Hi team,
Figure 67 of THS3491 datasheet is shown in the figure below. In the upper part of the figure is N-MOSFET, whose source is connected to the highest potential +VS. Even if the maximum output of ths3491 is +VS and connected to the gate of N-MOSFET through 2.49 Ω resistance, the VGS of N-MOSFET must be less than or equal to 0. The condition for N-MOSFET to turn on is that VGS is greater than a positive threshold voltage. Is N-MOSFET in the figure unable to conduct?
Similarly, the P-MOSFET in the figure also has this problem.
