ICL7665SACBAZA

Supervisors Overview

The ICL7665SACBAZA is a CMOS micropower supervisory circuit manufactured by Renesas Electronics Corporation. It functions as a dual-channel voltage detector with adjustable or selectable thresholds, designed to monitor two independent power supply rails. The device operates within a supply voltage range of 1.8 V to 16 V and draws a typical quiescent current of 10 µA. It features an open-drain or open-collector output that asserts a high-active reset signal when monitored voltages fall below or exceed defined limits. Packaged in an 8-SOIC surface-mount case, it supports manual reset functionality and is rated for commercial operating temperatures from 0°C to +70°C.

Supervisors Feature Summary

• Dual-channel monitoring capability for independent voltage supervision
• Adjustable or selectable threshold voltages for flexible configuration
• Low-power CMOS architecture ensuring minimal quiescent current consumption
• Open-drain/open-collector output providing high-active reset signaling

Supervisors Applications

• Portable battery-powered equipment requiring low standby current
• Microprocessor systems needing reliable power-on reset sequences
• Industrial control units monitoring multiple voltage rails
• Communication modules requiring brown-out protection

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance and lead-free specifications against current manufacturing standards. Check for alternate manufacturing site certifications if sourcing from secondary markets. Ensure packaging integrity matches required reel or tube quantities. Validate datasheet revisions to confirm pinout and electrical characteristics remain unchanged.

Supervisors Selection Notes

Select this component when dual-rail supervision with adjustable thresholds is required in a compact SOIC package. Consider the 10 µA quiescent current for battery-sensitive designs. Verify that the open-drain output interface aligns with the system's pull-up requirements. Ensure the 0°C to +70°C temperature range meets environmental constraints. Compare against newer Renesas equivalents if long-term availability is critical.

Supervisors Part Context

This part belongs to the ICL7665 series of micropower voltage detectors originally developed by Intersil and later acquired by Renesas. The series includes variants with fixed or adjustable thresholds and different package options such as PDIP and SOIC. The ICL7665SACBAZA specifically denotes the SOIC-8 package variant with commercial temperature rating. It serves as a legacy solution for power management in embedded systems before modern integrated supervisors became prevalent.

Supervisors Replacement Considerations

Public confirmed substitute part numbers include ICL7665SACBAZ and ICL7665SCBAZA.
