LDO在设计电源时很常用，说到电源，就必然要考虑的一个问题就是过流保护，过流保护是LDO电路设计中绕不过的“硬核”问题。LDO通过调节输出电压，确保负载在不同电流需求下稳定工作。但当负载电流超出设计范围，如短路或过载，过大的电流可能导致芯片 ...

[Mike Worth] wanted the option to run his Microwave Oven Transformer welding rig at less that full power. After being inspired by some of the other MOT hacks we’ve featured he figured there must be a ...

The circuit is designed for power supply protection by limiting the amount of maximum output current to prevent any further damage to take place inside the power supply as well as the external circuit ...

The importance of current limiting. A flexible solution for adding current limiting. In some power-management applications, precise current limiting is required. This is necessary either to protect ...

The USB (Universal Serial Bus) specification requires a connected USB device to present a load to the host or hub of no greater than 10 µF in parallel with 44Ω, including the effects of any bypass ...

At a power-on cycle, inrush current, if not limited, can peak to tens of even hundreds of amps when capacitive load is present, thereby increasing the probability of failure and decreasing usable ...

The new Thomas & Betts Hi-Tech 38kV Trans-Guard OS Shorty Backup Current-Limiting Fuse provides risk reduction of disruptive transformer failure. Designed for use in 26.4 to 34.5kV distribution and ...

A. An overcurrent device (typically a fast-acting fuse) that reduces the fault current to a magnitude substantially less than that obtainable in the same circuit if the current-limiting device wasn’t ...

One of the major challenges facing the electric industry is how to manage network fault levels, the magnitude of the electrical current that flows into a fault or short circuit. These current levels ...

If you’re designing a universal port, you will be expected to provide power. This was a lesson learned in the times of LPT and COM ports, where factory-made peripherals and DIY boards alike had to ...

• The inductance in a stepper-motor phase winding limits how fast current rises when power is applied. • Series-resistor current limiting needs higher voltages for faster step rates, but higher ...
