ISL88002IE29Z-TK

Supervisors Overview

The ISL88002IE29Z-TK is a voltage supervisory circuit manufactured by Renesas Electronics Corporation. It features a single monitored input with an open-drain active-low reset output. The device operates within a supply voltage range of 1.8 V to 5.5 V and has a threshold voltage of 2.92 V. Key electrical parameters include a reset delay time of 190 ms, quiescent current of 350 nA, and accuracy of 1.2%. The component is housed in a SOT-23-3 surface-mount package and supports reel or cut tape packaging formats.

Supervisors Feature Summary

• Provides simple reset and power-on reset functionality for single-channel voltage monitoring
• Features low quiescent current consumption suitable for battery-powered applications
• Delivers an active-low open-drain reset signal without manual reset capability

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Battery-operated systems needing voltage supervision
• Embedded circuits utilizing low-power microcontrollers

Supervisors Procurement Notes

Verify the specific suffix 'TK' against official Renesas documentation to confirm packaging details such as reel quantity and moisture sensitivity level. Ensure compatibility with existing PCB footprints for the SOT-23-3 package. Confirm end-of-life status and lead times through authorized distributors prior to finalizing procurement plans.

Supervisors Selection Notes

Select this component when a low-power supervisor with a 2.92 V threshold is required. Compare against other ISL88002 variants if different voltage thresholds or output configurations are needed. Consider the 190 ms reset delay and 1.2% accuracy for timing-sensitive designs.

Supervisors Part Context

This part belongs to the ISL88002 series of voltage supervisors from Renesas. The series offers various threshold voltages and packages to support diverse embedded system requirements. The IE29Z variant specifically targets applications needing precise supervision at approximately 2.92 V.

Supervisors Replacement Considerations
