ISL88708IB829Z

Supervisors Overview

The ISL88708IB829Z is a microprocessor supervisor integrated circuit manufactured by Renesas Electronics Corporation. It monitors a single voltage channel with a threshold of 2.92V and provides open-drain or push-pull outputs for reset signaling. The device supports high-active or low-active reset configurations and features a minimum reset timeout of 140ms. Designed for surface-mount installation in an 8-SOIC package, it operates within a temperature range of -40°C to 85°C.

Supervisors Feature Summary

• Provides simple reset and power-on reset functionality for monitored voltage channels
• Supports configurable active-high or active-low reset output polarity
• Offers dual-output capability with selectable open-drain or push-pull drive modes

Supervisors Applications

• Industrial control systems requiring voltage supervision
• Embedded systems needing reliable power-fail detection
• Microprocessor reset circuits in consumer electronics

Supervisors Procurement Notes

Verify component status as the ISL88708 series has been officially discontinued. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing design specifications before procurement. Check for alternative manufacturing site notices or product change notifications that may affect sourcing decisions.

Supervisors Selection Notes

Select this component when a single-channel supervisor with adjustable threshold is required. The 2.92V threshold suits applications monitoring specific voltage rails. Consider the 8-SOIC package for space-constrained designs. Verify that the 140ms minimum timeout meets system startup requirements. Evaluate the open-drain or push-pull output options based on interface needs.

Supervisors Part Context

The ISL88708IB829Z belongs to the ISL88708 family of microprocessor supervisors from Renesas. This series includes variants with different thresholds and packaging options. The IB suffix indicates an 8-SOIC package. The part is designed for industrial and commercial applications requiring robust voltage monitoring and reset generation capabilities.

Supervisors Replacement Considerations

Publicly confirmed substitute part numbers include ISL88708IB826Z, ISL88708IB831Z, and ISL88708IP844Z. These alternatives share similar functionality but may differ in threshold voltage or package type. Verify electrical parameters and pin compatibility before substitution.
