CROSS CONDUCTION
Although the device guarantees the absence of cross-conduction, the presence of the intrinsic diodes in
the POWER DMOS structure causes the generation of current spikes on the sensing terminals.
This is due to charge-discharge phenomena in the capacitors C1 & C2 associated with the drain source
junctions (fig. 1). When the output switches from high to low, a current spike is generated associated with
the capacitor C1. On the low-to-high transition a spike of the same polarity is generated by C2, preceded
by a spike of the opposite polarity due to the charging of the input capacity of the lower POWER DMOS
transistor (see fig. 2).
