ISL88002IE26Z-TK

Supervisors Overview

The ISL88002IE26Z-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 and an overvoltage threshold of 2.662 V. The device features an active low, open-drain reset output and provides a reset delay time of 190 ms. It operates within a supply voltage range of 1.8 V to 5.5 V, consuming a typical quiescent current of 350 nA. Accuracy is specified at 1.2%. The component is housed in an SOT-23-3 surface-mount package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Monitors a single voltage input channel for under-voltage and over-voltage conditions
• Provides an active low reset signal via an open-drain output configuration
• Ensures system stability with a fixed reset delay time of 190 ms
• Designed for low-power applications with minimal quiescent current consumption

Supervisors Applications

• Low power voltage supervision in portable electronic devices
• Monitoring battery-powered systems requiring precise threshold detection
• Industrial control circuits needing reliable power management supervision

Supervisors Procurement Notes

Verify the specific suffix 'TK' against official Renesas documentation to confirm packaging details and availability status. Confirm that the SOT-23-3 package matches design requirements. Check for any product change notices regarding label updates or end-of-life status. Ensure compliance with RoHS3 specifications for environmental regulations. Validate operating temperature ranges against application constraints.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with open-drain output is required. Consider the 2.63 V threshold for applications monitoring 2.5 V or similar nominal rails. Evaluate the 190 ms reset delay against system startup timing requirements. Assess the 350 nA quiescent current impact on overall system power budget. Verify compatibility with the SOT-23-3 footprint during PCB layout.
