5.2.2

Minimum deadtime

The device guarantees a minimum deadtime value of tDT, imposing a delay between the turn-off of an external

MOSFET and the turn-on of the complementary one.

The deadtime is not added to the one eventually imposed by the MCU, as shown in Figure 15.

tDT

The feature is disabled clearing the DTMIN bit (see Table 17) or when the interlocking is disabled (see

Section 5.2.1 ).

5.2.3

Sink/source current

The output stage of the gate drivers provides a maximum sink/source capability of 1 A.

The voltage to current characteristics of the gate driver output stage is described by Figure 26 and Figure 27.

When in UVLO condition, the gate drivers keep their outputs low with the maximum current capability available.
