ISL88708IB831Z

Supervisors Overview

The ISL88708IB831Z is a microprocessor supervisor manufactured by Renesas Electronics Corporation, designed to monitor power-supply and battery functions in microprocessor systems. It features a single channel with an adjustable power-on reset threshold of 3.09V. The device provides manual reset capability and operates within a supply voltage range of 2V to 5.5V. It utilizes an 8-SOIC surface-mount package and supports both open-drain and push-pull outputs. The component ensures system reliability through high reset threshold accuracy and low power consumption.

Supervisors Feature Summary

• Provides manual reset functionality for system control
• Features adjustable power-on reset threshold for flexible monitoring
• Supports open-drain and push-pull output configurations

Supervisors Applications

• Industrial controls
• Microprocessor system power monitoring
• Battery function supervision

Supervisors Procurement Notes

Verify the specific suffix IB831Z against official Renesas documentation to confirm the exact threshold voltage and output configuration, as variations exist within the ISL88708 family. Confirm RoHS compliance status and check for any product change notices or obsolescence announcements prior to procurement, as availability may be limited.

Supervisors Selection Notes

Select this component when a single-channel supervisor with manual reset and adjustable thresholds is required. Ensure the operating temperature range of -40°C to 85°C meets application requirements. Verify that the 8-SOIC package dimensions are compatible with the PCB layout and that the 2V to 5.5V supply range aligns with the target system voltage.

Supervisors Part Context

The ISL88708 belongs to a family of microprocessor supervisors including the ISL88705, ISL88706, ISL88707, ISL88716, and ISL88813. These devices share common design goals of high reset threshold accuracy and low power consumption. The ISL88708 specifically offers manual reset and adjustable power-on reset features, distinguishing it from simpler variants within the same series.

Supervisors Replacement Considerations

Potential substitutes include other models within the ISL88708 family such as ISL88708IB826Z or ISL88708IP831Z, provided their specific threshold voltages and package types match the design requirements.
