ISL88012IH522Z-TK

Supervisors Overview

The ISL88012IH522Z-TK is a dual voltage supervisor IC in a SOT-23-5 package. It features one fixed voltage input and one user-adjustable input, adjustable down to 0.6V. The device provides dual RST outputs with open-drain or push-pull configurations. It includes an adjustable Power-On Reset (POR) timeout function. The component serves as a multi-voltage supervisor for monitoring supply rails.

Supervisors Feature Summary

• Dual voltage supervision with one fixed and one adjustable channel
• Adjustable POR timeout for customized startup sequencing
• Flexible output configuration supporting open-drain and push-pull modes

Supervisors Applications

• Multi-rail power system monitoring
• Embedded systems requiring adjustable reset thresholds
• Industrial control units needing watchdog-like supervision

Supervisors Procurement Notes

Verify the specific suffix Z-TK against current Renesas or Intersil availability lists, as this part number may be discontinued or superseded. Confirm the exact threshold voltage settings for the adjustable pin during design-in. Ensure the SOT-23-5 footprint matches the target PCB layout. Check for any manufacturing site change notices that might affect long-term supply continuity.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required within a compact footprint. The adjustable input allows customization of trip points without changing part numbers. Consider the output drive capability if connecting to high-capacitance lines. Verify compatibility with the system's logic levels for the RST outputs.

Supervisors Part Context

This device belongs to the ISL8801x family of supervisors from Intersil, now part of Renesas Electronics. The family offers various combinations of fixed and adjustable voltage monitors. The ISL88012 specifically targets applications needing two monitored channels with flexible reset timing.

Supervisors Replacement Considerations

Check for ISL88011, ISL88013, ISL88014, or ISL88015 equivalents if different channel counts are acceptable. Verify functional compatibility with newer Renesas-supplied versions of the same part number.
