ISL88708IB829Z

Supervisors Overview

The ISL88708IB829Z is a microprocessor supervisor integrated circuit manufactured by Renesas Electronics Corporation, formerly Intersil. It monitors a single power supply channel with a fixed threshold voltage of 2.92V. The device provides open-drain and push-pull outputs for reset signaling. It features a minimum reset timeout of 140ms and supports both high-active and low-active reset configurations. Operating within a temperature range of -40°C to +85°C, it is housed in an 8-SOIC surface-mount package.

Supervisors Feature Summary

• Integrates watchdog timer functionality for system reliability
• Includes manual reset input capability
• Features adjustable power-on reset thresholds
• Provides power-fail comparator output

Supervisors Applications

• Industrial control systems
• Microprocessor power supply monitoring
• Battery function supervision in embedded systems

Supervisors Procurement Notes

Verify the specific suffix IB829Z to confirm the 2.92V threshold voltage, as other suffixes indicate different voltages. Confirm package type matches design requirements. Check component status as this series may be discontinued or subject to product change notices. Ensure compatibility with existing PCB footprint and thermal management strategies during integration.

Supervisors Selection Notes

Select this component when a fixed 2.92V threshold is required for precise power rail monitoring. Choose between open-drain or push-pull outputs based on interface requirements. Consider the 140ms minimum timeout for appropriate reset timing. Verify that the SOIC-8 package fits the available board space and manufacturing capabilities.

Supervisors Part Context

The ISL88708 belongs to a family of microprocessor supervisors designed for monitoring power-supply and battery functions. It shares functional similarities with models like the ISL88705, ISL88706, and ISL88707. These devices are engineered for high reset threshold accuracy and low power consumption in microprocessor systems.

Supervisors Replacement Considerations

Substitutes include ISL88708IB826Z (2.63V threshold) and ISL88708IP831Z (3.09V threshold). Verify threshold voltage compatibility before replacement. Ensure pinout and package dimensions remain identical for direct substitution.
