ISL6536AIBZ

Supervisors Overview

The ISL6536AIBZ is a four-channel voltage supervisory circuit manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2.7 V to 4 V and features programmable threshold voltages for monitoring multiple power rails. The device provides active low reset signals via an open-drain or open-collector output configuration, ensuring compatibility with various logic families. Designed for surface-mount installation in an 8-SOIC package, it supports industrial operating temperatures from -40°C to +85°C. This component integrates multi-voltage supervision capabilities without requiring external manual reset inputs or watchdog timers.

Supervisors Feature Summary

• Monitors four independent voltage inputs simultaneously
• Features adjustable threshold voltage settings
• Provides active low reset signal output
• Supports open-drain or open-collector output topology

Supervisors Applications

• Multi-rail power system supervision
• Industrial equipment voltage monitoring
• Embedded system power integrity verification

Supervisors Procurement Notes

Verify component authenticity through authorized distributors as the part is obsolete. Confirm RoHS compliance status, as the 'A' suffix typically indicates lead-free packaging compared to standard versions. Check for parameter-equivalent replacements like the ISL88041IBZ if current stock is unavailable. Ensure the 8-SOIC package dimensions match your PCB footprint requirements before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage levels is required. The programmable thresholds allow customization for specific rail tolerances. Verify that the active low reset polarity aligns with the target microcontroller or FPGA input requirements. Consider the open-drain output capability for level shifting applications. Ensure the operating temperature range meets the environmental conditions of the intended deployment scenario.

Supervisors Part Context

The ISL6536AIBZ belongs to the ISL6536 series of supervisory circuits from Renesas Electronics. It serves as a specialized power management integrated circuit designed for reliability in complex electronic systems. The 'A' designation typically denotes enhanced environmental compliance, such as RoHS adherence. This part represents a legacy solution for multi-voltage supervision tasks in established industrial and commercial hardware designs.

Supervisors Replacement Considerations

The ISL88041IBZ is documented as a parameter-equivalent replacement for the ISL6536AIBZ. Verify pinout compatibility and electrical specifications before substitution. Both components share similar four-channel supervision functions and 8-SOIC packaging formats.
