ICL7665AESA+T

Supervisors Overview

The ICL7665AESA+T is a voltage monitor circuit featuring dual over/undervoltage detection capabilities. It operates within a supply voltage range of up to 16 V and maintains an accuracy of 2%. The device monitors two input channels with specific threshold voltages at 1.325 V and 1.375 V, utilizing a fixed threshold of 1.3 V. It draws a typical operating current of 15 uA and dissipates power up to 471 mW. Designed for surface mount installation in SOIC-Narrow-8 packages, it functions reliably across temperatures from -40°C to +85°C without manual reset or watchdog timer features.

Supervisors Feature Summary

• Dual-channel monitoring architecture supporting simultaneous overvoltage and undervoltage detection
• Low quiescent current consumption suitable for battery-powered applications
• Integrated backup battery switch functionality for continuous monitoring during power transitions

Supervisors Applications

• Portable electronic devices requiring low-power voltage supervision
• Battery-operated systems needing backup switching protection
• Industrial control circuits with multiple voltage rails

Supervisors Procurement Notes

Verify the exact suffix configuration against official Analog Devices documentation to ensure compatibility with required threshold settings and package variants. Confirm RoHS compliance status through manufacturer declarations prior to integration. Cross-reference lead times and availability directly with authorized distributors as stock levels fluctuate. Ensure the selected variant matches the specific thermal and electrical requirements of the target application environment.

Supervisors Selection Notes

Select this component when dual independent voltage thresholds are necessary for system supervision. Consider the 15 uA standby current for energy-sensitive designs. Verify that the SOIC-Narrow-8 footprint aligns with PCB layout constraints. Evaluate the absence of a manual reset feature against system recovery requirements. Compare performance metrics against alternative supervisors if higher precision or additional channels are needed.

Supervisors Part Context
