ISL88012IH523Z-TK

Supervisors Overview

The ISL88012IH523Z-TK is a dual-channel voltage supervisor from the Intersil family, housed in a compact SOT-23-5 package. It monitors two independent input voltages and provides flexible output configurations via open-drain and push-pull drivers. The device supports multiple fixed threshold options including 2.32V, 2.5V, 3V, 3.3V, and 5V, alongside an adjustable variant. It operates within a supply range of 2.2V to 6V and features a reset delay time of approximately 140ms. The component functions reliably across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Dual-channel monitoring capability for independent voltage supervision
• Flexible output driver configuration supporting both open-drain and push-pull modes
• Multiple selectable threshold voltage options with adjustable variants available

Supervisors Applications

• Multi-rail power system supervision in embedded controllers
• Voltage monitoring for portable electronic devices requiring compact footprints
• Industrial control systems needing reliable dual-voltage oversight

Supervisors Procurement Notes

Verify the specific suffix code against official Renesas/Intersil documentation to confirm exact threshold voltage selection and output type. Ensure the ordering part number matches the required pinout and functional specifications for your design. Cross-reference datasheet revisions to confirm compatibility with current manufacturing standards.

Supervisors Selection Notes

Select this component when dual voltage supervision is required in space-constrained designs. Compare threshold accuracy and reset delay times against other single-channel supervisors if only one rail needs monitoring. Consider the output drive strength requirements when choosing between open-drain and push-pull configurations for interfacing with downstream logic.

Supervisors Part Context

This device belongs to the ISL8801x series of voltage supervisors designed for low-power applications. It complements single-channel models like the ISL88011 by offering dual-input supervision in a similar small outline transistor package. The series targets cost-sensitive markets requiring reliable power management without complex external components.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the ISL8801x family that offer different threshold combinations. Verify electrical characteristics such as quiescent current and reset delay when substituting with other dual-supervisor ICs from different manufacturers.
