ICL7665SAIBA

Supervisors Overview

The ICL7665SAIBA is a CMOS micropower over/under voltage detector manufactured by Renesas Electronics (formerly Intersil/Harris). It features two independent monitoring channels with adjustable trip points, allowing for precise threshold configuration. The device operates within a supply voltage range of 1.8 V to 16 V and consumes typically 3 µA of quiescent current. It provides an active-low open-drain output signal when monitored voltages exceed or fall below set limits. Packaged in an 8-pin PDIP format, it supports through-hole mounting and functions without manual reset or watchdog timer capabilities.

Supervisors Feature Summary

• Dual-channel voltage monitoring with independently adjustable trip points
• Ultra-low power consumption suitable for battery-operated applications
• Active-low open-drain output signaling for fault detection
• CMOS technology ensuring compatibility with standard logic interfaces

Supervisors Applications

• Portable instrumentation systems requiring low-power supervision
• Memory power backup circuits needing undervoltage protection
• Battery-operated devices utilizing over/under voltage warnings
