ISL88002IE23Z-T

Supervisors Overview

The ISL88002IE23Z-T is a voltage supervisory circuit manufactured by Renesas Electronics Corporation. It monitors a single input channel with a threshold voltage of 2.32 V and an accuracy of 1.2%. The device features an active low, open-drain output type and provides a reset delay time of 140 ms minimum. It operates within a supply voltage range of 1.8 V to 5.5 V and consumes a typical operating supply current of 350 nA. The component is housed in an SC-70-3 package and supports surface mount installation. It functions without manual reset or watchdog timer capabilities.

Supervisors Feature Summary

• Provides precise voltage supervision for single-channel power rails
• Features low quiescent current consumption for energy efficiency
• Delivers active low open-drain reset signal output

Supervisors Applications

• Industrial control systems requiring power monitoring
• Portable electronic devices needing low-power supervision
• Embedded systems utilizing simple reset/power-on reset functions

Supervisors Procurement Notes

Verify the specific suffix Z-T7A against the requested model ISL88002IE23Z-T, as datasheet records indicate the full part number includes T7A for tape-and-reel packaging. Confirm RoHS3 compliance status and moisture sensitivity level (MSL 3) requirements during handling. Check for End-of-Life notices associated with the ISL88002 series to ensure long-term availability for production planning.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with low power consumption is required. Ensure the monitored voltage aligns with the 2.32 V threshold and that the system can accommodate the 140 ms reset delay. Verify compatibility with the SC-70-3 footprint and confirm that an open-drain output interface matches the downstream logic requirements.

Supervisors Part Context

This component belongs to the ISL88002 series of voltage supervisors from Renesas Electronics. The series is designed for applications requiring reliable power management with minimal power draw. It serves as a fundamental building block for ensuring system stability by detecting under-voltage conditions and triggering appropriate reset signals.

Supervisors Replacement Considerations

Consider the ISL88002IH23Z-T for similar functionality in an SOT-23-3 package. Evaluate the ISL88002IE26Z-T if a different threshold voltage is acceptable. Verify pinout and electrical specifications before substitution.
