ISL88013IH544Z-TK

Supervisors Overview

The ISL88013IH544Z-TK is a single-channel voltage supervisor integrated circuit manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2.6V to 5.5V and features a threshold voltage of 4.4V. The device provides active high and active low reset outputs with a manual reset capability. It includes a watchdog timer function and offers a minimum reset timeout of 200ms. The component is housed in a SOT-23 package and supports surface mount installation.

Supervisors Feature Summary

• Provides simultaneous active high and active low reset signals for flexible system integration
• Integrates a watchdog timer to monitor software execution integrity
• Includes manual reset functionality for controlled system recovery
• Features adjustable reset timeout duration starting from 200ms

Supervisors Applications

• Industrial control systems requiring power supervision
• Embedded microcontroller reset circuits
• Portable electronic devices with limited power budgets
• Automotive electronics monitoring applications

Supervisors Procurement Notes

Verify the specific suffix Z-TK against manufacturer documentation to confirm pinout and electrical characteristics, as suffixes often denote packaging or temperature variants. Confirm RoHS compliance status and check for End-of-Life notices, as this component may be obsolete. Ensure the selected variant matches the required threshold voltage and output configuration for the target design.

Supervisors Selection Notes

Select this component when a single-supply supervisor with both active high and low outputs is required. The integrated watchdog timer simplifies design for critical applications. Verify that the 4.4V threshold aligns with the monitored rail voltage. Consider the SOT-23 package size constraints and the -40°C to +85°C operating temperature range for environmental suitability.

Supervisors Part Context

This part belongs to the ISL88013 series of supervisory circuits from Renesas. The series typically offers various threshold voltages and output configurations to suit different power management needs. These components are designed to ensure reliable system operation by monitoring voltage levels and providing reset signals during power-up, power-down, or brown-out conditions.

Supervisors Replacement Considerations

Check for direct pin-to-pin replacements within the ISL88013 family with different thresholds. Verify compatibility with alternative supervisors offering similar watchdog and dual-output features. Ensure any substitute matches the SOT-23-5 package and electrical specifications.
