ISL88002IE26Z-T

Supervisors Overview

The ISL88002IE26Z-T is a voltage supervisory circuit manufactured by Renesas Electronics Corporation, designed for monitoring single-input power rails. It operates within a supply voltage range of 1.8 V to 5.5 V and features a threshold voltage of 2.63 V. The device provides an open-drain reset output with a typical reset delay time of 190 ms. It exhibits high accuracy of 1.2% and consumes a low operating supply current of 350 nA. The component is housed in an SC-70 (SOT-323) package and supports surface-mount installation. It functions reliably across an extended temperature 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 compatible with various logic families
• Designed for ultra-low power consumption suitable for battery-operated systems

Supervisors Applications

• Industrial control systems requiring voltage supervision
• Portable electronic devices needing low-power monitoring
• Embedded systems utilizing microcontrollers with external reset requirements

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging if required for automated assembly. Confirm RoHS compliance status as per the latest manufacturer documentation. Check for End-of-Life notices, as this component family may be subject to discontinuation. Ensure moisture sensitivity level handling procedures are followed during storage and soldering. Validate that the SC-70-3 footprint matches the target PCB design constraints.

Supervisors Selection Notes

Select this part when a fixed threshold near 2.63 V is required for system supervision. Consider the open-drain output configuration for compatibility with different logic voltage levels. Evaluate the 190 ms reset delay against system startup timing requirements. Compare the 350 nA quiescent current against stricter low-power alternatives if battery life is critical. Ensure the SC-70 package size fits within the available board space constraints.

Supervisors Part Context

This component belongs to the ISL88002 series of voltage supervisors from Renesas. The series offers various threshold voltages to accommodate different rail monitoring needs. These devices are categorized under PMIC supervisory circuits. They are commonly used in conjunction with microcontrollers and other digital logic to ensure stable operation during power transitions.

Supervisors Replacement Considerations

Check for direct substitutes within the ISL88002 series with matching threshold voltages. Verify pinout compatibility for SC-70 packages before substitution. Confirm electrical specifications such as reset delay and accuracy meet original design requirements.
