12.3. Functional Description
The Application Specific Power Drivers (ASPD, Figure 12-1) module handles power driving for power control
applications. PAC5250 has six low-side gate drivers (DRLx), three ultra-high-voltage high-side gate drivers (DXHx), two
medium-voltage open-drain drivers (OMx). Each gate driver can drive an external MOSFET or IGBT switch in response to
high-speed control signals from the microcontroller ports, and a pair of high-side and low-side gate drivers can form a half-
bridge driver. The open-drain drivers provide activation control for relays, LEDs, buffers, and other loads.
Figure 12-2 below shows typical gate driver connections and Table 21 shows the ASPD resources available on PAC5250.
