ISL88706IB826Z

Supervisors Overview

The ISL88706IB826Z is a microprocessor supervisor integrated circuit manufactured by Renesas Electronics (formerly Intersil). It operates within a supply voltage range of 2 V to 5.5 V and features an adjustable power-on reset threshold set at 3.09 V. The device provides manual reset functionality, a watchdog timer, and a power-fail comparator. It supports active-high or active-low reset outputs with open-drain or push-pull configurations. The component is housed in an 8-SOIC surface-mount package and is rated for industrial operating temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Integrates watchdog timer, power-fail comparator, and manual reset capabilities for comprehensive system monitoring
• Features adjustable power-on reset threshold allowing customization of the reset trigger voltage
• Offers flexible output drive options including open-drain and push-pull configurations for compatibility with various logic levels

Supervisors Applications

Supervisors Procurement Notes

Verify current availability status as this component may be discontinued or subject to production changes. Confirm that the specific suffix IB826Z matches the required pinout and electrical characteristics for your design. Check for official product change notices regarding manufacturing site transfers or labeling updates before finalizing procurement plans.

Supervisors Selection Notes

Select this component when an adjustable reset threshold near 3.09 V is required alongside integrated watchdog and power-fail functions. Ensure the 8-SOIC package fits the board layout constraints. Verify that the operating temperature range of -40°C to +85°C meets the environmental requirements of the target application.

Supervisors Part Context

This part belongs to the ISL8870x family of microprocessor supervisors designed for high accuracy and low power consumption. The series includes variants like the ISL88705, ISL88707, and ISL88708, which share similar functional blocks but differ in reset thresholds and specific feature sets. The ISL88706 specifically targets applications needing precise voltage monitoring with configurable reset timing.

Supervisors Replacement Considerations

Direct substitutes within the same family include ISL88705, ISL88707, and ISL88708. When replacing, verify that the reset threshold voltage and output configuration of the substitute part match the original design requirements.
