ICL7665AEPA+

Supervisors Overview

The ICL7665AEPA+ is a supervisory voltage monitor circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features dual over/undervoltage detection capabilities with a threshold voltage of 1.3 V and an accuracy of 2%. The device operates within a power supply range up to 16 V and draws a working current of 15 uA. It supports battery backup switching and provides active high, active low, and open drain output types. The component is housed in an 8-PDIP package and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Dual-channel voltage monitoring for simultaneous overvoltage and undervoltage detection
• Battery backup switch functionality to maintain system integrity during power transitions
• Flexible output configuration supporting active high, active low, and open drain signals

Supervisors Applications

• Portable electronic devices requiring low-power supervision
• Battery-operated systems needing backup switching protection
• Industrial control circuits demanding precise voltage monitoring

Supervisors Procurement Notes

Verify the specific suffix 'P' confirms the PDIP package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the operating environment remains within the specified -40°C to +85°C thermal limits. Cross-reference the exact part number with authorized distributors to avoid counterfeit components. Validate that the 1.3 V threshold aligns with your system's voltage requirements.

Supervisors Selection Notes

Select this component when dual independent voltage channels are required for comprehensive system supervision. The low quiescent current makes it suitable for energy-constrained applications. Consider the PDIP package for through-hole mounting requirements. Verify that the 2% accuracy meets your design tolerance specifications. Ensure the input voltage does not exceed the 16 V maximum rating.

Supervisors Part Context

This part belongs to the ICL7665A series of supervisory circuits designed for reliable voltage monitoring. It complements other Maxim Integrated products focused on power management and system protection. The series is known for integrating multiple monitoring functions into compact packages. It serves as a critical component for ensuring stable operation in sensitive electronic environments.

Supervisors Replacement Considerations

The ICL7665AEPA+ is functionally compatible with the ICL7665AESA+T variant, differing primarily in packaging type (PDIP vs. SOIC). Verify pin compatibility and thermal performance when substituting between package styles. No direct cross-model replacements are officially documented beyond package variations.
