IC
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 de-signed to accept standardTTL logic levels and drive inductive loads such as relays, solenoids, DC and stepping motors. Two enableinputs are provided to enable or disable the deviceindependentlyof the in-put signals. The emitters of the lower transistors of each bridge are connected together and the corre-sponding external terminal can be used for the con-nectionof an externalsensing resistor. An additional supply input is provided so that the logic works at a lower voltage.
