ISL88002IE46Z-T

Supervisors Overview

The ISL88002IE46Z-T is a single-channel voltage supervisor IC manufactured by Renesas Electronics Corporation. It monitors one input voltage and provides a reset signal when the supply drops below or exceeds specific thresholds. The device features an open-drain output type with active-low reset functionality. It operates within a supply voltage range of 1.8 V to 5.5 V and has a threshold voltage of 4.62 V. The component is housed in a SC-70-3 surface-mount package and supports a minimum reset timeout of 190 ms. It functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides simple reset and power-on reset supervision for a single monitored voltage channel
• Features an active-low open-drain output interface for flexible system integration
• Designed for low-power applications with minimal quiescent current consumption

Supervisors Applications

• Industrial control systems requiring reliable voltage monitoring
• Portable electronic devices utilizing battery-powered operation
• Embedded systems needing brown-out detection and reset generation

Supervisors Procurement Notes

Verify the exact suffix and manufacturer part number against official Renesas documentation before procurement, as variations exist within the ISL88002 series. Confirm that the specific threshold voltage and package type match your design requirements. Check for end-of-life notices or product change notifications related to this component family. Ensure compliance with RoHS3 specifications if required by your manufacturing standards.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with an open-drain output is required. Consider the 4.62 V threshold specifically for higher voltage rails within the 5.5 V maximum limit. Evaluate the SC-70-3 package size constraints against available board space. Compare the 190 ms reset timeout against system startup timing requirements to ensure proper initialization sequences are met.

Supervisors Part Context

This component belongs to the ISL88002 series of voltage supervisors from Renesas. The series offers various threshold voltages and output configurations to suit different power management needs. It is categorized under Power Management ICs (PMIC) and serves as a critical protection element in ensuring stable system operation during power fluctuations.
