12.3. Functional Description
The Application Specific Power Drivers (ASPD, Figure 12-1) module handles power driving for power control
applications. The PAC5225 has three low-side gate drivers (DRLx), three high-side gate drivers (DRHx). 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.
Figure 12-2 below shows typical gate driver connections and Table 23 shows the ASPD available resources. The PAC5225
gate drivers support up to a 70V supply.
