MAX16027TP+T

Supervisors Overview

The MAX16027TP+T is a triple-voltage supervisory circuit with capacitor-adjustable thresholds, operating from 2.2V to 28V. It provides fixed thresholds for 3.3V, 2.5V, 1.8V, 1.5V, and 1.2V systems, alongside adjustable thresholds with 1.5% accuracy for voltages down to 0.5V. Fixed threshold precision remains at 2.7% across the temperature range. The device features an open-drain or open-collector output, a 140ms reset timeout, and operates between -40°C and +125°C in a 20-TQFN (4x4) package.

Supervisors Feature Summary

• Capacitor-adjustable thresholds enable monitoring of low voltages down to 0.5V with high precision
• Integrated sequencing capabilities support complex power-up and power-down sequences
• Open-drain or open-collector output simplifies interface with various logic families

Supervisors Applications

• Monitoring multiple voltage rails in embedded systems
• Power sequencing for multi-rail FPGA and processor designs
• Supervisory circuits for industrial control equipment

Supervisors Procurement Notes

Verify the suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the '+' designation ensures compliance with lead-free manufacturing standards. Ensure the specific threshold configuration matches the required application voltages, as the device supports both fixed and adjustable options depending on external components.

Supervisors Selection Notes

Select this component for applications requiring precise monitoring of three distinct voltage levels. The adjustable threshold feature offers flexibility for non-standard voltages, while fixed options simplify design for common rails. Consider the 20-TQFN package size for space-constrained layouts and verify thermal performance within the specified operating temperature range.

Supervisors Part Context

This part belongs to the MAX16027 family of supervisory circuits designed for multi-voltage systems. It integrates sequencing and monitoring functions into a single compact package. The device is suitable for replacing discrete supervisor solutions, reducing component count and board space in modern electronic designs.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio that offer similar threshold configurations. Verify that any substitute maintains the same operating voltage range and package dimensions to ensure mechanical compatibility.
