ISL88002IH31Z-T

Supervisors Overview

The ISL88002IH31Z-T is a low-power voltage supervisory circuit manufactured by Renesas Electronics (formerly Intersil). It monitors a single input with an undervoltage threshold of 3.038 V and an overvoltage threshold of 3.112 V. The device features an open-drain reset output, operates within a supply voltage range of 1.8 V to 5.5 V, and consumes 0.35 µA of operating supply current. It functions reliably across a temperature range of -40 °C to +85 °C and is housed in a SOT-23 package.

Supervisors Feature Summary

• Provides precise monitoring of a single power rail using dedicated undervoltage and overvoltage thresholds.
• Delivers system reset signals via an active-low open-drain output pin for reliable interface compatibility.
• Designed for ultra-low power consumption suitable for battery-operated or energy-efficient applications.

Supervisors Applications

• Low-power voltage supervision in portable electronic devices
• System reset generation in embedded industrial control units
• Power management protection in IoT sensor nodes

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required threshold voltage specifications for your target application circuit design.

Supervisors Selection Notes

Select this component when a single-channel supervisory function with open-drain output is required. Compare against the ISL88003 series if push-pull outputs are preferred instead. Verify that the 1.8 V minimum supply voltage aligns with your system's operational range and that the SOT-23 package fits your board layout constraints.

Supervisors Part Context

This part belongs to the ISL88002 series of low-power voltage supervisors from Renesas. It shares architectural similarities with other members like the ISL88002IH23Z-T but differs in specific threshold settings. The series is designed for general-purpose power monitoring in consumer and industrial electronics where minimal quiescent current is critical.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the ISL88002 family with different threshold voltages. Verify functional equivalence with other single-input supervisors offering open-drain outputs before substitution.
