ISL88002IH23Z-TK

Supervisors Overview

The ISL88002IH23Z-TK is a voltage supervisory circuit manufactured by Renesas Electronics Corporation, designed for low-power applications. It features an open-drain active-low reset output and monitors a single input channel with a threshold voltage of 2.32 V. The device operates within a supply voltage range of 1.8 V to 5.5 V and consumes a typical operating current of 350 nA. It provides a reset delay time of 190 ms and maintains an accuracy of 1.2%. The component is housed in a SOT-23-3 package and supports surface mount installation. It functions without manual reset or watchdog timer capabilities.

Supervisors Feature Summary

• Provides low-power voltage supervision with an open-drain active-low reset output for reliable system monitoring.
• Features high accuracy of 1.2% with a fixed threshold voltage of 2.32 V for precise power management.
• Operates efficiently with ultra-low quiescent current consumption suitable for battery-powered designs.

Supervisors Applications

• Industrial control systems requiring voltage supervision
• Portable electronic devices needing low-power monitoring
• Embedded systems utilizing single-channel voltage tracking

Supervisors Procurement Notes

Verify the specific suffix Z-TK against official Renesas documentation to confirm packaging and tape-and-reel specifications. Confirm end-of-life status as multiple sources indicate obsolescence. Ensure RoHS compliance matches current regulatory requirements. Validate that the SOT-23-3 package aligns with your PCB footprint constraints before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a simple, low-cost supervisor with a fixed 2.32 V threshold is required. It is suitable for designs where manual reset and watchdog functions are unnecessary. Consider the 190 ms reset delay and 1.2% accuracy for timing-sensitive applications. Ensure the 5.5 V maximum supply voltage meets your system's rail requirements.

Supervisors Part Context

This part belongs to the ISL88002 series of voltage supervisors from Renesas (formerly Intersil). The series offers various threshold voltages and packages. The IH23 variant specifically targets the 2.32 V threshold application. It is categorized under PMIC - Power Management ICs and Supervisory Circuits, serving as a fundamental building block for power integrity in mixed-signal systems.

Supervisors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided data. Check for ISL88002 variants with different thresholds or packages if exact replacement is unavailable due to end-of-life status.
