® L298 DUAL FULL-BRIDGE DRIVER . . . . . OPERATING SUPPLY VOLTAGE UP TO 46 V TOTAL DC CURRENT UP TO 4 A LOW SATURATION VOLTAGE OVERTEMPERATURE PROTECTION LOGICAL ”0” INPUT VOLTAGE UP TO 1.5 V (HIGH NOISE IMMUNITY) Multiw att15 PowerSO20 DESCRIPTION The L298 is an integrated monolithic circuit in a 15lead Multiwatt and PowerSO20 packages. It is a high voltage, high current dual full-bridge driver designed to accept standardTTL logic levels and drive inductive loads such as relays, solenoids, DC and stepping motors. Two enableinputs are provided to enableor disable the deviceindependentlyof the input signals. The emitters of the lower transistors of each bridge are connected together and the corresponding external terminal can be used for the conBLOCK DIAGRAM O RDERING NUMBERS : L298N (Multiwatt Vert.)
