STmicroelectronics (ST) group was established in June 1988 as a result of the merger of SGS Microelectronics of Italy and Thomson Of France.

L298 motor driver specs drivers#

With so many motor drivers currently such as Servo Motors and stepper motors, what really are the differences between the motor drivers and which one to choose? No worries, as we have crafted a table just for you to compare the various motor drivers so you know which motor driver fits the best for your project. In this way, we can control the motor rotation using the L298 chip. If both buttons are pressed or released simultaneously the MOTOR comes to stop immediately. With that MOTOR rotates anti-clockwise direction. If only Q2 is pressed, the current flows from OUT2 to OUT1. With that MOTOR rotates clockwise direction. So if only Q1 is pressed, the current flows from OUT1 to OUT2. If itвЂ™s pulled to ground the bridge-A will be disabled no matter the input control logic.ДЄfter all the circuit are setup we need to press the buttons Q1 and Q2 to change the flow of current between pins OUT1 and OUT2. The enable pin is pulled high through a resistor so bridge-A will be functioning all the time. The four diodes are FLYBACK diodes used for protecting the IC form inductive voltage spikes. These logic inputs are provided by Microcontroller or Microprocessor in application circuits. As shown in the circuit we have two push buttons Q1 and Q2 which act as controls inputs for bridge-A. Here we are using one of H-BRIDGES of l298 IC. The chip is preferred when control unit can only provide TTL outputДЄlso, the chip does not need any additional components to be installed for operating.ДЇor understanding the working of L298 IC, consider the simple circuit configuration shown below.Where current control and PWM operable single-chip device is needed.In the marked, there are H-bridges like L293 which are used for the low powered application while L298 is specially designed for the high power applications. Where a high power motor driver is required.L298 is basically used where H- BRIDGE is required.Here are a few areas where L298 is preferred: Logical вЂњ0вЂќinput voltage up to 1.5V( high noise immunity).Able to drive a two-phase stepper motor, four-phase stepper motor or two DC motors.2 enable control terminals to enable or device without inputting signals.when current control and PWM operable single-chip device is needed.when the control unit can only provide TTL outputs.when high power motor driver is required.when it is needed to operate different loads like motors and solenoid etc where an H-Bridge is required.Two enable inputs are provided to enable or disable the device independently of the input signals. It is a high voltage, a 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. The L298 is an integrated monolithic circuit in a 15-lead Multiwatt and PowerSO20 packages.
