ISL88002IE31Z-TK

Supervisors Overview

The ISL88002IE31Z-TK is a voltage supervisory circuit manufactured by Renesas Electronics Corporation. It monitors a single input with an undervoltage threshold of 3.038 V and an overvoltage threshold of 3.112 V. The device operates within a supply voltage range of 1.8 V to 5.5 V and features an active-low open-drain reset output. It consumes a maximum operating supply current of 0.35 uA. The component is housed in an SOT-23 package and supports an operating temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Provides voltage supervision for a single monitored input channel
• Features an active-low open-drain reset output signal
• Designed for low-power applications with minimal operating supply current

Supervisors Applications

• Low power voltage supervision systems
• Embedded electronic circuits requiring voltage monitoring
• Portable devices with limited power budgets

Supervisors Procurement Notes

Verify the specific suffix 'IE31' against official Renesas documentation to confirm the exact threshold voltage configuration, as suffixes often denote precise parameter variations. Ensure the sourcing channel provides valid RoHS compliance data and confirms the component status, as availability may vary due to lifecycle changes. Cross-reference the part number with authorized distributors to ensure authenticity and traceability before procurement.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with an open-drain output is required for low-power designs. The wide supply voltage range accommodates various logic levels. Consider the specific threshold values relative to the monitored rail to ensure proper reset triggering. Verify that the SOT-23 package fits the board space constraints and that the operating temperature range meets the environmental requirements of the target application.

Supervisors Part Context

This part belongs to the ISL88002 series of supervisory circuits from Renesas (formerly Intersil). The series offers various threshold options packaged in small form factors like SOT-23 and SC-70. These components are designed for power management tasks where monitoring voltage integrity is critical for system stability and protection against abnormal power conditions.

Supervisors Replacement Considerations

Check for direct substitutes within the ISL88002 family that match the 3.1 V threshold and SOT-23 package. Verify pin compatibility and electrical specifications before replacing. Consult Renesas documentation for any recommended upgrades or end-of-life notices affecting this specific part number.
