Inrush current limiters (ICLs) are devices specifically designed to help control inrush current. An inrush current is a surge of electric current when a circuit or device is first energized. The surge is caused by the fact that capacitors and other components require time to charge, so the current required to accelerate this process is much higher than the current required to maintain the charge. Inrush current can manifest as large distortion on the AC/DC supply, but it can also cause electrical overloads and even component failure due to fast-changing, excessive currents passing through the circuit.

Among the Inrush Current Limiters, MS32 0R536 has an extensive application field and a special working principle. This device is a bidirectional metal-oxide semiconductor field-effect transistor (MOSFET). It can be used for sensing, controlling, and protecting circuits in a variety of applications, including power supplies, transformers, and electronic loads. As with other MOSFETs, the MS32 0R536 has an input gate and a drain-source voltage defined by a source resistor, and it also has a built-in temperature sensor to protect the circuit from overheating.

The MS32 0R536 features an average RDS (on) of 0.02 ohms with a PWM turn-on speed of just 1us. This allows it to limit the inrush current in the circuit, preventing overload and damage. The device also utilizes a special pulse-width modulation (PWM) current-limiting algorithm to limit the current to a specific level predetermined by the user. This algorithm helps to minimize the overshoot and undershoot of the current passing through the circuit.

The MS32 0R536 is also equipped with a special voltage-drop-off (VDR) protection feature. The VDR feature will monitor the voltage across the load during power up and then engage the PWM current-limiting algorithm if the voltage exceeds a predetermined threshold. This prevents the inrush current from exceeding the maximum load level and causing component damage.

Finally, the MS32 0R536 has an integrated over-temperature protection feature. The device has a built-in temperature sensor that will detect the temperature of the device, and if it exceeds a certain level, the device will automatically shut down. This helps to protect the circuit from damaging thermal runaway.

In conclusion, the MS32 0R536 is a versatile inrush current limiter designed to help protect circuits from excessive inrush current and thermal runaway. Its high current-handling capabilities, fast turn-on speed, and integrated features make it an ideal choice for a wide variety of applications.
