ISL88002IE29Z-T

Supervisors Overview

The ISL88002IE29Z-T is a single-channel voltage supervisory circuit manufactured by Renesas Electronics Corporation. It monitors one input voltage with a threshold of 2.92V and an accuracy of 1.2%. The device features an open-drain active-low reset output and a fixed reset delay time of 190ms. It operates within a supply voltage range of 1.8V to 5.5V, consuming 350nA of operating supply current. The component is housed in an SC-70-3 surface-mount package and supports an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides simple power-on reset functionality for monitored voltage rails
• Features low quiescent current consumption suitable for battery-powered applications
• Delivers active-low open-drain reset signal upon undervoltage detection

Supervisors Applications

• Portable electronic devices requiring efficient power monitoring
• Battery-operated systems needing brownout protection
• Embedded circuits utilizing low-voltage logic families

Supervisors Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm pinout and electrical characteristics. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Check for end-of-life notices or obsolescence announcements from the manufacturer to ensure long-term availability for production cycles.

Supervisors Selection Notes

Select this component when a precise 2.92V threshold is required for system supervision. Ensure the SC-70-3 package fits the available PCB footprint. Verify that the open-drain output interface matches the receiving logic gate requirements without additional pull-up components if not already present in the design.

Supervisors Part Context

This part belongs to the ISL88002 series of low-power voltage supervisors designed for portable electronics. The series offers various threshold voltages to accommodate different logic levels. Manufactured by Renesas, these devices integrate essential power management functions into compact packages to minimize board space usage.

Supervisors Replacement Considerations

Compatible substitutes include other ISL88002 variants with similar thresholds and SC-70-3 packaging. Verify equivalent reset delay times and supply voltage ranges before substitution.
