The TDF1779A is a dual source driver delivering hihg outputcurrents and the capabilityto drive highly inductive loads (Electrovalves, contractors, relays...). This device is essentially blow-out proof, each output is protected against short-circuits. If internal dissipation becomes too high, drivers will shut down to prevent excessive heating. An "ALARM" output is provided to indicate the action of the thermal protection. To reactivate the power outputs, the reset input must be forced to low state.
