ISL88706IP831Z

Supervisors Overview

The ISL88706IP831Z is a microprocessor supervisor circuit manufactured by Intersil, now part of Renesas. It operates within a supply voltage range of 2 V to 5.5 V and features an adjustable reset threshold voltage of 3.09 V. The device integrates a watchdog timer, power-fail comparator, manual reset input, and adjustable power-on reset functionality. It is available in PDIP-8 and SOIC-8 packages and supports an industrial operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system fault detection
• Includes a power-fail comparator for voltage monitoring
• Features a manual reset input for user-initiated control
• Provides adjustable power-on reset thresholds

Supervisors Applications

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

Supervisors Procurement Notes

Verify the manufacturer designation as Intersil or Renesas on the component marking, as corporate acquisitions may affect labeling. Confirm the suffix IP831Z corresponds to the specific 3.09V threshold and package type. Ensure compliance with RoHS standards if required by your assembly process. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog and manual reset capabilities is required. The adjustable threshold allows customization for various rail voltages within the 2V to 5.5V range. Consider the PDIP or SOIC-8 package options based on PCB layout constraints and thermal requirements. Verify that the -40°C to +85°C temperature range meets the environmental conditions of the target application.

Supervisors Part Context

This device belongs to the ISL8870x series of microprocessor supervisors, which includes models like ISL88705, ISL88707, and ISL88708. These components share similar core functionalities such as power-fail comparison and reset generation but may differ in specific threshold voltages, package types, or additional features like multiple monitor inputs. The series is designed for reliable operation in demanding electronic environments.

Supervisors Replacement Considerations

Potential substitutes include other members of the ISL8870x family, such as ISL88705, ISL88707, or ISL88708, provided their specific threshold voltages and package configurations match the design requirements. Verify pinout compatibility and functional equivalence before substitution.
