ICL7665SACBA

Supervisors Overview

The ICL7665SACBA is a dual-channel voltage supervisor manufactured by Renesas Electronics Corporation. It monitors two independent supply voltages and provides reset signals when thresholds are exceeded. The device operates within a supply voltage range of 1.8 V to 16 V. It features adjustable or selectable threshold voltages, allowing customization for specific application requirements. The component utilizes an open-drain or open-collector output configuration with active-high reset functionality. It is housed in an 8-SOIC surface-mount package and is designed for industrial temperature ranges.

Supervisors Feature Summary

• Dual-channel monitoring capability for independent voltage supervision
• Adjustable or selectable threshold voltage settings for flexible design integration
• Active-high reset output with open-drain/open-collector configuration

Supervisors Applications

• Multi-rail power system supervision in embedded controllers
• Voltage monitoring for microprocessor and FPGA power rails
• Industrial control systems requiring redundant voltage detection

Supervisors Procurement Notes

Verify the current lifecycle status before procurement as this part may be obsolete. Confirm RoHS compliance requirements against project specifications, noting potential non-compliance in some records. Ensure the 8-SOIC package footprint matches the PCB layout. Validate that the active-high reset logic aligns with the target system's input requirements. Check for available parameter-equivalent alternatives if original stock is unavailable.

Supervisors Selection Notes

Select this component when dual-voltage supervision with adjustable thresholds is required. Ensure the operating voltage range covers the minimum and maximum supply levels of the monitored circuits. Verify that the open-drain output can drive the necessary load impedance. Consider the thermal performance within the specified operating temperature range. Confirm compatibility with the system's reset timing requirements.
