ISL88002IH44Z-T7A

Supervisors Overview

The ISL88002IH44Z-T7A is a single-channel voltage supervisor integrated circuit manufactured by Renesas Electronics Corporation. It monitors one input voltage with a threshold of 4.43V and an overvoltage threshold of 4.433V. The device features an open-drain or open-collector output type and provides a low-active reset signal. It operates within a supply voltage range up to 5.5V and consumes a maximum operating supply current of 400 nA. The component is housed in a SC-70 (SOT-23-3) surface-mount package and supports manual reset functionality.

Supervisors Feature Summary

• Provides precise monitoring of a single power rail with dedicated overvoltage detection capabilities.
• Features an open-drain/reset output compatible with various logic families for flexible system integration.
• Includes manual reset capability allowing external control over the reset state generation.

Supervisors Applications

• Industrial control systems requiring reliable power supervision
• Embedded electronics needing single-rail voltage monitoring
• Portable devices utilizing low-power supervisor circuits

Supervisors Procurement Notes

Verify component authenticity through authorized distributors as this part may be obsolete. Confirm package integrity and pin alignment against the SC-70/SOT-23-3 specification. Check RoHS compliance status and moisture sensitivity level handling requirements prior to assembly. Ensure the specific suffix matches the required threshold voltage variant.

Supervisors Selection Notes

Select this component when a single-channel supervisor with high accuracy is required for voltages near 4.4V. Consider the open-drain output configuration for compatibility with different logic levels. Evaluate the low quiescent current for battery-operated applications. Verify that the SC-70 package fits the available PCB footprint constraints.
