MAX14586ETA+T

Overview

The MAX14586ETA+T is a power protection IC designed for input voltage monitoring and control. It features an overvoltage lockout (OVLO) function that disconnects the load when input exceeds safe limits, with a maximum protection voltage of +36V. The device incorporates a soft-start mechanism to limit inrush current during startup and includes a 15ms debounce timer to prevent false triggering from transient noise. It operates within a specified temperature range and is housed in a surface-mount package suitable for compact designs.

Feature Summary

• Integrates overvoltage lockout circuitry to protect downstream components from excessive input voltages
• Includes a soft-start feature to manage inrush current and reduce stress on power sources
• Features a programmable debounce timer to filter out transient noise and ensure stable operation

Applications

• Power supply input protection circuits
• Battery-powered device power management
• Industrial equipment power interfaces
• Consumer electronics power rails

Procurement Notes

Verify the exact suffix and tape/reel specifications against the manufacturer's official datasheet before ordering. Confirm availability status as distribution channels may vary. Ensure the procurement source provides valid traceability documentation. Check for any specific handling requirements related to moisture sensitivity levels. Validate that the component matches the intended application voltage and current ratings.

Selection Notes

Select this component when robust overvoltage protection is required for sensitive loads. Consider the OVLO threshold and hysteresis values to match the system's input voltage profile. Evaluate the soft-start timing to ensure compatibility with the power source's current capabilities. Assess the thermal performance and package size constraints for the target PCB layout. Verify compatibility with the operating temperature range of the final application environment.

Part Context
