ISL88708IB831Z-TK

Supervisors Overview

The ISL88708IB831Z-TK is a microprocessor supervisor integrated circuit manufactured by Renesas Electronics Corporation. It features a watchdog timer, power-fail comparator, manual reset input, and adjustable power-on reset with a threshold of 3.09V. The device provides a reset output with a minimum timeout of 140ms. It operates within a temperature range of -40°C to 85°C and is housed in an 8-lead SOIC package.

Supervisors Feature Summary

• Integrates a watchdog timer for system monitoring
• Includes a power-fail comparator for voltage supervision
• Supports manual reset functionality via dedicated input
• Features adjustable power-on reset threshold

Supervisors Applications

• Industrial control systems
• Embedded computing platforms
• Communication equipment power management

Supervisors Procurement Notes

Verify the specific suffix IB831Z-TK against official Renesas documentation to confirm tape-and-reel packaging and exact threshold voltage specifications. Ensure compatibility with existing board layouts and thermal requirements before procurement, as component availability may vary due to lifecycle status.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog and manual reset capabilities is required. The 3.09V threshold suits applications needing precise voltage monitoring. Consider the SOIC-8 package for surface-mount assembly constraints and the specified industrial temperature range for environmental robustness.

Supervisors Part Context

This part belongs to the ISL8870x series of microprocessor supervisors. It shares functional similarities with other variants in the family, differing primarily in threshold voltages, package types, and packaging formats. The series is designed for reliable system reset generation in complex digital environments.

Supervisors Replacement Considerations

Cross-reference with ISL88708IB831Z for non-tape-and-reel options or other ISL8870x variants with matching thresholds. Verify pinout compatibility and electrical parameters before substitution.
