RDSON
is
tested
in
the
following
way:
RDSON
=
(VCC − VCBOOT1)
I1(VCC,VCBOOT1)
−
−
(VCC − VCBOOT2)
I2(VCC,VCBOOT2)
where I1 is pin 8 current when VCBOOT = VCBOOT1, I2 when VCBOOT = VCBOOT2
(**) Pin 3 is a high impedence pin. Therefore dt can be set also forcing a certain voltage V3 on this pin. The dead time is the same obtained
with a Rdt if it is: Rdt ⋅ Iref = V3.
