ISL88001IH26Z-TK

Supervisors Overview

The ISL88001IH26Z-TK is a voltage supervisory circuit manufactured by Renesas Electronics Corporation. It monitors a single input voltage with a threshold of 2.63 V and an overvoltage threshold of 2.662 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 accuracy of 1.2%. The component functions at a quiescent current of 350 nA and is housed in an SOT-23-3 package.

Supervisors Feature Summary

• Monitors a single power rail for under-voltage and over-voltage conditions
• Provides an active low open-drain reset signal upon fault detection
• Operates with ultra-low quiescent current for efficient power management

Supervisors Applications

• Portable electronic devices requiring battery voltage monitoring
• Embedded systems needing reliable power-on reset sequences
• Industrial control circuits ensuring stable logic operation

Supervisors Procurement Notes

Verify the specific suffix Z-TK against official Renesas documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Check for end-of-life notices or production change notifications that may affect availability or pin compatibility. Ensure the supplier provides valid traceability documents for quality assurance purposes.

Supervisors Selection Notes

Select this component when a single-channel supervisor with open-drain output is required. The 2.63 V threshold suits applications monitoring 3.3 V or similar logic rails. Consider the 190 ms delay for system startup timing requirements. Verify that the open-drain output can interface correctly with the target microcontroller's input voltage levels without external pull-up conflicts.

Supervisors Part Context

This part belongs to the ISL88001 series of voltage supervisors from Renesas. These components are designed for simple, cost-effective power management tasks. The series typically offers various threshold voltages and package options to accommodate different design constraints. It serves as a fundamental building block for ensuring system stability during power transitions.

Supervisors Replacement Considerations

Check for direct cross-reference part numbers from Renesas or other manufacturers offering identical 2.63 V thresholds and SOT-23-3 packages. Verify pinout compatibility and electrical characteristics such as reset delay and quiescent current before substitution.
