Inrush current limiters (ICLs) are components designed to control the total amount of current that is drawn in to a device or power supply when it is first switched on, and as such they are frequently used in electronic products to improve the lifetime of circuits and other components. The MF72-005D11 is an ICL designed to limit the inrush current of an AC load to less than 5A under specified condition. Its small size and low cost make it an ideal choice for consumer applications where inrush current needs to be controlled.

The MF72-005D11’s application field includes but is not limited to consumer electronics and home appliances, industrial electronics, automotive electronics, etc.. It can protect sensitive electronic circuits from high inrush current when connected to different kinds of loads or power sources.

The MF72-005D11 current limiter is based on a integrated circuit – one precision threshold voltage generator, one precision current source, a high speed driver, a latching relay and a AC line voltage detector. It can be easily integrated into any circuit using just a few external components to facilitate the inrush current control of equipment and thus significantly reduce the risk of failure.

In terms of work principle, the MF72-005D11 ICL is based on the principle of time-stagger of two amplifiers. When the AC line voltage is detected, the first amplifier is turned on. Depending on the detection result, the second amplifier will be keep on light after a period of time. When this internal time delay is finished, the two amplifiers can regulate the current between the power supply and the load.

The precision current source and high speed driver maintains a adjustable current through the relay, which needs a pulse width modulation signal generated by the driver. The near-zero impedance of the relay ensures there is constant current control regardless of line voltage or load current variations.

In conclusion, the MF72-005D11 inrush current limiter is an ideal choice for controlling inrush current in various applications. Its integrated circuit design provides a high power limit (up to 5A) and the precise current limit setting makes it an optimum cost-effective solution for consumer electronics, home appliances and industrial applications where inrush current protection is necessary.
