Infineon IRLML2244TRPBF N-Channel MOSFET: Key Specifications and Applications

The Infineon IRLML2244TRPBF is a highly efficient N-Channel MOSFET utilizing advanced TrenchFET® technology, designed to deliver superior performance in a compact SOT-23 package. This MOSFET is engineered for low voltage, high-speed switching applications, making it a popular choice in modern electronic designs where space and power efficiency are critical.

A key specification of the IRLML2244TRPBF is its low threshold voltage (VGS(th)), typically around 1.35V, which allows it to be driven easily by low-voltage GPIO pins from microcontrollers or logic circuits. With a drain-source voltage (VDS) of 12V and a continuous drain current (ID) of 3.7A, it is robust enough to handle significant power relative to its size. Its ultra-low on-resistance (RDS(on)) of just 45mΩ at 4.5V gate drive ensures minimal conduction losses, leading to higher efficiency and reduced heat generation. The device also features a fast switching speed, which is crucial for applications involving high-frequency PWM signals.

The applications of the IRLML2244TRPBF are extensive. It is commonly used in power management circuits, such as DC-DC converters and voltage regulation modules, where efficient power conversion is required. Its fast switching capability makes it ideal for load switching in portable devices, including smartphones, tablets, and wearable technology. Additionally, it is employed in motor control circuits for small brushed DC motors, as well as in LED drivers for brightness control. In computing, it can be found on motherboards and GPUs for power distribution tasks.
