ISL88011IH544Z-T7A

Supervisors Overview

The ISL88011IH544Z-T7A is a single-channel voltage supervisor manufactured by Renesas Electronics. It operates within an input voltage range of 1.2V to 5.5V and features a fixed threshold voltage of 4.45V. The device provides open-drain or push-pull reset outputs with a minimum reset timeout of 200ms. Packaged in a compact 5-pin SOT-23 (SC-74A) surface-mount format, it supports active-high or active-low logic configurations. Designed for industrial controls, it functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides precise voltage monitoring with a fixed 4.45V threshold for system integrity
• Offers flexible output configuration supporting both open-drain and push-pull modes
• Ensures stable operation through a guaranteed 200ms minimum reset timeout period

Supervisors Applications

• Industrial control systems requiring power supervision
• Embedded systems needing reliable power-on reset signals
• Portable electronics utilizing low-voltage power sources

Supervisors Procurement Notes

Verify component authenticity due to end-of-life status. Confirm package type matches SC-74A/SOT-23 specifications. Check datasheet for exact electrical tolerances. Ensure supply chain stability as availability may be limited. Validate operating temperature range requirements against industrial standards.

Supervisors Selection Notes

Select this component when a fixed 4.45V threshold is required for voltage supervision. Consider the 5-pin SOT-23 package for space-constrained designs. Evaluate the need for open-drain versus push-pull outputs based on interface requirements. Verify compatibility with the target system's voltage levels and reset timing constraints.

Supervisors Part Context

This part belongs to the ISL8801x series of voltage supervisors from Renesas. These devices are designed for simple reset and power-on reset applications. The series offers various threshold voltages and output configurations to suit different monitoring needs in portable and industrial equipment.

Supervisors Replacement Considerations

Check manufacturer documentation for direct pin-to-pin substitutes within the ISL8801x family. Verify that alternative parts match the 4.45V threshold and 200ms timeout specifications. Ensure replacement components support the same SOT-23 packaging and industrial temperature range.
