ISL6536IBZ

Supervisors Overview

The ISL6536IBZ is a voltage supervisory circuit manufactured by Renesas Electronics Corporation, designed for monitoring multiple power rails. It features four independent input channels to track system voltages simultaneously. The device utilizes an 8-pin SOIC surface-mount package, suitable for compact PCB layouts. It operates within a supply voltage range of 2.7 V to 4 V and supports an industrial temperature range from -40°C to +85°C. The output configuration consists of active high signals with open-drain capability, allowing flexible interfacing with various logic families without requiring manual reset or watchdog timer functions.

Supervisors Feature Summary

• Four-channel voltage supervision for simultaneous multi-rail monitoring
• Active high open-drain output interface for logic compatibility
• Industrial temperature rating for robust environmental operation

Supervisors Applications

• Multi-voltage power supply monitoring in industrial systems
• System integrity verification in embedded controllers
• Voltage threshold detection in communication equipment

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance details as specified in the official datasheet, noting potential regulatory variations. Check for parameter-equivalent replacements like the ISL88041IBZ if current stock is unavailable. Ensure packaging specifications match design requirements, as legacy components may have specific handling constraints. Validate operating temperature ranges against application thermal profiles before integration.

Supervisors Selection Notes

Select this component when four distinct voltage rails require simultaneous supervision within a low-profile 8-SOIC footprint. The active high open-drain outputs simplify interface design compared to active low alternatives. Consider the 2.7 V minimum supply requirement to ensure proper operation across the intended voltage range. The absence of manual reset and watchdog features reduces pin count but requires external circuitry if those functions are needed. Verify that the programmable threshold capabilities align with the specific voltage levels being monitored.

Supervisors Part Context

The ISL6536 belongs to the ISL6536 series of supervisory circuits from Renesas/Intersil. It is part of the broader PMIC category, specifically focusing on voltage monitoring rather than regulation. This family targets applications requiring reliable power sequence verification and fault detection. The component represents Intersil's legacy portfolio now managed under Renesas Electronics, maintaining compatibility with established designs while offering modern reliability standards.

Supervisors Replacement Considerations

The ISL88041IBZ is identified as a parameter-equivalent replacement. Verify pinout compatibility and electrical characteristics before substitution. Ensure the replacement maintains the four-channel supervision requirement and open-drain output structure.
