UC3524DG4 is a high performance pulse width modulation (PWM) controller integrated circuit (IC) from NXP. Being a DC-to-DC switching controller for an array of application fields, the maximum supply voltage for it is 24V. It has tach input, deadtime, cold-starting and brown-starting for motor drive, hence making it suitable for application fields such as programmable logic controllers, automotive applications and PC power supplies.

Application Fields

One of the main application fields of a UC3524DG4 controller is programmable logic controllers (PLCs), which are used to automate a range of industrial tasks like metal cutting and milling. In a PLC, the UC3524DG4 can perform various functions like, pulse-width modulating, pulse-width counting, pulse-width compensation and several other tasks. This versatile integrated circuit is also used in the power supplies of a PC as a switch mode power supply. Lastly, the UC3524DG4 is widely used in automotive applications like motor drives, RF control car and power assist.

Working Principle

The working principle of a UC3524DG4 controller involves producing pulses of variable widths, which are in turn used to control the speed and direction of motors. These pulses are obtained from oscillator output signals, and the frequency of them determines the speed of the motor. Additionally, the UC3524DG4 controller is also capable of supplying power to the motor in the form of linear current and voltage limits. Therefore, it can be said that the UC3524DG4 controller acts as an intermediary between the power source, and the motor.

The UC3524DG4 IC also incorporates several useful features like tach input, deadtime, cold- and brown-starting, which give it an edge over other PWM controllers. The enable/disable tach input feature helps in allowing adjustment of the motor speed depending on the actual rotational speed, while the deadtime feature makes it easier to achieve preferred soft-start conditions. The cold-start feature helps in detecting the actual position of the motor, while the brown-start feature is used to detect the presence of an asynchronous motor.

Conclusion

In conclusion, it can be said that the UC3524DG4 controller is a versatile, high-performance PWM IC from NXP. Its features like tach input, deadtime, cold- and brown-starting make it suitable for an array of application fields, such as programmable logic controllers, PC power supplies and motor drives for automotive applications.
