ISL88041IBZ-T

Supervisors Overview

The ISL88041IBZ-T is a multi-voltage supervisor integrated circuit manufactured by Renesas Electronics Corporation. It features four independently monitorable voltage channels with adjustable or selectable thresholds, providing flexible power management oversight. The device outputs a low-active reset signal via an open-drain or open-collector interface to ensure system integrity during undervoltage events. Designed for surface-mount installation, it utilizes an 8-SOIC package (3.90mm width) and operates reliably within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Four-channel voltage monitoring capability with configurable threshold settings
• Low-active reset output utilizing open-drain or open-collector topology
• Surface-mount construction in an 8-lead SOIC package

Supervisors Applications

• Multi-rail power supply supervision in industrial systems
• Voltage monitoring for embedded controller boards
• Power sequencing verification in telecommunications equipment

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to the obsolete status indicated in public records. Confirm package variant matches the IBZ suffix specifications. Check for RoHS compliance documentation as per current regulatory standards. Validate lot traceability if required for critical applications. Ensure storage conditions adhere to moisture sensitivity level guidelines prior to assembly.

Supervisors Selection Notes

Select this component when designing systems requiring simultaneous monitoring of multiple voltage rails without external logic. The adjustable thresholds allow customization for specific rail requirements. Consider the open-drain output compatibility with downstream logic levels. Evaluate thermal performance within the specified operating range. Verify that the 8-SOIC footprint aligns with existing PCB layout constraints.
