PRODUCTION DATA
The primary purpose of the VCC capacitor is to supply the peak transient currents of the driver and bootstrap capacitor and provide stability for the VCC regulator. The value of CVCC must be at least 10 times greater than the value of CBST, and must be a good quality, low-ESR ceramic capacitor. CVCC 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.
