ISL88001IE29Z-T

Supervisors Overview

The ISL88001IE29Z-T is a low-power voltage supervisory circuit manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 1.8 V to 5.5 V and features a threshold voltage of 2.92 V. The device provides an open-drain output type with a reset delay time of 190 ms. It has an accuracy of 1.2% and consumes a typical operating supply current of 350 nA. The component is housed in an SC-70-3 package and supports surface-mount installation. It functions as a single-input voltage supervisor without manual reset or watchdog timer capabilities.

Supervisors Feature Summary

• Provides precise voltage supervision for single-input power rails
• Features ultra-low quiescent current consumption for energy efficiency
• Delivers reliable reset signals with defined delay characteristics

Supervisors Applications

• Portable electronic devices requiring extended battery life
• Embedded systems needing compact voltage monitoring solutions
• Industrial control circuits demanding high accuracy supervision

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing. Confirm the 'E' designation aligns with the required RoHS compliance standards for your region. Check manufacturer documentation for any recent product change notices affecting labeling or specifications. Ensure the SC-70-3 package dimensions match your PCB footprint requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with open-drain output is required. Consider the 2.92 V threshold specifically for 3.3 V system supervision. Evaluate the 190 ms reset delay against your system startup timing constraints. Compare the 350 nA current draw against other supervisors if power budget is critical. Verify compatibility with your target operating temperature range of -40 C to +85 C.
