It is a high voltage, high current dual full-bridge driver designedto acceptstandardTTLlogic levels anddrive inductive loads such as relays, solenoids, DC and steppingmotors. Two enableinputs are providedto enableor disablethe deviceindependentlyof theinput signals. The emitters of the lower transistors of each bridge are connected togetherand the correspondingexternal terminal can be used for the connectionofanexternalsensingresistor. Anadditional supply input is provided so that the logic works at a lower voltage.
