DESCRIPTION
The L298 is an integrated monolithic circuit in a 15-
lead Multiwatt and PowerSO20 packages. It is a
high voltage, high current dual full-bridge driver designedto acceptstandardTTL logic 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 correspondingexternalterminal can be used for the connectionofanexternalsensingresistor.Anadditional
supplyinput is provided so that the logic works at a
lower voltage.
