DESCRIPTION
TheTDF1778is adualsourcedriverdeliveringhigh
output currents and capable to drive any type of
loads (Electrovalves, contactors,lamps).
This deviceis essentiallyblow-out proof,eachout-
put isprotectedagainstshort-circuits.Ifinternaldis-
sipationbecomestoo high,drivers will shutdownto
prevent excessive heating. An ”ALARM” output is
providedtoindicatetheactionofthethermalprotec-
tion.Toreactivatethepoweroutputs,theresetinput
mustbe forced to low state.
”SENSE” information of both power outputs are
ORed togetherand then processedinternally.
A ”STROBE” input is alsoprovidedto offerthepos-
sibility of disabling the power outputs.
