ICL7665SACBAZA-T

Supervisors Overview

The ICL7665SACBAZA-T is a CMOS micropower supervisory circuit manufactured by Renesas Electronics Corporation. It integrates two individually programmable voltage detectors on a single chip, designed for monitoring power supply rails in battery-operated systems. The device operates within a supply voltage range of 1.8 V to 16 V and features an open-drain output with high-active reset functionality. It is housed in an 8-SOIC surface-mount package and supports an industrial operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates two independently programmable over/under voltage detectors on a single CMOS chip
• Features low quiescent current consumption suitable for battery-powered applications
• Provides open-drain output configuration with active-high reset signal

Supervisors Applications

• Battery-operated portable instruments requiring power supervision
• Portable computers and handheld devices
• Industrial control systems with multiple voltage rails

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as documentation may vary by production batch. Check for obsolescence notices or lifecycle changes from Renesas, as this component series has undergone manufacturing transitions. Ensure the selected variant matches the required threshold voltage settings for your design.

Supervisors Selection Notes

Select this component when dual-channel voltage monitoring is required with minimal power consumption. Compare threshold voltage adjustability against fixed-voltage alternatives if precise trip points are needed. Consider the SOIC-8 package dimensions for PCB layout constraints. Verify that the open-drain output interface is compatible with the downstream logic levels of the monitored system.

Supervisors Part Context

This part belongs to the ICL7665S family of micropower voltage supervisors. It shares functional similarities with other variants like ICL7665SAIBAZA-T but differs in specific threshold configurations and packaging options. The family is designed to replace older discrete voltage detection solutions with integrated, low-power CMOS alternatives.

Supervisors Replacement Considerations

ICL7665SACBAZ is listed as a parameter-equivalent alternative.
