ISL88021IU8HFZ

Supervisors Overview

The ISL88021IU8HFZ is a triple voltage monitor supervisor manufactured by Renesas Electronics Corporation. It operates within an input voltage range of 2V to 5.5V and is housed in an 8-pin MSOP package. The device provides adjustable power-on-reset thresholds and includes undervoltage and overvoltage monitoring capabilities for up to three independent voltage inputs.

Supervisors Feature Summary

• Monitors up to three distinct voltage rails simultaneously
• Provides reset assertion when monitored voltages exceed defined limits
• Supports adjustable trip points for flexible configuration

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• Undervoltage and overvoltage protection circuits
• System reset management for microcontrollers and processors

Supervisors Procurement Notes

Verify the specific suffix 'IU8HFZ' against official Renesas documentation to confirm the exact package type, temperature grade, and tape-and-reel specifications. Ensure compatibility with your board's footprint and thermal requirements before procurement.

Supervisors Selection Notes

Select this component when simultaneous monitoring of three voltage lines is required. Consider the adjustable threshold feature if fixed-voltage supervisors do not meet specific system timing or voltage margin requirements. Verify the 8-MSOP package fits the design constraints.

Supervisors Part Context

This part belongs to the ISL88021/ISL88022 family of customizable triple voltage-monitoring supervisors. These devices are designed to assert a reset signal if any monitored voltage falls outside the acceptable range, ensuring system stability in complex electronic designs.

Supervisors Replacement Considerations

Consult official Renesas cross-reference lists for verified substitutes. Generic equivalents may lack the specific adjustable threshold characteristics or package dimensions required for direct replacement without design modification.
