ICL7665SIBA-T

Supervisors Overview

The ICL7665SIBA-T is a microprocessor voltage monitor featuring dual over/under-voltage detectors. It operates within a supply voltage range of 1.6V to 16V and draws a typical operating current of 3µA. The trip points are externally programmable via resistors for voltages greater than 1.3V. It utilizes an open-drain output and lacks manual reset or watchdog functions. The device is housed in an 8-SOIC package and supports an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Dual voltage detection capability with individually programmable trip points using external resistors
• Ultra-low power consumption with typical operating current of 3µA
• Wide supply voltage operation from 1.6V to 16V while monitoring lower voltage thresholds

Supervisors Applications

• Microprocessor voltage monitoring
• Low-battery detection systems
• Power-fail and brownout detection circuits
• Battery backup switching applications

Supervisors Procurement Notes

Verify the specific suffix 'IBA' against official Renesas documentation to confirm pinout, threshold accuracy, and package dimensions. Confirm RoHS compliance status and lead time requirements directly with authorized distributors, as availability may vary by region. Ensure the selected variant matches the required thermal performance for the intended application environment.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required with low quiescent current. The externally adjustable thresholds allow flexibility for various logic families and battery chemistries. Consider the 8-SOIC package constraints and ensure the open-drain output interface is compatible with the downstream processor input requirements.

Supervisors Part Context

Part of the ICL7665 series, which provides CMOS micropower over/under voltage detection. This family is designed for portable and battery-operated systems where power efficiency is critical. The ICL7665SIBA-T represents a surface-mount version optimized for automated assembly processes.

Supervisors Replacement Considerations

Check for direct equivalents such as the ICL7665SAIBA-T or ICL7665SCBAZA-T. Verify that substitute parts maintain identical threshold adjustability, supply voltage ranges, and package footprints to ensure board compatibility.
