ICL7665SCBA-T

Supervisors Overview

The ICL7665SCBA-T is a CMOS micropower voltage detector manufactured by Renesas Electronics. It features dual over/under-voltage detection capabilities with an open-drain output type and no manual reset function. The device operates within a supply voltage range of 1.6 V to 16 V, consuming only 2.9 µA of working power current. It offers high accuracy of 2% and includes battery backup switching functionality. The component is housed in an SOIC-8 surface-mount package and supports an operating temperature range from 0°C to +70°C.

Supervisors Feature Summary

• Dual-channel voltage monitoring for simultaneous over and under-voltage detection
• CMOS technology enabling ultra-low micropower consumption
• Open-drain output configuration compatible with various logic families
• Integrated battery backup switch for seamless power transition

Supervisors Applications

• Portable instrumentation systems requiring low standby current
• Memory power backup circuits ensuring data integrity during power loss
• Battery-operated devices needing efficient voltage supervision
• Charging systems monitoring input voltage stability

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging if required by assembly equipment. Confirm RoHS compliance status through official datasheets as manufacturing sites may vary. Check for End-of-Life (EOL) notices or obsolescence warnings from Renesas, as this family has faced discontinuation announcements. Ensure the selected variant matches the required thermal grade and package dimensions for PCB layout compatibility.

Supervisors Selection Notes

Select this component when dual independent voltage thresholds are necessary within a single compact package. The low quiescent current makes it suitable for battery-powered applications where energy efficiency is critical. Verify that the open-drain output aligns with the downstream circuit's pull-up requirements. Consider the operating temperature range to ensure reliability in the intended environmental conditions without requiring extended grade variants.

Supervisors Part Context

The ICL7665 series belongs to Renesas' portfolio of micropower supervisory circuits, originally developed by Intersil. These devices are designed to monitor power rails in portable electronics and industrial systems. The SCBA-T designation specifically denotes the SOIC-8 surface-mount package with tape-and-reel shipping format, facilitating automated pick-and-place manufacturing processes.

Supervisors Replacement Considerations

Publicly confirmed substitute part numbers include ICL7665SACBAZ. Verify pinout compatibility and electrical specifications before substitution.
