ICL7665SAIBA-T

Supervisors Overview

The ICL7665SAIBA-T is a CMOS micropower over/under voltage detector manufactured by Renesas Electronics. It operates within a supply voltage range of 1.8 V to 16 V and consumes typically 3 µA during operation. The device features two independent monitoring inputs with adjustable threshold voltages, specifically set at 1.275 V for undervoltage and 1.325 V for overvoltage detection. It provides an active low output signal and is housed in an 8-pin SOIC surface-mount package. The component supports a battery backup switching function and functions reliably across an industrial temperature range from -40 °C to +85 °C.

Supervisors Feature Summary

• Dual-channel voltage monitoring with independently adjustable trip points for precise power supervision
• Ultra-low quiescent current consumption suitable for battery-powered applications
• Integrated battery backup switching capability to maintain system state during power transitions

Supervisors Applications

• Portable electronic devices requiring extended battery life
• Industrial control systems needing reliable power fault detection
• Embedded systems with critical voltage supervision requirements

Supervisors Procurement Notes

Verify the specific suffix configuration against official Renesas documentation to ensure compatibility with required operating temperatures and package variants. Confirm availability status as distribution channels may list limited stock or obsolete status for certain manufacturing lots. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Supervisors Selection Notes

Select this component when dual-channel voltage supervision with adjustable thresholds is required in a compact surface-mount form factor. Ensure the application environment falls within the specified -40 °C to +85 °C operating range. Verify that the 1.8 V minimum supply voltage aligns with the system's lowest operational rail. Consider the active low output polarity when interfacing with downstream logic circuits.
