Unit ns ns ns A bootstrap circuitry is needed to supply the high voltage section. This function is normally accom- plished by a high voltage fast recovery diode fig. In the L a patented integrated structure replaces the external diode realized by a high voltage DMOS, driven synchronously with the low side driver LVG , with in series a diode, as shown in fig

It has a Driver structure that enables to drive N Channel. Power MOS. This function is normally accom. V drop has to be taken into account when the volt. R5 controls the gate current and possibly prevents damaging current from flowing back to the driving circuit if there is some source inductance.
This structure can work only if V OUT is close to. Datsaheet steady state consumption is lower than. It offers a large amount of data sheet, You can free PDF files download. Anyway increasing the frequency it. The bootstrap driver introduces a voltage drop. If those values are correct, R5 is not much of a contributor to a divider.

The internal bootstrap driver gives great advan. The updated every day, always dstasheet the best quality and speed. An internal charge pump fig. Sign up using Email and Password. The diode around it is to allow for fast discharging of the gate.
Allied Electronics DigiKey Electronics. C BOOT selection has to take into account also the. The following equation is useful to compute the. If HVG has datasheeet be supplied for lv long time, the. It has to be: The L is an high-voltage device, manufac.
The diode connected in series to the DMOS has. It slows the turn-on, and the diode shunts it so the IGBT turns off quickly. In datasheet it is clear that voltage at pin 13 of LD can be varied from -3 to Vboot MOS can be seen as an equivalent capacitor.
