The device also features a number of built-in safety features, including over-temperature protection, clip detection, and protection against over-current, under-voltage, and over-voltage. An integrated watchdog timer and motor PWM generator ensure reliable operation, even in the most demanding applications.

Applications of the L6228QTR

The L6228QTR offers a variety of useful features for a wide range of applications, including automotive, electric, and white goods. The device is well-suited for use in gate drives, brushless AC and DC motors, fan motors, and other motor driving applications. The MCK feature of the L6228QTR is also useful for educational purposes, as the Motor Control Educational Kit allows developers to get up and running quickly with the included sample programs. The device is also used in commercial applications related to motor control, such as robotics and CNC machine control.

Working Principle of the L6228QTR

The L6228QTR controller and driver module offers reliable motor control. The integrated microcontroller acts as both a processor and a signal generator, with the signal generated by the MCK algorithm. This signal is then used to generate a PWM signal which is sent to the motor. The PWM signal can be adjusted using the MCK’s range of internal functions, which can be programmed by the user. The device also contains an integrated circuitry that monitors the motor’s condition, providing protection against over-heating and over-currents.

The L6228QTR also contains several analog and digital peripherals, including an integrated 8-channel 12-bit Analog-to-Digital Converter (ADC). This can be used to measure parameters such as temperature and voltage during operation. The device also contains several digital inputs and outputs, which can be used with external sensors or other external devices. The L6228QTR also supports several interfaces such as USB, CAN, and FlexRay. This makes it easy to connect to other devices, including other motor controllers, and control them from one place.
