ISL88002IH46Z-T7A

Supervisors Overview

The ISL88002IH46Z-T7A is a single-channel voltage supervisor IC manufactured by Renesas Electronics. It monitors one input voltage against a fixed threshold of 4.62V. The device features an open-drain output that asserts low when the monitored voltage falls below the threshold. It includes a reset delay time of 190ms to ensure stable operation during power transitions. The component operates within a temperature range of -40°C to 85°C and is housed in a compact SOT-23-3 surface-mount package.

Supervisors Feature Summary

• Provides simple reset or power-on reset functionality for single voltage rails
• Utilizes an open-drain output configuration for flexible interfacing
• Ensures reliable system recovery with a defined reset delay timer

Supervisors Applications

• Industrial control systems requiring voltage monitoring
• Embedded systems needing power-on reset generation
• Portable electronic devices with limited board space

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance and MSL rating before integration. Check for updated datasheet revisions referenced in recent product change notices. Ensure supply chain stability as inventory may be limited after production discontinuation.

Supervisors Selection Notes

Select this part when a fixed 4.62V threshold is required for single-supervision applications. The SOT-23-3 package suits space-constrained designs. Consider the open-drain output compatibility with system logic levels. Evaluate the 190ms reset delay against system startup timing requirements.
