Connection with the system controller
On board there is a 40 pins connector for the control signals. The driver board uses 26 pins. The remaining
pins are for the sensing board (IRCS2277S) that can be connected on top of IRMD22381Q board.

BOARD CUSTOMIZATION
This demo board is meant to be flexible for self-customization. Place for many spare components allow
verifying functionality of the gate driver under different external configurations.
This section will go through the possible customizations of the board.
Bootstrap circuit
The high side floating supply (VBS) is provided by a bootstrap capacitor. Figure 4 shows the circuit on board.
