DESCRIPTION
PowerSO20
Multiwatt15
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 standard TTL logic levels and drive
inductive loads such as relays, solenoids, DC and
stepping motors. Two enable inputs are provided to
enable or disable the device independentlyof 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-

nection ofanexternal sensing resistor. An additional
supply input is provided so that the logic works at a
lower voltage.
