ISL88002IH29Z-TK

Supervisors Overview

The ISL88002IH29Z-TK is an ultra-low power voltage supervisor manufactured by Renesas Electronics Corporation. It monitors a single input voltage with a threshold of 2.92 V and an overvoltage threshold of 2.96 V. The device features an active low, open-drain reset output and a fixed reset delay time of 190 ms. Operating within a supply voltage range of 1.8 V to 5.5 V, it consumes only 350 nA of operating current. Accuracy is specified at 1.2%. The component is housed in a SOT-23-3 package and supports industrial temperature ranges from -40°C to +85°C.

Supervisors Feature Summary

• Ultra-low power consumption for extended battery life
• Single-channel voltage monitoring with precise thresholds
• Active low open-drain reset output configuration
• Compact surface-mount packaging options

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Battery-operated systems needing voltage supervision
• Industrial control circuits with strict power constraints
• Embedded systems utilizing low-voltage logic levels

Supervisors Procurement Notes

Verify the specific suffix 'TK' indicates tape and reel packaging when sourcing. Confirm the manufacturer is Renesas Electronics Corporation, formerly Intersil. Check datasheet revisions for any updates regarding pinout or electrical characteristics. Ensure compatibility with SOT-23-3 footprint requirements during PCB layout. Validate moisture sensitivity level handling procedures if storage conditions exceed limits.

Supervisors Selection Notes

Select this component when a single voltage rail requires supervision with minimal quiescent current. The 2.92 V threshold suits applications monitoring 3.3 V or similar nominal rails. Consider the open-drain output capability for interfacing with various logic families. Evaluate the 190 ms reset delay against system startup timing requirements. Compare accuracy specifications against other supervisors in the ISL88002 series for precision needs.

Supervisors Part Context

This part belongs to the ISL88002 series of ultra-low power voltage supervisors. It complements variants like ISL88001 and ISL88003 which may offer different thresholds or packages. The series provides solutions for simple reset and power-on reset functions. Evaluation boards such as ISL88001/2/3EVAL1Z are available for testing these devices in typical application circuits.
