TDF1778
DESCRIPTION
The TDF1778 is a dual source driver delivering high output currents and capable to drive any type of loads (Electrovalves, contactors, lamps). This device is essentially blow-out proof, each output is protected against short-circuits. If internal dissipation bees 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. ”SENSE” information of both power outputs are ORed together and then processed internally. A ”STROBE” input is also provided to offer the possibility of disabling the power outputs. PIN CONNECTION
