TDF1778 DUAL 2-A SOURCE DRIVER

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 becomes too high, drivers will shut down .

TDF1778 Features

* This application protected against short circuits. The load disconnection is detected when inputs E1 and E2 are low and the sense output is high. When thermal protectionis activatedthe pin 9 islow. Inputs and outputs are TTL comptable. 7/10 TDF1778 TDF1778 HIGH CURRENT APPLICATION WITH INDUCTIVE
