ISL88002IE23Z-TK

Supervisors Overview

The ISL88002IE23Z-TK is a voltage supervisory circuit manufactured by Renesas Electronics Corporation. It monitors a single input channel with a threshold voltage of 2.32 V and an overvoltage threshold of 2.348 V. The device features an active low, open-drain reset output with a reset delay time of 190 ms. It operates within a supply voltage range up to 2.75 V and consumes 325 nA of quiescent current. Accuracy is specified at 1.2%. The component is housed in an SOT-23-3 package and supports surface mount installation. Operating temperatures range from -40°C to +85°C.

Supervisors Feature Summary

• Provides simple reset or power-on reset functionality for monitored voltage rails
• Features an active low open-drain output interface for system control
• Designed for low-power applications with minimal quiescent current consumption

Supervisors Applications

• Industrial controls requiring voltage supervision
• Portable electronic devices needing low-power monitoring
• Embedded systems utilizing microcontrollers

Supervisors Procurement Notes

Verify the specific suffix 'TK' against official Renesas documentation, as standard listings often use 'T7A' or 'Z-T'. Confirm end-of-life status and moisture sensitivity level (MSL 3) before procurement. Ensure compatibility with existing PCB footprint and reflow profiles. Check for available replacement components if production continuity is required.

Supervisors Selection Notes

Select this component when a fixed 2.32 V threshold is required for single-channel monitoring. Consider the SOT-23-3 package size constraints and the open-drain output requirement. Verify that the 190 ms reset delay meets system timing requirements. Compare against other ISL88002 variants with different thresholds or packages if specifications do not align perfectly.

Supervisors Part Context

This part belongs to the ISL88002 series of voltage supervisors from Renesas/Intersil. These devices are designed for portable and battery-powered applications. The series offers various threshold voltages and packaging options to suit different design needs while maintaining low power consumption and high accuracy standards typical of the product line.

Supervisors Replacement Considerations

ISL88002IE23Z-T7A is a documented alternative with identical electrical characteristics but different packaging suffix.
