The L6398DTR is a motor driver integrated circuit, which is designed to provide full bridge function to PWM motor control. It is a component of a three-phase motor driver, which can drive medium and high power motors operating at a wide range of starting voltage and doing full-bridge outputs. The chip offered by ST MICROELECTRONICS is widely used in the field of industrial automation, Consumer and Commercial Motors, Motor Control & Robotics.

The application field of the motor driver IC is wide and varied, ranging from industrial robots and medical devices to solenoids and even CNC machines. This IC can also be utilized for several types of other applications such as controlling variable speed drive, remote control, and glider speed regulation. The IC can also be used for driving BLDC motors, BLDC trapezoidal motors, and combined stepper motors.

The chip boasts a very simple and cost-effective solution that can be utilized in a wide range of driving and controlling motors. The L6398DTR motor driver IC has advanced thermal protection and current sensing functions, which makes it very reliable and efficient. It is capable of handling peak currents up to 4.25A RMS when it is supplied with a voltage between 4.5 and 12V.

The working principle of the L6398DTR is based around two simple operations. The first is a signal trapping mechanism, which is used to ensure the safe and reliable operation of the motor driver. This mechanism makes sure that the voltage always stays within the required safe limits, which helps to ensure the safety of the motor and the driver IC itself. The second operation is the actual PWM control, which is used to control the speed of the motor.

The signal trapping mechanism works by constantly monitoring the input of the motor driver IC. If the motor controller is supplied with an overcurrent condition, the voltage will be increased to a level where the motor driver can handle it safely. Similarly, if the voltage drops too low, the signal trapping mechanism will reduce the voltage, thus ensuring the safe operation of the motor driver.

The PWM control in the motor driver IC is used to control the speed of the motor. The motor speed can be adjusted according to the input of the user. This implementation also makes sure that the motor runs at the optimum efficiency level, while at the same time avoiding overloading of the motor. This ensures the safe operation of the motor.

Overall, the L6398DTR motor driver IC is a great choice for a wide range of applications. Its advanced features make it easy to integrate into most motor control applications. It is reliable and affordable, and can handle peak currents up to 4.25A RMS. This makes it a great choice for embedded solutions, as it has a very small footprint.
