MAX14528ETA+T

Overview

The MAX14528ETA+T is an adjustable overvoltage protector featuring a low 100mΩ (typ) internal FET. It protects systems against voltage faults up to +28V. The device offers preset internal ±2.5% accurate OVLO thresholds and an adjustable trip level. It operates within a supply voltage range of 2.2V to 28V. The component is housed in an 8-WFDFN exposed pad package.

Feature Summary

• Integrates a low on-resistance internal FET for efficient power protection
• Provides high-accuracy overvoltage lockout with preset or adjustable thresholds
• Supports input voltage protection up to +28V

Applications

• Low-voltage system protection against voltage faults
• Overvoltage protection circuits
• Power management applications requiring precise threshold control

Procurement Notes

Verify the specific suffix 'ETA' and '+T' designation to ensure compatibility with required lead frame material and tape-and-reel packaging specifications. Confirm that the exposed pad thermal requirements align with the target PCB layout design for optimal heat dissipation during operation.

Selection Notes

Select this component when precise overvoltage detection is critical for sensitive low-voltage loads. The adjustable threshold feature allows customization beyond fixed presets. Ensure the application voltage does not exceed the +28V maximum rating to maintain device integrity and reliable switching performance.

Part Context

This part belongs to the MAX14527/MAX14528 family of overvoltage protection devices manufactured by Analog Devices Inc./Maxim Integrated. These components are designed specifically to safeguard electronic systems from transient and sustained overvoltage events, integrating the protection switch directly into the IC.
