6.
The above are only recommendations. Each application is differ-
ent and may encounter different sensitivities. A driver running
with a few amperes will be less susceptible than one running with
150 A, and each design should be tested at the maximum current,
to ensure any parasitic effects are eliminated.

tance.
Ensure that the TEST pin is connected to AGND. This pin is
used for production test only.
