MAX16550GPN+T

Specialized Overview

The MAX16550GPN+T is a protection IC designed for the distribution, control, monitoring, and protection of system 12V power supplies. It integrates a low-resistance N-channel MOSFET with a total resistance of 1.9mΩ (including package) and features lossless current-sense circuitry. The device operates within a supply voltage range of 10.8V to 13.2V and supports a maximum load current of 30A. It utilizes an internal LDO providing a 1.8V bias supply. Control and telemetry are managed via an SMBus/PMBus interface. The component is housed in an 18-pin FCQFN package.

Specialized Feature Summary

• Monolithic integration of power, control, and monitoring functions within a compact footprint.
• Patented lossless current sensing provides high-accuracy reporting across varying loads and temperatures.
• Programmable soft-start capability limits inrush current during startup sequences.
• Multi-level overcurrent protection including moderate, severe, and safe OCP thresholds.

Specialized Applications

• Servers
• Networking equipment
• Storage systems
• Communication equipment
• AC/DC power supplies

Specialized Procurement Notes

Verify the specific suffix GPN+ against official manufacturer documentation to confirm package type and RoHS compliance status. Confirm availability through authorized distributors as lead times may vary. Ensure the ordering information matches the exact part number required for the design.

Specialized Selection Notes

Select this component for applications requiring integrated e-fuse functionality on a 12V bus. Consider the thermal characteristics and junction-to-case resistance when designing the PCB layout. Verify that the PMBus/SMBus interface requirements align with the system controller capabilities.

Specialized Part Context

The MAX16550 belongs to the Maxim Integrated family of integrated protection ICs. It serves as a direct replacement for discrete circuit breaker or e-fuse solutions, offering reduced board area consumption compared to conventional designs while maintaining precise monitoring and fast fault isolation capabilities.

Specialized Replacement Considerations
