How to use L298 Motor Driver IC/Circuit Diagram The maximum allowed the current flow to draw through every output is 3a.Operating temperature ranges from -23В°c to вЂ“ 130В°c.Storage temperature ranges from -40В°c вЂ“ 150В°c.The maximum voltage supply voltage is 50v.Operating voltage ranges from +5 to +46v.The operating voltage supply is up to 46 v.The features and specifications of L298 IC include the following. 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.Pin11 (Enable B): This is an enable Input with TTL compatible.Pin10 & 12 (Inputs3 & 4): These are control inputs of bridge-B and compatible with TTL.Pin9 (Logic Voltage Supply): This pin provides voltage supply for the logic blocks.Pin6 (Enable A): This is an enable input with TTL compatible.Pin5 & 7 (Inputs): Control Inputs of the Bridge A & compatible with TTL.Pin4 (VS): This is a voltage supply pin, connected to +5V.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.Pin1 (Current Sensing A): This pin is used to control the flow of the current of the load.This IC includes dual bridges namely H-bridge A & H-bridge B. The pin configurations of L298 dual full-bridge driver IC include 15-pins where each pin is discussed below. All the enable and input pins in this IC work with 5V TTL logic to make the connection simple with different types of microcontrollers. Similarly, enable pins can also be used to make all the outputs active simultaneously. 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. Here, One H Bridge is used to switch the polarity to control the motor direction whereas pair of H bridges are used for controlling a bipolar stepper motor.Д®ach bridge in this IC includes two current sense pins like CSA & CSB and enable pins like ENA & ENB. L298 IC includes four separate power amplifiers where two amplifiers can form H-bridge A and the other two types of amplifiers can form H-bridge B. The motor driver is a small current amplifier that uses a low current signal to provide a high current signal for driving an electric motor. It is a dual full-bridge driver IC with high current & voltage, mainly designed to allow typical TTL logic levels to control different inductive loads like DC motors, solenoids, relays, stepper motors, etc. The high-power version of the L298 IC is an L293 motor driver IC. This article discusses an overview of L298 motor driver IC, working with applications. This single IC can control the motor alone but using the motor driver module by interfacing it with Arduino can make it easy. The motor driver module mainly includes a motor driver IC, which is an essential component in this module. Other DIY Projects Requiring Inductive Load Interface with Microcontroller.So this logic input is simply used to control the direction of the motor which is connected to the motor driver IC.2 DC motor/ 4 coil dual phrase stepper motor output.ДЄpplications of L298 Motor Driver Arduino Board.(HIGH NOISE IMMUNITY)Light weight, small dimension.Features of L298 Motor Driver Arduino Board An additional supply input is provided so that the logic works at a lower voltage. The emitters of the lower transistors of each bridge are connected together and the corresponding external terminal can be used for the connection of an external sensing resistor. Two enable inputs are provided to enable or disable the device independently of the input signals.

It 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.
