MAX14571EUD/V+

Overview

The MAX14571EUD/V+ is a supervisory circuit from the MAX1457x series, designed for adjustable overvoltage and overcurrent protection. It features an integrated FET with a typical on-resistance of 100mΩ. The device supports a wide input voltage range from 4.5V to 36V. It includes programmable overvoltage lockout (OVLO) and undervoltage lockout (UVLO) thresholds via external resistors. The part operates within a temperature range of -40°C to +85°C and is housed in a TSSOP-14 package.

Feature Summary

• Adjustable overvoltage and undervoltage lockout thresholds using external resistors
• Integrated low on-resistance power FET for efficient current handling
• Configurable overcurrent protection with automatic retry functionality
• Reverse current protection and thermal shutdown capabilities

Applications

• Battery-powered systems requiring robust fault protection
• Consumer electronics infrastructure
• Industrial equipment power distribution
• Marine electronic devices

Procurement Notes

Verify component authenticity through authorized channels due to limited supply status. Confirm RoHS compliance and lead times with distributors. Ensure ESD handling protocols are followed during installation. Check for obsolescence notices or lifecycle changes from Analog Devices before finalizing procurement plans.

Selection Notes

Select this component when adjustable high-voltage protection is required. Compare against MAX14572 for latching behavior or MAX14573 for continuous current limiting if retry is unsuitable. Ensure external resistor values align with desired OVLO/UVLO thresholds. Verify package compatibility with PCB layout constraints.

Part Context

Part of the MAX1457x family of overvoltage and overcurrent protectors. Shares functional similarities with MAX14572 and MAX14573 but differs in fault response behavior. Designed for high-side switching applications where precise voltage monitoring and current limiting are critical for system integrity.

Replacement Considerations

MAX14572EUD/V+ offers similar protection with latching shutdown instead of auto-retry. MAX14573EUD/V+ provides continuous current limiting mode. Verify pinout and threshold configurations match application requirements before substitution.
