ICL7665SAIBA

Supervisors Overview

The ICL7665SAIBA is a CMOS micropower over/under voltage detector manufactured by Renesas Electronics Corporation. It features two individually programmable voltage detectors on a single chip, designed for battery-operated systems and instruments. The device operates within a supply voltage range of 1.8 V to 16 V and consumes typically 3 μA of current. It utilizes a PDIP-8 through-hole package and supports an operating temperature range from -40 °C to +85 °C. The output type is active low, providing reset functionality without manual intervention or watchdog timers.

Supervisors Feature Summary

• Dual independently programmable voltage detection channels integrated on a single CMOS chip
• Ultra-low power consumption suitable for battery-operated applications
• Active low output signal generation for system reset control

Supervisors Applications

• Battery operated systems
• Portable instrumentation
• Memory power back-up circuits

Supervisors Procurement Notes

Verify component authenticity and datasheet revisions prior to integration. Confirm package compatibility with PCB footprint requirements. Check for end-of-life status or obsolescence notices from the manufacturer. Ensure supply chain stability for long-term production needs.

Supervisors Selection Notes

Select this component when dual-channel voltage monitoring with adjustable thresholds is required in space-constrained designs. Consider the PDIP-8 package for through-hole assembly processes. Evaluate power budget constraints against the typical microampere standby current specification.
