ISL88011IH546Z-TK

Supervisors Overview

The ISL88011IH546Z-TK is a single-channel voltage supervisor integrated circuit manufactured by Renesas Electronics Corporation. It monitors one supply voltage and provides a reset signal when the monitored voltage falls below a specific threshold of 4.64V. The device supports both open-drain and push-pull output configurations, allowing for flexible interface compatibility with various microcontrollers. It features a minimum reset timeout of 200ms to ensure stable system recovery after power events. Designed for surface-mount installation in SC-74A (SOT-753) packages, it operates within an ambient temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides simple reset or power-on-reset functionality for single-channel voltage monitoring
• Supports configurable open-drain or push-pull output drivers for diverse logic interfaces
• Ensures reliable system initialization through a guaranteed minimum reset timeout period

Supervisors Applications

• Industrial control systems requiring robust power supervision
• Embedded systems needing precise voltage threshold monitoring
• Consumer electronics utilizing surface-mount power management solutions

Supervisors Procurement Notes

Verify component authenticity as this part number is officially listed as obsolete. Confirm availability through authorized distributors or secondary market suppliers. Check for updated packaging options such as tape and reel variants if standard quantities are unavailable. Ensure compliance with RoHS3 specifications during procurement. Validate that the received units match the original datasheet parameters before integration into production lines.

Supervisors Selection Notes

Select this component when a fixed 4.64V threshold is required for system supervision. Consider the open-drain or push-pull output requirements based on the target microcontroller interface. Evaluate the 200ms minimum reset timeout against system startup timing constraints. Verify that the SC-74A package fits the available PCB footprint. Compare performance against newer Renesas supervisor families if long-term supply assurance is critical for the design lifecycle.

Supervisors Part Context

This device belongs to the ISL8801x series of voltage supervisors from Renesas, which includes variants with different voltage thresholds. These components are designed to monitor power rails in embedded applications. The series offers flexibility in output configuration and reset timing. They serve as essential protection elements in power management architectures, ensuring that digital logic receives stable power before operation begins.

Supervisors Replacement Considerations

Check for direct pin-compatible replacements within the ISL8801x family that offer similar thresholds. Verify if newer Renesas supervisor ICs provide equivalent functionality with improved supply chain availability. Ensure any substitute maintains the same output drive capability and reset timeout characteristics.
