ICL7665SCPAZ

Supervisors Overview

The ICL7665SCPAZ is a microprocessor voltage monitor manufactured by Renesas Electronics Corporation. It provides dual overvoltage and undervoltage detection for system power rails. The device operates within a supply voltage range of 1.8V to 16V, with monitoring thresholds programmable via external resistors for voltages above 1.3V. It features a typical operating current of 3µA and includes on-board hysteresis. The component is housed in an 8-pin PDIP package and supports manual reset functionality.

Supervisors Feature Summary

• Dual independent voltage detectors with externally programmable trip points
• Low-power CMOS design with minimal quiescent current consumption
• Integrated hysteresis to prevent output oscillation during threshold transitions

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix 'SCPAZ' against official Renesas documentation to confirm the PDIP-8 package and commercial temperature range. Ensure compatibility with existing board layouts designed for through-hole DIP-8 components. Confirm RoHS compliance status as per the latest manufacturer declarations before finalizing procurement orders.

Supervisors Selection Notes

Select this component when dual-channel voltage supervision is required for low-power embedded applications. The externally adjustable thresholds allow flexibility for various rail voltages. Consider the PDIP package constraint if surface-mount space is limited or if through-hole assembly processes are mandated by manufacturing requirements.

Supervisors Part Context

This part belongs to the ICL7665 family of microprocessor supervisors. It serves as a dedicated circuit for detecting abnormal power conditions. The series is widely used in industrial and consumer electronics where reliable power integrity is critical for processor stability and data preservation.

Supervisors Replacement Considerations

Direct substitutes include the ICL7665SACPAZ and ICL7665SCBAZ. Verify pinout compatibility and electrical specifications before substitution. Note that some variants may differ in package type or temperature rating.
