ISL88002IH22Z-T7A

Supervisors Overview

The ISL88002IH22Z-T7A is a single-channel voltage supervisor integrated circuit manufactured by Renesas Electronics Corporation. It operates within an ambient temperature range of -40°C to +85°C and utilizes a surface-mount SC-70 (SOT-323) package with three terminals. The device monitors one input voltage channel with a threshold of 2.21V. It features a minimum reset timeout of 140ms and provides a low-active reset signal via an open-drain or open-collector output configuration.

Supervisors Feature Summary

• Provides simple reset and power-on reset functionality for monitored circuits
• Delivers a low-active reset signal through an open-drain or open-collector interface
• Operates reliably across industrial temperature ranges from -40°C to +85°C

Supervisors Applications

• Industrial control systems requiring voltage supervision
• Embedded systems needing power-on reset generation
• Portable devices utilizing low-voltage monitoring

Supervisors Procurement Notes

Verify the specific suffix 'IH22' corresponds to the 2.21V threshold variant in official Renesas documentation before procurement. Confirm current availability status as distribution data may indicate end-of-life or obsolescence notices for this component family. Ensure compatibility with SC-70-3 footprint requirements during design finalization.

Supervisors Selection Notes

Select this component when a fixed 2.21V threshold is required for single-supply monitoring applications. The open-drain output allows flexibility in interfacing with various logic families. Consider the 140ms minimum reset delay for system timing constraints. Verify that the SC-70-3 package size meets board space limitations compared to larger supervisor options.

Supervisors Part Context

This part belongs to the ISL88002 series of voltage supervisors, designed for cost-sensitive and space-constrained applications. The series offers multiple threshold voltages distinguished by alphanumeric suffixes. The ISL88002 family is widely used in consumer electronics and industrial equipment where reliable power management is critical for system stability.

Supervisors Replacement Considerations

ISL88002IE17Z-T7A: Different threshold voltage (1.67V). ISL88002IE23Z-T7A: Different threshold voltage (2.32V). Verify exact threshold match before substitution.
