ICL7665SIBAZ

Supervisors Overview

The ICL7665SIBAZ is a dual-channel voltage supervisor manufactured by Renesas Electronics Corporation, designed for monitoring system power integrity. It operates within an input voltage range of 1.6V to 16V and features adjustable trip voltages for precise threshold detection. The device provides open-drain outputs with high-active reset signals, suitable for CMOS logic interfaces. It supports battery backup switching functionality and lacks manual reset or watchdog timer capabilities. Operating reliably across a temperature range of -40°C to +85°C, it is housed in an 8-SOIC surface-mount package.

Supervisors Feature Summary

• Dual independent voltage monitoring channels with adjustable trip thresholds
• Open-drain output configuration compatible with standard logic families
• Integrated battery backup switching mechanism for data retention
• High-active reset signal generation upon undervoltage detection

Supervisors Applications

• Portable instrumentation systems requiring reliable power supervision
• Memory power backup circuits ensuring data integrity during outages
• Battery-operated devices needing low-voltage cutoff protection
• Pocket pagers and portable computers utilizing multi-rail power architectures

Supervisors Procurement Notes

Verify the specific suffix 'IBA' against official Renesas documentation to confirm pinout compatibility and thermal characteristics. Ensure the selected variant matches the required adjustable threshold specifications rather than fixed versions. Cross-reference the 8-SOIC package dimensions with PCB footprint requirements prior to procurement to prevent assembly errors.

Supervisors Selection Notes

Select this component when dual-channel supervision with programmable thresholds is required for complex power rails. Consider the open-drain output limitation for pull-up resistor integration in the design phase. Evaluate the absence of a watchdog timer if system fault recovery requires additional external circuitry beyond simple voltage monitoring.

Supervisors Part Context

This part belongs to the ICL7665S supervisory circuit family, which focuses on multi-voltage monitoring solutions. Unlike charge pump regulators such as the ICL7660 series, this device strictly handles voltage detection and reset signaling. It serves as a critical interface between power management stages and digital control logic in embedded applications.
