ICL7665SCBAZA-T

Supervisors Overview

The ICL7665SCBAZA-T is a CMOS micropower voltage detector manufactured by Renesas Electronics. It monitors two independent input voltages for overvoltage and undervoltage conditions within a supply range of 1.6 V to 16 V. The device features adjustable or selectable threshold voltages, specifically an overvoltage threshold of 1.4 V and an undervoltage threshold of 1.2 V for both channels. It operates with a low quiescent current of 10 µA and functions reliably across a commercial temperature range from 0°C to +70°C. The component is housed in an 8-SOIC surface-mount package.

Supervisors Feature Summary

• Dual-channel monitoring capability for simultaneous detection of overvoltage and undervoltage events on separate inputs.
• CMOS technology ensures micropower consumption with a typical operating current of 10 µA.
• Configurable threshold settings allow selection between fixed or adjustable voltage detection levels.

Supervisors Applications

• Portable battery-powered equipment requiring efficient power management
• Microprocessor reset circuits in embedded systems
• Industrial control systems needing reliable voltage supervision

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm that the 'SC' variant corresponds to the specified 0°C to +70°C operating temperature range rather than the industrial grade. Ensure compatibility with existing PCB footprints for the 8-SOIC package before finalizing procurement plans.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required in space-constrained designs. The 8-SOIC package offers a compact solution compared to through-hole alternatives. Consider the 10 µA quiescent current for applications where minimizing standby power drain is critical for overall system efficiency.

Supervisors Part Context
