DESCRIPTION
The TDF1779A is a dual source driver delivering
hihg outputcurrents and the capabilityto drive highly
inductive loads (Electrovalves, contractors, re-
lays...).
This device is essentially blow-out proof, each out-
put is protected against short-circuits. If internal dis-
sipation becomes too high, drivers will shut down to
prevent excessive heating. An ”ALARM” output is
provided to indicate the action of the thermal protec-
tion. To reactivate the power outputs, the reset input
must be forced to low state.
”SENSE” information of both power outputs are
ORed together and then processed internally.
A ”STROBE” input is also provided to offer the pos-
sibility of disabling the power outputs.
