ISL88011IH523Z-T7A

Supervisors Overview

The ISL88011IH523Z-T7A is a single-channel voltage supervisor IC manufactured by Renesas Electronics Corporation. It monitors one input voltage and provides reset signals with active high and active low outputs. The device features a manual reset capability and includes an integrated watchdog timer for system reliability. It operates within a supply voltage range up to 5.5 V and maintains accuracy of 1.5%. The component supports surface mount installation in a SOT-23 package and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides dual polarity reset outputs (active high and active low) for flexible logic interfacing
• Integrates a watchdog timer to detect software or hardware malfunctions
• Supports manual reset functionality via external push-button input
• Delivers precise voltage supervision with specified threshold accuracy

Supervisors Applications

• Industrial control systems requiring power monitoring
• Embedded systems needing reliable reset management
• Consumer electronics utilizing single-rail power architectures
• Automotive modules demanding robust supervisory circuits

Supervisors Procurement Notes

Verify component authenticity through authorized distributors as the part status indicates end-of-life conditions. Confirm RoHS compliance and specific suffix designations match application requirements. Check for obsolescence notices and lead time constraints due to limited availability. Ensure packaging format aligns with automated assembly processes.

Supervisors Selection Notes

Select this supervisor when a single monitored rail requires both high and low active reset signals. Consider the integrated watchdog feature if software stability monitoring is necessary. Evaluate the 2.63 V threshold against the target system voltage to ensure proper triggering. Assess the SOT-23 package size against board space limitations.

Supervisors Part Context

This component belongs to the ISL8801x series of voltage supervisors from Renesas, designed for simple reset and power-on reset applications. It complements other parts in the family like the ISL88013 and ISL88015, offering similar functional blocks but differentiated by specific voltage thresholds and output configurations suitable for various industrial and commercial environments.

Supervisors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the end-of-life status, direct replacements may require redesigning the circuit for compatible supervisors with matching thresholds and packages.
