The L298 is a high voltage, high current dual full-bridge driver designed to accept standard TTL logic levels and drive inductive loads such as relays, solenoids, DC and stepping motors.
It is available in Multiwatt and PowerSO20 packages and has a total DC current of up to 4A with low saturation voltage and overtemperature protection.
The device operates with a supply voltage of up to 46V and has high noise immunity for logical "0" input voltage up to 1.5V.
It features two enable inputs to independently enable or disable the device, and the emitters of the lower transistors of each bridge are connected together.
The L298 also provides additional supply input for logic working at a lower voltage.
The pin connections, functions, absolute maximum ratings, thermal data, electrical characteristics, and application information are also provided in the summary.
Additionally, the summary includes suggestions for using the L298, such as the need for a non-inductive capacitor, a sense resistor, and a very short path for connecting each input.
The summary also includes application information for driving inductive loads, bidirectional DC motor control, and two-phase bipolar stepper motor control.
Finally, the summary provides outline and mechanical data for the L298.
