MAX5993AATL+T

Overview

The MAX5993AATL+T is a supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for phase redundancy control applications. It features an I2C configurable interface to manage multiple power phases. The device operates within a supply voltage range of 2.7V to 5.5V and supports up to four redundant phases. It includes integrated fault detection and reporting capabilities via the serial interface. The component is housed in a TQFN-40 package suitable for surface-mount assembly.

Feature Summary

• Configurable multi-phase redundancy controller with I2C interface
• Integrated fault detection and status reporting
• Supports up to four redundant power phases

Applications

• Server and storage system power management
• Multi-phase DC-DC converter supervision
• Industrial power distribution units

Procurement Notes

Verify availability through authorized distributors as this part may be subject to limited supply or factory special orders. Confirm the exact suffix matches the required temperature grade and packaging format. Cross-reference the datasheet revision to ensure compatibility with existing design specifications before procurement.

Selection Notes

Select this component when designing systems requiring active load balancing and fault isolation across multiple power rails. Ensure the I2C bus speed and address configuration align with the host microcontroller. Verify that the thermal performance of the TQFN-40 package meets the application's heat dissipation requirements under full load conditions.

Part Context

This part belongs to the MAX5993 series of supervisory circuits focused on power management reliability. It complements other Maxim Integrated PMIC solutions by providing intelligent control logic rather than direct power conversion. The series targets high-reliability infrastructure where continuous operation and rapid fault response are critical for system stability.
