ISL88708IP829Z

Supervisors Overview

The ISL88708IP829Z is a single-channel microprocessor supervisor circuit manufactured by Intersil (Renesas). It operates within a supply voltage range of 2 V to 5.5 V, with a rated voltage of 5 V. The device features an adjustable power-on reset threshold set at 2.92 V and provides a minimum reset timeout of 140 ms. It utilizes an 8-lead Small Outline Integrated Circuit (SOIC) package with a 1.27 mm pin pitch. The component supports surface mount technology and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates manual reset functionality for system control
• Provides adjustable power-on reset thresholds
• Includes power-fail comparator capabilities

Supervisors Applications

• Microprocessor system power monitoring
• Battery function supervision in embedded systems
• Industrial control unit reset management

Supervisors Procurement Notes

Verify the specific suffix IP829Z against official Renesas documentation to confirm the exact threshold voltage and package variant. Confirm current production status as some variants in this family have been discontinued. Ensure compatibility with existing PCB footprints for the SOIC-8 package before procurement.

Supervisors Selection Notes

Select this component when a single-channel supervisor with manual reset capability is required. The adjustable threshold allows customization for specific supply rail requirements. Verify that the 140 ms minimum timeout meets the target processor's initialization timing constraints.

Supervisors Part Context

This part belongs to the ISL8870x series of microprocessor supervisors designed for high accuracy and low power consumption. The series includes variants like ISL88706 and ISL88707, sharing similar core functionalities but differing in specific thresholds and package options. These devices are engineered to monitor power-supply and battery functions in microprocessor systems.

Supervisors Replacement Considerations

Official substitutes include ISL88708IB829Z-TK and ISL88708IP831Z. Verify pinout compatibility and threshold voltage specifications before substitution.
