ISL88706IB829Z-TK

Supervisors Overview

The ISL88706IB829Z-TK is a microprocessor supervisor IC manufactured by Renesas Electronics Corporation, designed to monitor power-supply and battery functions in microprocessor systems. It features a single monitored channel with a threshold voltage of 2.92V. The device provides open-drain and push-pull outputs, supporting both high-active and low-active reset configurations. It includes a watchdog timer, power-fail comparator, manual reset capability, and adjustable power-on reset. The minimum reset timeout is 140ms. 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 a watchdog timer for system stability monitoring
• Includes a power-fail comparator for voltage supervision
• Supports manual reset functionality alongside automatic power-on reset
• Offers configurable active-high or active-low reset output polarity

Supervisors Applications

• Microprocessor system power supply monitoring
• Battery function supervision in embedded devices
• Industrial control system reset management

Supervisors Procurement Notes

Verify component authenticity through authorized distributors as the part status is listed as obsolete. Confirm that the specific suffix corresponds to the tape-and-reel packaging variant rather than tube packaging. Ensure compatibility with existing design specifications regarding the 2.92V threshold and 8-SOIC footprint before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a combined solution for power supervision and watchdog timing is required in a compact surface-mount package. The dual-output configuration allows flexibility in interfacing with different logic families. Consider the fixed 2.92V threshold suitability for the target rail voltage and verify that the -40°C to 85°C operating range meets environmental requirements.

Supervisors Part Context

This device belongs to the ISL8870x series of microprocessor supervisors from Renesas, which are designed for high accuracy and low power consumption. The series monitors power supplies and batteries in microprocessor applications. The ISL88706 specifically adds watchdog and power-fail capabilities compared to simpler reset generators, providing comprehensive system protection in an 8-pin form factor.
