ISL88001IH22Z-TK

Supervisors Overview

The ISL88001IH22Z-TK is a single-channel voltage supervisor IC manufactured by Renesas Electronics Corporation. It monitors a single input voltage with a threshold of 2.19V. The device features an open-drain reset output that is active low. It operates within a supply voltage range of 1.8V to 5.5V and has a minimum reset timeout of 140ms. The component is housed in a SOT-23 package and supports surface mount installation. The operating temperature range extends from -40°C to +85°C.

Supervisors Feature Summary

• Monitors a single power supply rail for undervoltage conditions
• Provides an active-low open-drain reset signal upon fault detection
• Ensures system stability with a guaranteed minimum reset timeout period

Supervisors Applications

• Industrial control systems requiring power supervision
• Embedded systems needing simple reset generation
• Portable electronics utilizing low-voltage power sources

Supervisors Procurement Notes

Verify the specific suffix 'TK' against official Renesas documentation to confirm tape-and-reel packaging details. Confirm RoHS compliance status and check for any Product Change Notifications (PCN) related to labeling or manufacturing site updates. Ensure the source document explicitly lists this exact part number to avoid confusion with similar variants like the IE17Z or IE23Z series.

Supervisors Selection Notes

Select this component when a single-channel supervisor with an open-drain output is required. The 2.19V threshold suits applications monitoring standard logic levels. Consider the SOT-23 package for space-constrained designs. Verify that the open-drain output configuration aligns with the downstream circuit's pull-up requirements and voltage levels.

Supervisors Part Context

This part belongs to the ISL88001 family of voltage supervisors. It shares functional similarities with other members like the ISL88002 and ISL88003, which may offer different thresholds or additional features. The family is designed for industrial controls and general-purpose power management tasks requiring reliable reset generation.
