RDSON L =
α 1.2 = 2
RDSON H =
α 0.7 = 1.15
RS = 0.36
Rtot = 12.5
VON = 26.24V
(During the chopping)
VOFF = 9.7
(During the chopping)
DC = 15.6%
Tp = 8 msec
T1 = 250

(During the phase change)
PdL = 1.1W
PdH = 0.4W
Pdch = 0.20W
Pdo = 0.24W
At last:
Ptot = 1.94W
The needed thermal resistance between junction
and ambient must be equal to:
Rthjamb =
Tjmasc
Tambmasc
Ptot
39°C/W
The worst case here considered requires an
heatsink of 25
°C/W. The calculation of the power
dissipation by considering the current imbalance
and by simulating a typical motion needed to
carry the head of a printer for example, becomes
full of difficulties. The use of the Personal Com-
puter is helpful in such a case: few examples are
shown from Fig. 28ab until Fig. 31 ab.
Each figure shows the Application Datas and one
diagram where the Total Dissipated Power versus
the peak of the motor current is plotted.
A max Ambient temperature of 70
°C and a max
junction temperature of 150
°C have been consid-
ered for a few applications using one single de-
vice and a dual device configuration to drive one
