ISL88002IH26Z-TK

Supervisors Overview

The ISL88002IH26Z-TK is a voltage supervisory circuit manufactured by Renesas Electronics Corporation. It monitors a single input channel with a threshold voltage of 2.63 V. The device features an active low, open-drain reset output and operates within a supply voltage range of 1.8 V to 5.5 V. It provides a reset delay time of 190 ms and maintains an operating supply current of 350 nA. The component supports undervoltage detection at 3.038 V and overvoltage detection at 2.662 V. It functions reliably across a temperature range of -40°C to +85°C and is housed in a SOT-23-3 package.

Supervisors Feature Summary

• Monitors a single voltage input channel for power supply integrity
• Provides an active low reset signal via an open-drain output configuration
• Detects both undervoltage and overvoltage conditions relative to the set threshold

Supervisors Applications

• Low power voltage supervision in embedded systems
• Monitoring critical rails in industrial control applications
• Power management circuits requiring precise threshold detection

Supervisors Procurement Notes

Verify the specific suffix Z-TK against the manufacturer's latest documentation to confirm packaging and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for any product change notices regarding label updates or end-of-life status before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 2.63 V threshold is required for single-channel monitoring. Ensure the open-drain output capability matches the pull-up requirements of the connected microcontroller or logic interface. Verify that the 350 nA supply current meets the system's standby power constraints and that the SOT-23-3 package fits the available board space.

Supervisors Part Context

This part belongs to the ISL88002 series of supervisory circuits from Renesas. The series offers various threshold voltages and packages to suit different power monitoring needs. The IH26 variant specifically targets applications requiring a 2.63 V trip point. It serves as a fundamental building block for ensuring system stability during power-up and power-down sequences.

Supervisors Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the ISL88002 family that offer different threshold voltages if the 2.63 V setting is not suitable. Verify that any substitute maintains the same open-drain output type and operating temperature range.
