ISL88708IB829Z-TK

Supervisors Overview

The ISL88708IB829Z-TK is a microprocessor supervisory circuit manufactured by Renesas Electronics Corporation. It monitors a single voltage channel with a threshold of 2.92V. The device features open-drain and push-pull outputs, supporting both high-active and low-active reset configurations. It provides a minimum reset timeout of 140ms. Operating within a temperature range of -40°C to 85°C, it is housed in an 8-SOIC package (3.90mm width) and utilizes tape-and-reel packaging.

Supervisors Feature Summary

• Provides simple reset and power-on reset functionality for monitored voltage channels.
• Offers flexible output configuration with open-drain and push-pull options.
• Supports configurable active-high or active-low reset signal polarity.

Supervisors Applications

• Industrial control systems requiring voltage supervision
• Embedded systems needing reliable power-on reset mechanisms
• Microprocessor monitoring circuits

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to discontinued status. Confirm specific suffix requirements for tape-and-reel packaging. Check current availability as the product may be obsolete. Ensure compatibility with existing board designs regarding the 8-SOIC footprint and electrical specifications before procurement.

Supervisors Selection Notes

Select this component when a single-channel supervisor with adjustable reset polarity is required. Consider the 2.92V threshold against system voltage rails. Evaluate the 140ms minimum timeout against processor startup times. Verify that the 8-SOIC package fits the available PCB space and thermal constraints.

Supervisors Part Context

This part belongs to the ISL88708 family of supervisory circuits from Renesas. It shares functional similarities with variants like ISL88708IB826Z but differs in threshold voltage and packaging format. The family is designed for general-purpose voltage monitoring in industrial and commercial applications.

Supervisors Replacement Considerations

Public confirmed substitute part numbers include ISL88708IB826Z and ISL88708IB831Z. Verify threshold voltage differences and packaging compatibility before substitution.
