ISL88002IE17Z-TK

Supervisors Overview

The ISL88002IE17Z-TK is a single-channel voltage supervisory circuit manufactured by Renesas Electronics Corporation. It monitors one input voltage with a threshold of 1.67V and features an active-low open-drain reset output. The device operates within a supply voltage range of 1.8V to 5.5V, consuming a typical operating current of 350nA. It provides a minimum reset timeout of 140ms and functions reliably across a temperature range of -40°C to +85°C. The component is housed in a compact SC-70 (SOT-323) surface-mount package.

Supervisors Feature Summary

• Provides simple power-on reset and undervoltage supervision for a single monitored rail
• Features an active-low open-drain reset output compatible with various logic families
• Designed for low-power applications with minimal quiescent current consumption
• Operates over a wide supply voltage range suitable for diverse system architectures

Supervisors Applications

• Industrial control systems requiring reliable power monitoring
• Portable electronic devices needing efficient voltage supervision
• Embedded systems utilizing microcontrollers or memory circuits

Supervisors Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm pinout and electrical characteristics, as variations exist within the ISL88002 family. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for end-of-life notices or product change notifications that may affect long-term availability. Ensure the selected package matches your PCB footprint design constraints.

Supervisors Selection Notes

Select this component when a single-channel supervisor with an open-drain output is required. Compare the 1.67V threshold against your system's minimum operating voltage to ensure proper reset timing. Consider the SC-70 package size if board space is limited. Verify that the 140ms minimum timeout meets your system's startup requirements. Evaluate the 350nA current draw against total power budget constraints.

Supervisors Part Context

The ISL88002 series includes multiple variants with different thresholds and packages. This specific part belongs to the IE17 sub-series indicating the 1.67V threshold. Other variants like ISL88002IE23Z offer different voltages. The T7A suffix typically denotes tape-and-reel packaging, while TK may indicate a specific reel configuration. All share the same core supervisory functionality.

Supervisors Replacement Considerations

ISL88002IE17Z-T7A is a confirmed substitute with identical electrical specifications and SC-70-3 packaging. Verify that the replacement maintains the same open-drain output configuration and reset timeout characteristics. Ensure compatibility with existing PCB footprints and assembly processes.
