Introduction:

TC642BEOA application field and working principle belong to PMIC (Power Management Integrated Circuit) - motors drivers, controllers. PMICs are used for managing power and for other specialized functions required by system designers. PMICs are available for digital, analog, mixed-signal, wireless, and motor control applications.

Application Fields:

TC642BEOA is a PMIC specifically designed for motor control applications. It is an intelligent dual full-bridge motor driver based on a mix of analog and logic circuits for controlling and producing the correct power device switching polarities. This allows the TC642BEOA to control and drive two bidirectional DC brush motors, as well as managing the power sequencing and sequencing of parallel connected motors.

The TC642BEOA is ideal for applications such as lightly loaded motors, small robotics, quadcopters, and LED lighting. Additionally, the TC642BEOA offers a higher level of performance compared to conventional motor drivers, making it suitable for high-end applications, such as industrial automation, automotive and medical.

Working Principle:

The TC642BEOA utilizes the advanced gate driver technology for controlling and driving the two bidirectional DC Brush Motors. The internal high speed gate drivers include all the necessary protection features (under voltage, over voltage, overcurrent, thermal protection, etc.), and significantly reduce the power losses common in power devices. The internal oscillator allows for adjustable frequency operations up to 20MHz, for optimized efficiency and system compatibility.

The TC642BEOA includes two (2) input channels for external PWM control, allowing for easy and flexible motor control applications. Each PWM channel features separate rising and falling slope controls, as well as an adjustable blanking time. In addition, the driver features Fault indications, RDS(ON) monitoring, and an external clock input.

The TC642BEOA also offers the ability to adjust dead time compensation and a programmable current limit. The adjustable current limit ensures that the peak current is below a predetermined value, protecting the system from potential fault conditions while still allowing higher performance in multiple motor applications.

Conclusion:

In conclusion, the TC642BEOA PMIC is a highly efficient and reliable solution for motor control applications. The motor driver is suitable for both lightly loaded and high performance applications, thanks to its adjustable frequency operations, adjustable current limits, and programmable dead time compensation. Because of the wide range of features that the TC642BEOA offers, it is the perfect choice for robotic and quadcopter applications, as well as industrial, automotive and medical applications.
