Gate driver

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.

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 or N-Channel type devices, by either pulling down to ground (P-channel) or up to ground (N-channel devices).

Source / Sink Current Value

The amount of current the device is expected to source / sink to bring the gate down. The Gate Driver supports four selectable gate drive levels: 1 ľA, 3 ľA, 10 ľA, and 30 ľA.

Gate Driver Port Name

The name of the signal assigned to this gate driver. It appears as the final port name in the generated system.
