IRF9620STRR

The IRF9620STRR is a single high power N-Channel MOSFET device. This N-Channel MOSFET is made of common source, current sensing resistor and source follower arrangements. It has an exceptionally high drain-source breakdown voltage and gate-source voltage. It is mainly used as a power switch in various applications including high voltage power management, motor control, general-purpose motor control and short-circuit protection. This article provides a brief introduction of the application field and working principle of IRF9620STRR.

The IRF9620STRR is a popular device used in many high-power applications. Its main application is to provide power switching capability in demanding situations like high voltage power management, motor control, general-purpose motor control and short-circuit protection. The device provides excellent control in switching high-voltage polarities. It also provides robust control during over-current or short-circuit protection situations. It can be used as a simple inrush current limiter in power supplies and as a high-side switch in DC-DC converters. It can also be used as a simple power switch for switching on and off loads in electronic equipment.

The IRF9620STRR operates on the principle of the common source, current sensing resistor and source follower arrangement. It has an exceptionally high drain-source breakdown voltage and gate-source voltage. The gate voltage is applied to two MOSFETs. One MOSFET is equipped with a current sensing resistor and the other has a direct connection between source and gate. The current flowing in the resistor is sensed by the gate of the first MOSFET, and the second MOSFET is used to reduce the voltage drop across the resistor. The gate voltage of the first MOSFET is dynamically regulated depending on the load current through the MOSFET. The voltage drop on the current sensing resistor also determines the turn-on/off of the MOSFET. If the voltage across the resistor is below a certain value, the gate turns off, preventing the current from increasing further.

The source follower circuit, on the other hand, is used to provide a better current flow. The voltage on the source is kept constant at a value lower than the gate, allowing the current to flow freely. The source follower also eliminates the power wasted in a static voltage drop and reduces the on-resistance of the MOSFET. It also provides improved temperature stability and faster switching speeds. The combination of the main MOSFET and the source follower, along with the current sensing resistor, provides a reliable and powerful high-power switching device.
