The gate threshold voltage, VGS(th) is the minimum amount of gate-to-source voltage required to create a conducting path between the source and drain terminals of the power MOSFET. Infineon Mosfet is available in a wide range of product portfolio, and we offers a variety of options for VGS(th):
 - NL (Normal level): 2 V - 4 V
 - LL (Logic level): 1 V - 3 V
 - SLL (Super logic level): 0.5 V - 1 V

When to use logic level (LL/SLL) devices

 - In low-frequency applications, the MOSFET can be driven directly from a microcontroller, eliminating the need of an external MOSFET driver.
 - Some systems have limited bus voltages, e.g., 5 V, which require the use of LL/SLL devices.
When to use normal level (NL) devices

 - In noisy environments, the elevated threshold voltage prevents false turn-on of the MOSFET.
