Each bridge in this IC includes two current sense pins like CSA & CSB and enable pins like ENA & ENB. Here, current sense pins are connected to the ground terminal but we can also include a low-value resistor where its voltage reading is relative to the current. Similarly, enable pins can also be used to make all the outputs active simultaneously Pin Configuration: The pin configurations of L298 dual full-bridge driver IC include 15-pins where each pin is discussed below. This IC includes dual bridges namely; H-bridge A & H-bridge B. Pin1 (Current Sensing A): This pin is used to control the flow of the current of the load. Pin2 & 3(Output 1 & 2): These two pins are output pins of the H- Bridge A where the current supplies throughout the load which is monitored at pin-1 Pin4 (VS): This is a voltage supply pin, connected to 5V. Pin5 & 7 (Inputs): Control Inputs of the Bridge A & compatible with TTL Pin6 (Enable A): This is an enable input with TTL compatible Pin8 (GND): This is a GND pin Pin9 (Logic Voltage Supply): This pin provides voltage supply for the logic blocks. Pin10 & 12 (Inputs3 & 4): These are control inputs of bridge-B and compatible with TTL Pin11 (Enable B): This is an enable Input with TTL compatible Pins 13 & 14 (Output 3 & 4): These are output pins of the H- Bridge B where the flow of current throughout the load is monitored at pin15.
