MaxLinear Expands AI Infrastructure Portfolio with Intelligent eFuse Solutions for Rack-Scale Power Protection and Telemetry

CARLSBAD, Calif. — MaxLinear, Inc. (NASDAQ: MXL), a leader in high-performance analog, mixed-signal, and connectivity semiconductor solutions, today announced the expansion of its AI infrastructure portfolio with two new 16V high-current electronic fuse (eFuse) solutions, the MxL745950 and MxL745951P. Designed for the power demands of next-generation AI infrastructure, the new devices combine high-current protection, power-path monitoring, fault isolation, and telemetry to help customers build more reliable and serviceable rack-scale systems.

Introducing MaxLinear’s intelligent eFuse solutions — delivering power protection, telemetry, and fault isolation for next-generation AI infrastructure.

As AI deployments evolve from server-centric architectures toward increasingly dense, rack-scale systems, power management is becoming a critical component of overall infrastructure reliability. AI servers and accelerator platforms are placing greater demands on power delivery, while networking equipment, fan trays, power shelves, storage systems, and other rack resources are creating increasingly complex power domains.

MaxLinear’s new eFuse solutions are designed to help hyperscalers, OEMs, ODMs, and networking equipment providers protect and monitor these critical power paths. By integrating high-current power switching with protection, sensing, and monitoring capabilities, the devices can help customers improve system uptime, isolate faults, simplify serviceability, and gain greater visibility into power behavior across AI infrastructure.

Intelligent Power Protection for AI Infrastructure

Traditional power protection approaches can require multiple discrete components to provide current monitoring, fault protection, hot-swap functionality, and power-path control. As AI systems become more power-dense, these approaches can increase board complexity and consume valuable space.

MaxLinear’s eFuse architecture integrates key protection and monitoring functions into compact devices, helping designers simplify power-path implementation while supporting higher current levels and more sophisticated system monitoring.

The MxL745950 is a 16V, 50A eFuse featuring 1mΩ on-resistance in a compact 5mm × 5mm LGA-32 package. It integrates current sensing, temperature monitoring, fault indication, programmable soft-start, and parallel-operation capability. These features make it suitable for applications including AI servers, networking systems, accelerator platforms, and plug-in modules where high-current power protection and compact implementation are essential.

The MxL745951P extends these capabilities with a 16V, 60A stackable eFuse featuring 0.79mΩ on-resistance, PMBus™/I²C interface support, high-precision telemetry, configurable protection thresholds, non-volatile fault recording, and active current balancing during startup and steady-state operation.

The MxL745951P provides digital telemetry for input voltage, input current, input energy, output voltage, output current, input power, and output power. This enables system designers to integrate detailed power-domain information into broader management and monitoring architectures, supporting more intelligent operation of AI and high-performance computing infrastructure.

Addressing the Power Challenges of Rack-Scale AI

AI infrastructure is undergoing a fundamental shift as compute resources are increasingly deployed and managed at the rack level. A single rack may include multiple accelerator trays, compute nodes, high-speed networking systems, power shelves, cooling equipment, and management controllers. Each subsystem can introduce unique power requirements and potential failure modes.

In this environment, power protection is no longer simply a component-level function. It is becoming an important part of the rack-level control and management architecture.

MaxLinear’s intelligent eFuse solutions are designed to help customers address several key requirements:

Rack-level fault isolation: Integrated protection and fault-management capabilities can help isolate failures within individual power domains and reduce the risk of broader system disruption.
Greater operational visibility: High-precision telemetry and fault recording provide insight into power-domain behavior and can help accelerate troubleshooting and root-cause analysis.
Scalable current handling: High-current operation, parallel connectivity, and active current balancing support increasingly dense AI systems and higher-power accelerator platforms.
Improved serviceability: Hot-swap and inrush-control capabilities can help support maintenance and replacement operations in service-sensitive infrastructure.
Control-plane integration: Power monitoring and protection complement MaxLinear’s broader portfolio spanning connectivity, console access, monitoring, telemetry, rack management, power management, and protection.

“As AI infrastructure scales, the opportunity is expanding beyond compute silicon into the control, power, and telemetry technologies required to operate dense racks reliably,” said Amit D. Bavisi, Ph.D., Senior Vice President and General Manager, Analog Mixed-Signal Business Unit at MaxLinear. “Our new eFuse solutions extend MaxLinear’s role across AI servers, accelerator trays, switches, fan trays, power shelves, and rack-level platforms by helping customers build more observable, serviceable, and resilient power architectures.”

Key Features for AI Data Center Power Protection

The new eFuse solutions provide several capabilities optimized for high-performance infrastructure applications:

High-current capability: Up to 50A with the MxL745950 and up to 60A with the MxL745951P, with parallel-operation support for higher-current designs.
Low-loss power path: Integrated MOSFETs with low on-resistance help minimize power dissipation and voltage drop in high-current applications.
Hot-swap and inrush control: Programmable or configurable soft-start helps manage inrush current during card insertion and backplane hot-plug events.
Comprehensive protection: Integrated undervoltage protection (UVP), overvoltage protection (OVP), overcurrent protection (OCP), short-circuit protection (SCP), overtemperature protection (OTP), MOSFET fault diagnosis, and fault reporting support system protection.
Advanced telemetry: The MxL745951P adds PMBus/I²C connectivity, high-precision current monitoring, configurable thresholds and timers, non-volatile configuration, and black-box fault recording.
Compact implementation: The MxL745950 is offered in a 5mm × 5mm LGA-32 package, while the MxL745951P is available in a 5mm × 4.5mm VQFN-26L package, supporting space-constrained system designs.
