ISL88002IH31Z-TK

Supervisors Overview

The ISL88002IH31Z-TK is a low-power voltage supervisory circuit manufactured by Renesas Electronics Corporation (formerly Intersil). It monitors a single input voltage within a range of 1.8 V to 5.5 V. The device features an open-drain reset output and operates with a supply current of 0.35 uA. It provides specific threshold levels, including an undervoltage threshold of 3.038 V and an overvoltage threshold of 3.112 V. The component is housed in a SOT-23 package and supports an operating temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Monitors a single power supply voltage for under-voltage and over-voltage conditions
• Provides an open-drain reset signal output
• Operates with ultra-low supply current consumption

Supervisors Applications

• Low power voltage supervision in portable electronics
• Battery-powered system monitoring
• Embedded controller power management

Supervisors Procurement Notes

Verify the exact part number suffix against official Renesas documentation to confirm pinout and electrical characteristics. Ensure the sourcing channel provides genuine components with traceable manufacturing history. Check RoHS compliance status as indicated in the latest datasheet revision. Confirm packaging details match project requirements for surface mount assembly processes.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with open-drain output is required. Consider the specific undervoltage and overvoltage thresholds relative to the target supply rail. Evaluate the SOT-23 package size constraints against available PCB real estate. Verify that the operating temperature range meets the environmental conditions of the final application.

Supervisors Part Context

This part belongs to the ISL88002 series of supervisory circuits designed for low-power applications. It is part of Renesas' portfolio of power management integrated circuits, continuing the legacy of Intersil's analog and mixed-signal products. The series focuses on providing reliable voltage monitoring solutions for systems requiring minimal quiescent current.

Supervisors Replacement Considerations

Consult official Renesas documentation for confirmed substitute part numbers. Cross-reference specifications such as threshold voltages, package type, and output configuration before considering alternatives.
