ICL7665BCSA+

Supervisors Overview

The ICL7665BCSA+ is a dual-channel voltage supervisor manufactured by Analog Devices Inc./Maxim Integrated, housed in an 8-SOIC surface-mount package. It monitors two input voltages with adjustable or selectable thresholds and provides active high, active low, and open-drain outputs. The device operates within a supply voltage range of 1.6 V to 16 V and maintains a typical quiescent current of 15 µA. It features a reset timeout of less than 1 ms minimum and ensures accuracy within 2%. The component supports battery backup switching and functions reliably across an operating temperature range of 0°C to +70°C.

Supervisors Feature Summary

• Dual-channel voltage monitoring with selectable threshold options for flexible system supervision
• Multi-output configuration providing active high, active low, and open-drain signals for diverse logic compatibility
• Ultra-low power consumption with 15 µA operating current to extend battery life in portable applications

Supervisors Applications

• Battery-powered systems requiring voltage level supervision
• Microprocessor reset circuits in embedded controllers
• Industrial automation equipment monitoring critical power rails

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact threshold configurations and output states. Ensure the procurement source provides valid traceability and RoHS compliance certificates. Confirm that the 8-SOIC package dimensions match your PCB footprint requirements. Check for any recent product change notices regarding manufacturing site transfers or material updates.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required within a compact surface-mount form factor. Consider the 15 µA quiescent current for battery-sensitive designs. Evaluate the available output types (active high/low/open drain) against your microcontroller input requirements. Verify that the 1.6 V to 16 V supply range covers your system's operational voltage envelope.

Supervisors Part Context

This part belongs to the ICL7665 series of supervisory circuits from Maxim Integrated, now part of Analog Devices. The series is designed for reliable power management in industrial and consumer electronics. The B-grade variant typically denotes specific threshold tolerances compared to other commercial grades within the same family line.

Supervisors Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the ICL7665ACSA+ and ICL7665CSA+. These alternatives share the same 8-SOIC package and core functionality but may differ in specific threshold accuracies or temperature ranges.
