Inrush current limiters (ICLs) are components that are used in electric circuits to protect against damage caused by current surges or inrush current. ICLs are designed to limit and control current during the powering up of a circuit. The MS15 40004 is a highly reliable, thermally matched, wide voltage, rugged ICL die that is available in both SOT-23 and SOT-223 packages. This article will discuss the application field and working principle of the MS15 40004 in detail.
Application Field
The MS15 40004 is suitable for a variety of applications, including power supplies, electronic ballasts, automotive systems, and industrial control. This ICL die is well-suited for applications requiring accurate current limiting over a wide temperature range from -40°C to +125°C with no physical components. When the MS15 40004 is incorporated into a circuit, it helps protect the other components from sudden current surge. It is robust and highly reliable, making it a great choice for applications requiring precise current limiting all the time.
Working Principle
The MS15 40004 utilizes a proprietary technology to control and limit current. The technology is based on semiconductor chip technology and utilizes N-channel MOSFET devices to control current. The N-channel MOSFETs are connected in an integrated circuit in a way that allows for precise control of current. The MS15 40004 utilizes thermal matching techniques to ensure that the current limiting is uniform over the specified temperature range. The current limiting occurs when the MS15 40004 receives power from the associated circuit. When power is applied, the MS15 40004 limits the current until a desired limit is reached. After the current limit is reached, the MS15 40004 will reduce the current to a safe level. This allows the associated circuit to remain functional and not be damaged by any large surges of current.
Conclusion
The MS15 40004 is a highly reliable and robust Inrush Current Limiter die. It is suitable for a wide range of applications, from power supply to industrial control. This ICL die uses thermal-matched semiconductors combined with a proprietary current control technology to precisely limit the current. This helps to protect circuits from damage caused by inrush current. The MS15 40004 is a great choice for applications requiring uniform current limiting over a wide temperature range with no physical components.
