ISL88706IB826Z-TK

Supervisors Overview

The ISL88706IB826Z-TK is a microprocessor supervisor integrated circuit manufactured by Renesas Electronics, formerly Intersil. It monitors a single power supply channel with a threshold voltage of 2.63V. The device features open-drain and push-pull outputs, providing high or low active reset signals with a minimum reset timeout of 140ms. It operates within a temperature range of -40°C to 85°C and is housed in an 8-SOIC surface-mount package.

Supervisors Feature Summary

• Integrates watchdog timer, power-fail comparator, manual reset, and adjustable power-on reset functions for comprehensive system supervision.
• Designed with high reset threshold accuracy and low power consumption to monitor power-supply and battery functions in microprocessor systems.
• Provides flexible output configurations with both open-drain and push-pull capabilities to interface with various logic families.

Supervisors Applications

• Industrial control systems requiring reliable power monitoring
• Microprocessor systems needing battery function supervision
• Embedded applications utilizing simple reset or power-on reset mechanisms

Supervisors Procurement Notes

Verify component authenticity as the ISL88706 series has been discontinued by the manufacturer. Confirm that the specific suffix IB826Z-TK matches the required tape-and-reel packaging format. Ensure compatibility with existing PCB footprints for the 8-SOIC package before finalizing procurement decisions for legacy designs.

Supervisors Selection Notes

Select this component when a single-channel supervisor with precise threshold accuracy is required for microprocessor systems. Consider the 2.63V threshold and 140ms minimum timeout against system voltage rails. Evaluate the need for combined watchdog and power-fail functionalities versus simpler reset-only devices to optimize bill of materials.

Supervisors Part Context

The ISL88706 belongs to a family of microprocessor supervisors designed for monitoring power supplies and batteries. Originally developed by Intersil, the product line was integrated into Renesas Electronics following their acquisition. These devices are engineered for industrial and commercial environments, offering robust supervision features in compact packages.

Supervisors Replacement Considerations

Public confirmed substitute part numbers include ISL88706IB826Z, ISL88706IP826Z, and ISL88706IP831Z. Verify pinout and electrical specifications match exactly before substitution.
