ISL88001IE17Z-T7A

Supervisors Overview

The ISL88001IE17Z-T7A is a single-channel voltage supervisor IC manufactured by Renesas Electronics Corporation. It operates within an ambient temperature range of -40°C to 85°C and utilizes a surface-mount SC-70 (SOT-323) package with three terminals. The device features a fixed voltage threshold of 1.67V for monitoring a single input channel. It provides a simple reset or power-on reset function with a minimum reset timeout of 140ms. The output configuration is push-pull/totem pole, generating a low-active reset signal. The component is classified as a PMIC supervisory circuit.

Supervisors Feature Summary

• Provides active-low reset signaling via a push-pull output interface
• Monitors a single voltage input channel against a fixed threshold
• Ensures system stability through a defined minimum reset timeout period

Supervisors Applications

• Industrial control systems requiring voltage supervision
• Embedded electronics needing power-on reset functionality
• Portable devices utilizing low-voltage power rails

Supervisors Procurement Notes

Verify the specific suffix 'T7A' to confirm the SC-70-3 packaging and tape-and-reel delivery format. Confirm that the 1.67V threshold aligns with the target supply rail requirements. Check current lifecycle status as this part may be subject to discontinuation notices. Ensure compatibility with existing PCB footprints for SOT-323 packages during procurement planning.

Supervisors Selection Notes

Select this component when a low-cost, single-channel supervisor with a push-pull output is required. The 1.67V threshold suits applications monitoring lower voltage rails. Consider the SC-70 package size for space-constrained designs. Verify that the 140ms timeout meets the system's startup timing constraints compared to alternatives with longer delays.

Supervisors Part Context

This part belongs to the ISL88001 series of voltage supervisors from Renesas. It shares the same package and general functionality as variants like the ISL88002 and ISL88003 but differs in output type and threshold. The series is designed for industrial and consumer applications requiring reliable power management. The T7A suffix indicates the specific reel packaging configuration.

Supervisors FAQ

What is the logic level of the reset output?

The reset output is active-low, meaning it asserts a low signal when a fault is detected.

Does this IC include a manual reset pin?

No, the ISL88001IE17Z-T7A does not feature a manual reset input; it relies on automatic power-on and undervoltage detection.
