ISL88021IU8FCZ-TK

Supervisors Overview

The ISL88021IU8FCZ-TK is a triple voltage monitor supervisor from Renesas Electronics, housed in an 8-MSOP package. It provides adjustable power-on reset and undervoltage/overvoltage monitoring for three independent channels. The device features open-drain and push-pull output configurations to interface with various logic families. Designed for customizable system protection, it ensures reliable operation by detecting out-of-range supply voltages and asserting reset signals accordingly.

Supervisors Feature Summary

• Triple channel voltage monitoring with adjustable thresholds
• Adjustable power-on reset timing capability
• Supports both open-drain and push-pull output modes
• Undervoltage and overvoltage detection functions

Supervisors Applications

• Portable equipment requiring multi-rail supervision
• Industrial control systems needing voltage integrity checks
• Communication infrastructure monitoring critical power lines

Supervisors Procurement Notes

Verify the exact suffix 'TK' indicates tape-and-reel packaging when ordering. Confirm the specific threshold voltages required match the adjustable range specified in the official datasheet. Ensure the 8-MSOP footprint aligns with the target PCB design. Cross-reference the manufacturer part number to avoid confusion with similar family members like the ISL88022.

Supervisors Selection Notes

Select this component when simultaneous monitoring of three distinct voltage rails is necessary within a compact form factor. The adjustable nature of the reset and thresholds allows customization for specific system requirements. Consider the output drive capability and logic compatibility before integration into the final circuit design.

Supervisors Part Context

This part belongs to the ISL88021/ISL88022 family of customizable triple voltage-monitoring supervisors. These devices are designed to provide robust protection for electronic systems by continuously monitoring supply voltages. The family offers flexibility in setting reset times and voltage thresholds to suit diverse application needs.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the same Renesas supervisor family. Verify that any substitute supports the same triple-channel configuration and output types. Ensure electrical specifications such as operating voltage range and current consumption meet the original design constraints.
