Current sense pins can be tied to ground but we can also insert low value resistor and its voltage reading is proportional to current. They can be 1N5819 schottky diodes or 1N4001 rectifier diodes.Д®ach bridge is provided with enable pins (ENA, ENB) and current sense pins (CSA, CSB). To avoid that voltage spikes there should be some internal parasitic or Flywheel diodes. Pair of H Bridge is used to control a bi-polar stepper motor.Д«asically L298N is used to drive inductive or magnetic loads, so there can come voltage spikes in output. One H bridgeВ is used to switch the polarity in controlling direction of DC motor.

Two of them form H-bridge A while other two form H-bridge B. L298N consists of four independent power amplifiers. The pin diagram in top view for L298N is given below: Motor Driver Internal Circuit Logical вЂњ0вЂќ Input Voltage up to 1.5 V PIN DIAGRAM of L298N.It can drive inductive loads e.g relays, solenoids, motors (DC and stepping motor), etc. It is a high current dual full-bridge driver that is designed to accept standard TTL logic levels. L298N is an integrated circuit multi watt 15 package and capable of giving high voltage.
