ISL88012IH531Z-TK

Supervisors Overview

The ISL88012IH531Z-TK is a dual-channel voltage supervisor IC from the Intersil ISL8801x family, housed in a SOT-23-5 package. It provides independent monitoring for two input voltages with threshold values of 3.09V and an adjustable second channel. The device features a minimum power-on reset timeout of 140ms and supports active high or active low output configurations. It integrates watchdog timer capabilities and manual reset functionality within a compact surface-mount footprint.

Supervisors Feature Summary

• Dual independent voltage monitoring channels with fixed and adjustable thresholds
• Configurable active high or active low output logic states
• Integrated watchdog timer and manual reset input functionality
• Compact five-lead SOT-23 surface-mount packaging

Supervisors Applications

• Embedded system power supply supervision
• Microcontroller reset circuit generation
• Watchdog timer implementation in industrial controllers
• Multi-voltage rail monitoring in portable electronics

Supervisors Procurement Notes

Verify component authenticity as this part is listed as no longer available or supported by the manufacturer. Confirm package integrity and pinout compatibility before integration. Check for alternative sources if current stock is unavailable due to end-of-life status.

Supervisors Selection Notes

Select this component when dual-rail supervision with configurable reset timing is required. Ensure the fixed 3.09V threshold matches one monitored rail and that the adjustable range covers the secondary voltage. Verify that the SOT-23-5 footprint fits the design constraints.
