ISL88002IE17Z-T

Supervisors Overview

The ISL88002IE17Z-T is a low-power voltage supervisor integrated circuit manufactured by Renesas Electronics Corporation. It monitors a single input voltage channel and provides a reset signal when the supply deviates from specified thresholds. The device features an open-drain or open-collector active-low output, suitable for interfacing with various logic families. It operates within a supply voltage range of 1.8 V to 5.5 V and includes a minimum reset timeout of 140 ms. The component is housed in a compact SC-70-3 surface-mount package and supports an industrial operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Monitors a single voltage input channel for under-voltage and over-voltage conditions
• Provides an active-low reset signal via an open-drain or open-collector output interface
• Ensures system stability with a guaranteed minimum reset timeout period during power-up

Supervisors Applications

• Industrial control systems requiring reliable power supervision
• Embedded electronics needing low quiescent current monitoring
• Portable devices utilizing battery-powered architectures

Supervisors Procurement Notes

Verify the specific suffix 'T' against official Renesas documentation to confirm tape-and-reel packaging configuration. Confirm that the IE17 designation corresponds to the intended threshold voltage variant. Check current lifecycle status as some ISL88002 variants are marked obsolete. Ensure RoHS3 compliance requirements align with project specifications before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with an open-drain output is required. The SC-70-3 package offers space efficiency for dense PCB layouts. Consider the 140 ms minimum reset timeout for timing-sensitive applications. Verify that the 1.67 V threshold matches the monitored rail's critical level. Evaluate the low operating current for battery-constrained designs.
