ICL7665BCPA

Supervisors Overview

The ICL7665BCPA is a CMOS micropower voltage detector manufactured by Analog Devices Inc./Maxim Integrated. It features two individually programmable over/under-voltage detectors with an internal bandgap reference, ensuring accurate threshold voltages across the operating supply range of 1.6V to 16V. The device operates from a single supply and requires typically 3µA for operation, making it suitable for battery-powered systems. It provides high or low voltage warnings with settable trip points via external resistors. The component is housed in an 8-pin DIP package.

Supervisors Feature Summary

• Dual independently programmable voltage monitoring channels
• Internal bandgap reference for stable threshold accuracy
• Micropower consumption suitable for battery applications
• Single-supply operation capability

Supervisors Applications

• Battery-operated systems requiring voltage warnings
• Instruments needing settable fault detection thresholds
• Portable electronic devices with power management requirements

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as this specific part number may not meet current environmental standards compared to newer variants. Check datasheet revisions for any pinout or electrical characteristic updates before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when dual-channel voltage supervision is required with adjustable thresholds. Ensure the application supports the specified operating temperature range and supply voltage limits. Consider alternative active versions if lead-free manufacturing is mandatory for the target market.

Supervisors Part Context

This component belongs to the ICL7665 series of micropower voltage supervisors. It serves as a legacy solution for power supply monitoring in analog and mixed-signal circuits. The series is characterized by its flexibility in setting trip points using external resistor networks rather than fixed internal thresholds.

Supervisors Replacement Considerations

ICL7665ACSA+ and ICL7665CSA+ are documented parameter-equivalent alternatives.
