The primary purpose of the V_CC capacitor is to supply the peak transient currents of the driver and bootstrap capacitor as well as provide stability for the V_CC regulator. The value of C_VCC must be at least 10 times greater than the value of C_BST, and must be a good quality, low-ESR, ceramic capacitor. C_VCC must be placed close to the pins of the IC to minimize potentially damaging voltage transients caused by the trace inductance. A value of 2.2 µF was selected for this design example.
