ICL7665SAIBA-T-HC

Supervisors Overview

The ICL7665SAIBA-T-HC is a CMOS micropower over/under voltage detector manufactured by Renesas Electronics (formerly Harris Corporation). It monitors two independent supply voltages and provides active low outputs when thresholds are exceeded. The device operates within a supply voltage range of 1.8 V to 16 V, with a typical quiescent current of 10 µA. It features adjustable threshold voltages for both overvoltage and undervoltage detection, packaged in an 8-pin PDIP format suitable for through-hole mounting.

Supervisors Feature Summary

• Dual-channel voltage monitoring capability for independent power rails
• Adjustable threshold settings for customized over/under voltage detection
• Low power consumption design with microampere-level standby current

Supervisors Applications

• Battery-powered systems requiring low quiescent current
• Portable electronic devices with multiple voltage domains
• Industrial control circuits needing reliable power supervision

Supervisors Procurement Notes

Verify the manufacturer origin as this part number originates from Harris Corporation, now part of Renesas Electronics. Confirm RoHS compliance status as historical data may vary. Check availability since older Harris-branded components may be discontinued or limited stock. Ensure the specific suffix matches the required package and temperature grade for your application.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required with adjustable thresholds. Consider the 1.8 V to 16 V operating range and 10 µA quiescent current for low-power designs. Verify that the PDIP-8 through-hole package fits your PCB layout constraints compared to surface-mount alternatives like the SOIC variants.

Supervisors Part Context

This component belongs to the ICL7665 series of micropower supervisors originally developed by Harris Semiconductor. The series includes various packages and threshold options. The SAIBA variant specifically denotes the PDIP-8 package with adjustable thresholds. This lineage continues under Renesas Electronics after the acquisition of Harris's semiconductor division.

Supervisors Replacement Considerations

ICL7665ACSA+T offers similar dual-channel monitoring in an SOIC-8 package with fixed thresholds. ICL7665SACPAZ provides a PDIP-8 option but may have different commercial temperature ratings. Verify pin compatibility and threshold adjustability when substituting.
