ISL88001IH22Z-T7A

Supervisors Overview

The ISL88001IH22Z-T7A is a single-channel voltage monitoring supervisor manufactured by Renesas Electronics. It operates within an input voltage range of 1.6V to 5.5V and features a fixed threshold of 2.19V for precise power supply monitoring. The device provides an active-low reset output with a minimum timeout of 140ms, ensuring reliable system recovery during brown-out events. Packaged in a compact SC-70-3 surface-mount format, it supports industrial temperature ranges from -40°C to +85°C.

Supervisors Feature Summary

• Provides precise monitoring of power supply voltages through a fixed threshold configuration
• Generates a reset signal with a guaranteed minimum timeout duration for system stability
• Utilizes a low-profile surface-mount package suitable for space-constrained designs

Supervisors Applications

• Industrial control systems requiring voltage supervision
• Portable electronic devices needing efficient power management
• Embedded systems utilizing microcontrollers or processors

Supervisors Procurement Notes

Verify component authenticity through authorized distributors. Confirm the specific suffix matches the required threshold voltage. Check for obsolescence notices as this series may have limited availability. Ensure compliance with RoHS3 standards for environmental regulations. Validate packaging details against current manufacturing data sheets before ordering.

Supervisors Selection Notes

Select this component when a fixed 2.19V threshold is required for system supervision. Consider the SC-70-3 package size for board layout constraints. Evaluate the active-low reset polarity against downstream logic requirements. Compare performance against other ISL8800x variants if different thresholds are needed.

Supervisors Part Context

This part belongs to the ISL88001 family of single voltage monitoring supervisors. It is designed for applications requiring simple reset generation without external components. The series offers various fixed voltage options to accommodate different standard power rails in electronic circuits.

Supervisors Replacement Considerations

Direct substitutes include other ISL88001 variants with identical packages but different threshold voltages, such as ISL88001IE31Z-T7A for 3.075V monitoring. Verify pin compatibility and reset polarity before substitution.
