MAX14723ATP+T

Overview

The MAX14723ATP+T is a high-accuracy, dual-channel adjustable current limiter and power protector IC from Analog Devices. It operates within a supply voltage range of 5.5V to 60V (specifically up to 58V in some documentation) and supports an operating temperature range of -40°C to +125°C. The device is housed in a 20-WFQFN exposed pad package (4x4 mm). It provides independent overcurrent protection for two channels with adjustable thresholds.

Feature Summary

• Dual independent current limit channels for precise load protection
• Adjustable overcurrent threshold settings via external components
• High accuracy performance for reliable system safeguarding
• Exposed pad thermal enhancement for efficient heat dissipation

Applications

• Industrial equipment power distribution
• Automotive electronic systems
• Telecommunications infrastructure power management
• Consumer electronics requiring robust fault protection

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the manufacturer source is Analog Devices or Maxim Integrated to ensure authenticity. Check RoHS compliance status as indicated by the '+' suffix. Validate the 20-TQFN package dimensions against your PCB footprint requirements prior to procurement.

Selection Notes

Select this component when dual-channel independent current limiting is required for high-voltage applications up to 60V. Ensure the adjustable nature of the current limits aligns with your system's fault tolerance design. Consider the TQFN-EP package for its thermal performance in space-constrained designs requiring robust heat sinking through the exposed pad.

Part Context

This part belongs to the MAX1472x family of power protectors, which includes variants like MAX14721 and MAX14722. These devices are designed to guard systems against overcurrent faults. The MAX14723 specifically offers dual channels, distinguishing it from single-channel counterparts in the same series, providing enhanced flexibility for multi-rail power architectures.

Replacement Considerations

Direct substitutes include MAX14721ATP+T and MAX14722ATP+T, though these offer different channel counts. Verify that the replacement matches the required number of protected outputs and voltage ratings. Cross-reference pinouts and thermal characteristics to ensure compatibility with existing board layouts.
