ISL88011IH531Z-TK

Supervisors Overview

The ISL88011IH531Z-TK is a single-channel voltage supervisor IC manufactured by Renesas Electronics Corporation. It monitors one input voltage with a threshold of 3.1V and provides an open-drain or push-pull reset output. The device operates within a supply voltage range of 1.8V to 5.5V, featuring a minimum reset timeout of 200ms. It supports active-high or active-low reset configurations and functions across a temperature range of -40°C to +85°C in a 5-SOT package.

Supervisors Feature Summary

• Monitors a single power supply rail for undervoltage conditions
• Configurable reset output polarity for system flexibility
• Provides defined reset timeout duration for stable startup

Supervisors Applications

• Industrial control systems requiring power supervision
• Embedded applications needing simple reset generation
• Portable devices utilizing low-voltage operation

Supervisors Procurement Notes

Verify component authenticity through authorized distributors. Confirm the specific suffix matches the required threshold and output configuration. Check current availability status as this part may be subject to end-of-life notices. Ensure storage conditions comply with moisture sensitivity level requirements before assembly.

Supervisors Selection Notes

Select this component when a single voltage channel monitoring solution is sufficient. Consider the fixed threshold voltage against system requirements. Evaluate the package size constraints for surface mount implementation. Verify compatibility with the target operating temperature range for the intended application environment.

Supervisors Part Context

This supervisor belongs to the ISL8801x series designed for basic power management tasks. It complements more complex multi-channel supervisors like the ISL88031. The series focuses on cost-effective solutions for essential reset generation without additional features like watchdog timers or manual resets.

Supervisors Replacement Considerations

ISL88011IH546Z-T7A offers a similar function with a different threshold voltage.
