ISL88003IH31Z-TK

Supervisors Overview

The ISL88003IH31Z-TK is a low-power voltage supervisory circuit manufactured by Renesas Electronics. It monitors a single input with a threshold voltage of 3.07 V and an overvoltage threshold of 3.112 V. The device features an active high, push-pull reset output and operates within a supply voltage range up to 5.5 V. It includes a reset delay time of 190 ms and maintains an accuracy of 1.2%. The component functions in temperatures from -40°C to +85°C with a typical operating supply current of 350 nA.

Supervisors Feature Summary

• Provides precise voltage supervision for single-input systems with defined threshold levels
• Delivers active high push-pull reset signals without requiring manual intervention
• Operates with ultra-low power consumption suitable for battery-sensitive applications

Supervisors Applications

• Low power voltage supervision in portable electronic devices
• System monitoring in industrial control equipment
• Voltage oversight in consumer electronics and IoT modules

Supervisors Procurement Notes

Verify the specific suffix designation carefully during procurement. Datasheets indicate that the T7A suffix denotes tape and reel packaging, while other suffixes may differ. Confirm package type and availability status directly with authorized distributors, as this component may have limited stock or end-of-life status. Ensure the ordering part number matches the required electrical characteristics and packaging format exactly.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with an active high push-pull output is required. It is suitable for designs needing a fixed threshold near 3.07 V with minimal quiescent current. Consider the SOT-23 package constraints and the absence of a watchdog timer if system reliability requires additional fault detection mechanisms beyond simple voltage monitoring.

Supervisors Part Context

This part belongs to the ISL88003 series of supervisory circuits from Renesas. It is designed for low-power applications where accurate voltage tracking is critical. The series typically offers various threshold options and output configurations to suit different system requirements. This specific model provides a fixed threshold solution for standard voltage rails.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the same family. Verify that substitute parts match the 3.07 V threshold and active high push-pull output configuration. Ensure replacement components support the same operating temperature range and supply voltage limits.
