ISL88013IH531Z-TK

Supervisors Overview

The ISL88013IH531Z-TK is a single-channel voltage supervisor IC manufactured by Renesas Electronics Corporation. It operates within an ambient temperature range of -40°C to 85°C and utilizes a surface-mount SC-74A (SOT-753) package with five leads. The device features adjustable power-on reset timing, dual voltage monitoring capabilities, and watchdog timer functionality. It supports open-drain or push-pull outputs and provides high-active or low-active reset signals. The monitored voltage threshold for this specific variant is 2.92V, with a minimum reset timeout of 140ms.

Supervisors Feature Summary

• Supports adjustable power-on reset timing for flexible system initialization control
• Integrates dual voltage monitoring and watchdog timer capabilities for enhanced reliability
• Offers configurable output drivers including open-drain and push-pull options
• Provides active-high or active-low reset signal polarity selection

Supervisors Applications

• Industrial control systems requiring robust voltage supervision
• Embedded systems utilizing dual voltage monitoring for critical components
• Applications integrating watchdog timer functionality for fault recovery
• Power management circuits in industrial environments operating between -40°C and 85°C

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm package integrity as the SC-74A form factor requires precise handling. Check RoHS compliance documentation for regulatory adherence. Validate pinout compatibility with existing PCB layouts before integration. Ensure storage conditions maintain moisture sensitivity level 1 integrity.

Supervisors Selection Notes

Select this component when dual voltage monitoring and watchdog features are required in a single channel supervisor. Consider the 2.92V threshold specifically for applications targeting this voltage level. Evaluate the SOT-753 package constraints against available board space. Assess the need for adjustable reset timeouts versus fixed alternatives. Verify thermal performance requirements align with the specified operating temperature range.

Supervisors Part Context

This part belongs to the ISL88013 series of voltage supervisors from Renesas. The series offers various threshold voltages and packaging options. The IH531 suffix indicates the specific 2.92V threshold variant. The TK suffix denotes tape and reel packaging. This series is designed for industrial and commercial applications requiring reliable power management supervision.

Supervisors Replacement Considerations

ISL88013IH529Z-TK and ISL88013IH522Z-T7A are documented variants within the same family. Verify threshold voltage differences (2.92V vs 2.19V) when substituting. Confirm package compatibility between SOT-753 and alternative forms. Check reset timeout specifications for functional equivalence.
