Power protection switches & controllers

With the growth of AI and cloud computing, server power and reliability needs increase exponentially. With our feature-rich eFuses and hot-swap controllers, you can design reliable server power systems at higher power levels. eFuses and hot-swap controllers also protect data from power transients in vital memory systems, and are available in space-conscious and power-efficient packages.

Benefits:

• High power density.
• Comprehensive protections during overvoltage, overcurrent and overtemperature events.
• Wide voltage range and PMBus options for more tailored solutions.

As the power demands driven by AI infrastructure increase, data center network switches require reliable power protection and precise control to maintain system uptime, scalability, and efficient distribution across network cards and control subsystems.

Benefits of 48V eFuses and hot-swap controllers:

• Input power protection features maintain stable operation
• Fault isolation protects infrastucture by containing electrical faults at the circuit level and preventing cascading failures
• System-level telemetry provides real-time visibility into system conditions, greatly reducing troubleshooting time

Due to the increase in processing power in electronic control units (ECU), traditional protection solutions such as Schottky diodes and P-channel field-effect transistors (FETs) are no longer as viable. Our ideal diodes protect downstream devices and systems with high system efficiency, improved thermal management and a very small solution size.

Benefits:

• Reverse polarity and current protection, inrush current control, and overcurrent and short-circuit protection.
• Small, power-dense packaging.
• Internal or external FET options.

Simplify your input protection designs using highly integrated TI eFuses with flexible protection thresholds. Protect against reverse current and reverse polarity events with ideal diode controllers or back-to-back FET eFuses. For low-voltage systems with two inputs, power muxes help acheive seamless switchover.

Benefits:

• Design flexibility from adjustable slew rate, overvoltage and overcurrent protection and selectable fault responses.
• Reduce system downtime with integrated fault diagnostics and accurate current monitoring.
• Decrease system size with compact footprints.

Automated climate control, security and lighting solutions continue to grow sharply in homes and workspaces. TI power muxes provide small, low-power solutions to transition between power sources. Ideal diode controllers protect against miswiring during installation and ideal diode bridge rectifiers improve efficiency in 24VAC and 48V power-over-ethernet (PoE) systems.

Benefits:

• Low quiescent current and small packages to increase battery life and reduce size.
• Automatic switchover to reduce system complexity.
• Ideal diode bridge solutions for decreasing power losses versus Schottky bridges.

Our input protection portfolio prioritize two key aspects of PC power-supply designs: small form factors and protection against transient events. TI eFuses protect your designs without sacrificing size. For seamless switchover between battery and USB charging, TI power muxes offer protection and low leakage in small packages. 

Benefits: 

• Wide voltage ranges and protections against overcurrent, overvoltage and reverse current.
• Compact packaging, with options smaller than 5 mm².
• Low quiescent currents for increased battery life.
