ICL7665ACSA+

Supervisors Overview

The ICL7665ACSA+ is a dual-channel voltage monitor integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within an input voltage range of 2V to 16V and features adjustable or selectable overvoltage and undervoltage thresholds, with specific threshold options including 1.325V and 1.375V. The device provides active high, active low, and open drain outputs for flexible system integration. It consumes a typical supply current of 15µA and maintains accuracy within 2%. Designed for surface-mount installation in an 8-SOIC package, it functions reliably across a commercial temperature range of 0°C to +70°C.

Supervisors Feature Summary

• Dual-channel monitoring capability for independent supervision of two distinct power rails
• Configurable output states supporting active high, active low, and open drain configurations
• Adjustable or selectable voltage thresholds allowing customization for specific application requirements
• Ultra-low quiescent current consumption suitable for battery-powered or energy-efficient designs

Supervisors Applications

• Supervision of multiple power rails in embedded systems
• Overvoltage and undervoltage detection in portable electronic devices
• System reset generation in microcontroller-based architectures
• Battery backup switching circuits requiring voltage level monitoring

Supervisors Procurement Notes

Verify the manufacturer designation as Analog Devices Inc./Maxim Integrated when sourcing this component. Confirm the suffix indicates RoHS compliance and tape-and-reel packaging if applicable. Ensure the order matches the specific pinout and electrical characteristics defined in the official datasheet. Cross-reference the full part number to distinguish from non-RoHS or legacy variants within the same family.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required with configurable output logic levels. Consider the 2V minimum operating voltage and 16V maximum limit against your system's rail specifications. Evaluate the 15µA supply current against total power budget constraints. Verify that the 8-SOIC package dimensions fit the available PCB real estate and thermal requirements.

Supervisors Part Context

This device belongs to the ICL7665 series of supervisory circuits designed for power management applications. It serves as a dedicated voltage monitor rather than a regulator or converter. The series supports various package options and threshold configurations to address diverse industrial and consumer electronics needs. It complements other PMIC components by providing essential fault detection and system protection functions.

Supervisors Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the ICL7665BCSA+ and ICL7665CSA+. These alternatives offer similar dual-channel monitoring functionality but may differ in manufacturing lot or specific environmental certifications. Verify compatibility with existing board layouts and electrical parameters before substitution.
