6ED family - 2nd generation
Technical Description

AN-EICEDRIVER-6EDL04-1
A similar consideration must be done for the high side supply circuit. The loop of pins VBx, the bootstrap
capacitor C
BS
, and the pin VS must also be small. Otherwise, there may be inductive voltage drops during the
gate charging process of turn-on, which may result in spontaneous undervoltage lockout events at the high side
section.
Finally, the inductances of the DC link tracks can be partially cancelled, if one places a low impedance film
capacitor between the positive and negative rail closely to the transistor terminals as shown in Figure 14 with
C
DC
.
