PMIC - Power Management - Specialized

MCZ33789BAE is an innovative power management integrated circuit (PMIC) designed for automotive applications. Its purpose is to provide an efficient and cost-effective power supply for a variety of automotive applications such as lights, fans, audio systems and more. In this article, we will look at the application field and working principle of MCZ33789BAE.

Application Field

The MCZ33789BAE PMIC is designed with automotive applications in mind. It is suitable for a variety of automotive applications such as headlights, fog lights, fans, air conditioning, audio systems, and more. It can also be used in other fields, such as industrial and consumer electronics, where a reliable, compact and cost-effective power supply is needed.

Features

The MCZ33789BAE PMIC has several features that make it a great choice for automotive applications. It is equipped with a high-efficiency synchronous buck converter (up to 95%) and programmable voltage range (between 2.5V and 28V). It also has a wide voltage range from 3V to 36V, high efficiency, fast transient response, and wide temperature operation range (−40°C to +125°C).

In addition, the device has a high current drive capability of up to 3A, over-current protection, over-temperature protection, and a dedicated ENA# output that can be used to control the buck converter. The device also has a wide range of programmable settings, including phase shift, switching frequency, and overvoltage protection.

Working Principle

The MCZ33789BAE PMIC uses a synchronous buck converter which works by turning off the high-side MOSFET and turning on the low-side MOSFET. When turned on, the current through the low-side MOSFET starts to rise and the output voltage starts to increase. This process is repeated until the output voltage reaches the desired level.

The phase shift of the buck converter is set by the phase hold pin (PH#). This pin makes it possible to adjust the phase shift of the converter, thus allowing the user to optimize the efficiency of the converter. For example, a higher phase shift (i.e. more delay between the on-times of the two MOSFETs) will result in a higher efficiency of the converter.

The switching frequency of the MCZ33789BAE PMIC is selectable from 1kHz to 500kHz. It is important to choose the correct frequency for your application in order to maximize the efficiency of the system. A higher switching frequency increases the chances of EMI (electromagnetic interference) but it also improves the transient response of the converter.

Conclusion

The MCZ33789BAE PMIC is a great choice for automotive applications that require an efficient and cost-effective power supply. It has a wide voltage range, high efficiency, fast transient response, and wide temperature operation range. In addition, the device has a high current drive capability, over-current protection, over-temperature protection, and a dedicated ENA# output. The device also has a wide range of programmable settings, including phase shift, switching frequency, and overvoltage protection.
