The Gate Driver is the analog output coming from the analog system. You can use it to drive the gate of an external MOSFET on or off. The Gate Driver is designed to work with external MOSFETs as a configurable current sink or source.
The figure below shows the Gate Driver dialog box.Figure 1-21. Output Gate Driver Dialog Box
Gate Driver Polarity - Indicates the type of MOSFET controlled by the gate driver (NMOS or PMOS). PMOS controls positive voltage supply and NMOS controls negative voltage supply. The AG pad can work with either P-Channel (pulling down to ground) or N-Channel (pulling up to ground) devices.
Signal Name - The name of the signal assigned to this gate driver. It appears as the final port name in the generated system.
Enable Name - The name of the signal that enables the gate driver.
Source Current - The amount of current the device is expected to source. The Gate Driver supports selectable current drive levels: 1 μA, 3 μA, 10 μA, 30 μA, and 25 mA.
