ISL88813IB846Z

Supervisors Overview

The ISL88813IB846Z is a single-channel microprocessor supervisor manufactured by Renesas Electronics Corporation. It operates within a voltage range of 5V to 5V and features a reset threshold of 4.38V. The device provides a minimum reset timeout of 140ms and supports both open-drain and push-pull/totem pole output configurations. It offers selectable active-high or active-low reset signals for simple reset or power-on reset applications. The component is housed in an 8-SOIC package with a width of 3.90mm and is designed for surface mount installation.

Supervisors Feature Summary

• Supports configurable push-pull or open-drain output stages
• Provides selectable active-high or active-low reset polarity
• Integrates watchdog timer functionality alongside power monitoring

Supervisors Applications

• Industrial control systems requiring reliable power supervision
• Embedded systems utilizing microprocessors needing reset management
• General-purpose electronic circuits requiring power-on reset generation

Supervisors Procurement Notes

Verify the obsolete lifecycle status before procurement planning. Confirm that the 8-SOIC package dimensions match the design footprint. Ensure compatibility with the 5V operating voltage and 4.38V threshold requirements. Check for RoHS3 compliance if environmental regulations apply. Validate that the specific suffix IB846Z matches the required output configuration and pinout.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog capabilities is required. It is suitable for designs needing flexible reset output types and polarities. Consider the 140ms minimum timeout for system stability requirements. Evaluate the 8-SOIC package constraints against available board space. Verify that the fixed 4.38V threshold aligns with the monitored rail voltage.
