshold accuracy compared to standard industrial grades.

Supervisors Replacement Considerations

ICL7665ACSA+ is listed as a parameter equivalent SMD alternative. Verify pin compatibility and package differences when transitioning from DIP to SOIC formats.
