Gate driver topology – L6388

Due to current value in bootstrap charge, the internal diode cannot be used, thus external

diode SMBY01-400 [20.] must be used. Further details on L6585 and L6588 application can

be found in [18.] and [19.].

4.3.1

Totem pole

In order to match inherent power devices characteristics, (as high gate charge) with drivers

current capability, totem pole STS01DTP06 [21.] in a push pull configuration is used in the

application. The STS01DTP06 is housed in the SMD dual island SO-8 package and allows

an optimized electronic solutions, by improving circuit efficiency, saving space and reducing

component count on the board.

The STS01DTP06 is a hybrid complementary NPN and PNP bipolar transistor

manufactured using the latest low voltage planar technology. Extremely efficient

performance is obtained by combining high pulse current, excellent gain and fast speed,
