the bootstrap capacitor value). For this application choose a CVDD capacitor with the following specifications: 1

µF , 25 V, X7R CVDD capacitor is placed across GVDD and GND pin of the gate driver. The bootstrap and bias

capacitors must be ceramic types with X7R dielectric or better. Choose a capacitor with a voltage rating at least

twice the maximum voltage that it will be exposed to. Choose this value because most ceramic capacitors lose

significant capacitance when biased. This value also improves the long term reliability of the system. The

capacitor should be rated for at least 2x the GVDD voltage, so 25V rated capacitors are recommended.
