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 de-
signed 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 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-

Fun ction
Between this pin and ground is connected the sense resistor to
control the current of the load.
Outputs of the Bridge A; the current that flows through the load
connected between these two pins is monitored at pin 1.
Supply Voltage for the Power Output Stages.
A non-inductive 100nF capacitor must be connected between this
pin and ground.
TTL Compatible Inputs of the Bridge A.
TTL Compatible Enable Input: the L state disables the bridge A
(enable A) and/or the bridge B (enable B).
Ground.
Supply Voltage for the Logic Blocks. A100nF capacitor must be
connected between this pin and ground.
TTL Compatible Inputs of the Bridge B.
Outputs of the Bridge B. The current that flows through the load
connected between these two pins is monitored at pin 15.
