电源保护开关与控制器

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

随着 AI 基础设施驱动的功率需求不断增长，数据中心网络交换机需要可靠的电源保护和精确控制，来维持系统正常运行时间、可扩展性，并在网卡和控制子系统之间高效分配。

48V 电子保险丝及热插拔控制器的优势：

• 输入电源保护功能可保持稳定运行
• 故障隔离通过在电路级别控制电气故障并且防止级联故障来保护基础设施
• 系统级遥测可提供对系统状况的实时可见性，从而大大缩短故障排除时间

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

我们的输入保护产品组合优先考虑 PC 电源设计的两个关键方面：小尺寸和瞬态事件保护。TI 电子保险丝可在不影响尺寸的情况下为您的设计提供保护。为了在电池和 USB 充电之间实现无缝切换，TI 电源多路复用器采用小型封装，可提供保护和低泄漏。

优势：

• 宽电压范围和过流、过压及反向电流保护。
• 紧凑型封装，可选择小于 5mm² 的封装。
• 低静态电流，可延长电池寿命。
