ISL88011IH546Z-T7A

Supervisors Overview

The ISL88011IH546Z-T7A is a single-channel voltage supervisor integrated circuit manufactured by Renesas Electronics Corporation. It operates within a supply voltage range up to 5.5 V and features a fixed threshold of 4.64 V for power monitoring. The device provides open-drain and push-pull output configurations with selectable active-high or active-low reset signals. It includes a minimum reset timeout of 200 ms to ensure system stability during power transitions. Designed for surface-mount installation in a 5-SOT (SC-74A) package, it supports an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides dual-output capability with both open-drain and push-pull reset signal options for flexible interface compatibility.
• Features a manual reset input pin allowing external control over the system reset state independent of voltage monitoring.
• Includes a watchdog timer function to detect software malfunctions and trigger a system reset if not serviced periodically.

Supervisors Applications

• Industrial control systems requiring reliable power supervision
• Embedded systems needing manual reset functionality
• Applications utilizing watchdog timer protection

Supervisors Procurement Notes

Verify component authenticity through authorized distributors as this part may be subject to obsolescence notices. Confirm package markings and datasheet revisions match the specific batch requirements. Check for RoHS compliance status and moisture sensitivity level handling instructions prior to assembly. Ensure design-in documentation aligns with current Renesas product lifecycle announcements.

Supervisors Selection Notes

Select this component when a single monitored voltage channel with both open-drain and push-pull outputs is required. The 4.64 V threshold suits applications monitoring standard 5 V logic supplies. Consider the manual reset input and watchdog features if system robustness against software faults is critical. Verify that the SC-74A package fits the PCB layout constraints.

Supervisors Part Context

This supervisor belongs to the ISL8801x series, which offers various threshold voltages and feature combinations. The ISL88011 specifically targets applications needing simple reset generation with additional manual control. It complements other Renesas PMIC solutions by providing dedicated voltage monitoring without complex configuration interfaces.

Supervisors Replacement Considerations

Check for direct substitutes within the ISL8801x family with different thresholds. Verify pinout compatibility before replacing. Consult Renesas for end-of-life alternatives if production continuity is required.
