Application Field

The auirf6218strl is ideal for low voltage load switch applications. As it is logic level compatible and has a PWM-compatible drive voltage range up to 18V, it is ideal for switching motors, lamps, relays, and solenoids. It can also be used as a switching power converter to control high current applications, such as HVAC and industrial motor control systems. Additionally, it is a great choice for battery powered systems, such as drones, laptops and smartphones, as it offers extremely low on-resistance and an acceptable tradeoff between power consumption and switching performance.

Working Principle

The auirf6218strl utilizes a two-terminal design, with a drain and a gate. The device is able to conduct current from the drain to the source in continuous or pulsed modes if the gate-to-source voltage is greater than VGS(th), which is the threshold voltage for the device. The device is able to block current from the drain to the source whenever the gate voltage falls below the threshold voltage. The device is also protected from over-voltage and over-current conditions by its integrated Schottky body diode and its temperature-sensing structure. Additionally, the device features a high input impedance, which allows it to achieve high switching speeds and good signal fidelity.

The auirf6218strl is designed to have an extremely low on-resistance, which allows it to transition at a very low voltage, allowing it to be powered by a wide range of logic signals and PWM controllers. Additionally, the device features an innovative package design, which helps optimize thermal performance for applications with high power density.
