PRODUCTION DATA
Select a ceramic capacitor CHB1 = CHB2 = 0.1 to approximately 0.22 µF, placed close to the HB and SW pins. The fast switching diode of the forward current rated at 1-A and reverse voltage not lower than VHV_max must be selected as the bootstrap diode, through which the boot capacitor CHB1 or CHB2 is charged by VCC. To reduce the noise caused by the fast charging current, a 2-Ω to 5-Ω current limiting resistor must be placed in series with each boot diode.
