BOOTSTRAP DRIVER bootstrap circuitry needed supply high voltage section. This function normally accomplished high voltage fast recovery diode (fig. 8a). L6388 patented integrated structure replaces external diode. realized high voltage DMOS, driven synchronously with side driver (LVG), with series diode, shown fig. internal charge pump (fig. provides DMOS driving voltage diode connected series DMOS been added avoid undesirable turn CBOOT selection charging choose proper CBOOT value external seen equivalent capacitor. This capacitor CEXT related total gate charge gate gate ratio between capacitors CEXT CBOOT proportional cyclical voltage loss CBOOT>>>CEXT e.g.: Qgate 30nC Vgate 10V, CEXT 3nF. With CBOOT 100nF drop would 300mV. supplied long time, CBOOT selection take into account also leakage losses. e.g.: steady state consumption lower than 200µA, 5ms, CBOOT supply CEXT. This charge capacitor means voltage drop internal bootstrap driver gives great advantages: external fast recovery diode avoided usually great leakage current).

long enough charge capacitor. bootstrap driver introduces voltage drop DMOS RDSON (typical value: Ohm). frequency this drop neglected. Anyway increasing frequency must taken account. following equation useful compute drop bootstrap DMOS: gate drop dson drop dson where Qgate gate charge external power MOS, Rdson resistance bootstrap DMOS, Tcharge charging time bootstrap capacitor. example: using power with total gate charge 30nC drop bootstrap DMOS about Tcharge 5µs. fact: 30nC drop 0.8V Vdrop taken into account when voltage drop CBOOT calculated: this drop high, circuit topology doesn't allow sufficient charging time, external diode used.
