ICL7665ACPA+

Supervisors Overview

The ICL7665ACPA+ is a microprocessor voltage monitor featuring dual overvoltage and undervoltage detection capabilities. It operates within a supply voltage range of 1.6V to 16V while monitoring input voltages from 1.3V upwards. The device draws a typical operating current of 3µA, ensuring low power consumption. It includes an on-board hysteresis mechanism and allows for externally programmable trip points via external resistors. The component utilizes a monolithic, low-power CMOS design and is housed in an 8-pin PDIP package.

Supervisors Feature Summary

• Provides dual independent voltage detectors for precise overvoltage and undervoltage warning signals
• Features externally programmable trip points and hysteresis through simple resistor networks
• Utilizes a low-power monolithic CMOS architecture with minimal quiescent current draw

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix 'CPA+' indicates the lead-free, RoHS-compliant variant of the ICL7665A. Confirm that the package type matches the required 8-pin DIP footprint for your PCB layout. Ensure the external resistor values selected for trip point programming fall within the valid voltage range specifications provided in the official datasheet.

Supervisors Selection Notes

Select this component when dual-channel voltage supervision is required with adjustable thresholds. The ICL7665A variant offers improved threshold accuracy compared to standard versions. Consider the low operating current suitable for battery-powered applications. Verify that the external resistor network can achieve the desired voltage levels within the 1.3V minimum monitoring limit.

Supervisors Part Context

This part belongs to the ICL7665 family of microprocessor supervisors manufactured by Analog Devices (Maxim Integrated).
