ICL7665BC

Supervisors Overview

The ICL7665BC is a dual-channel voltage supervisor manufactured by Analog Devices Inc./Maxim Integrated. It monitors two independent input voltages to detect overvoltage and undervoltage conditions, providing active high, active low, or open-drain reset outputs. The device operates within a supply voltage range of 2V to 16V and features a typical quiescent current of 15µA. It includes a backup battery switch function for maintaining system state during power transitions. The component is housed in an 8-SOIC package and supports a junction temperature range from 0°C to +70°C.

Supervisors Feature Summary

• Dual-channel voltage monitoring with selectable threshold detection
• Configurable reset output polarity including active high, active low, and open-drain options
• Integrated backup battery switch for seamless power source transition

Supervisors Applications

• Portable electronic devices requiring multi-rail power supervision
• Battery-powered systems needing backup switching functionality
• Industrial control circuits monitoring critical voltage levels

Supervisors Procurement Notes

Verify the specific suffix (e.g., CSA) against the datasheet to confirm package type and temperature grade. Confirm RoHS compliance status as older batches may differ. Check manufacturer lifecycle notices for obsolescence warnings before finalizing procurement plans.

Supervisors Selection Notes

Select this component when dual independent voltage rails require simultaneous supervision. Ensure the required reset logic polarity matches the available output configurations. Verify that the operating temperature range aligns with the intended environmental conditions.

Supervisors Part Context

This part belongs to the ICL7665 series of supervisory circuits designed for low-power applications. It complements other Maxim Integrated PMIC solutions by offering precise voltage monitoring without complex external components. The series is widely used in consumer electronics and industrial instrumentation.

Supervisors Replacement Considerations

Direct parameter-equivalent replacements include ICL7665ACSA+ and ICL7665CSA+. Verify pin compatibility and threshold accuracy when substituting.
