Supervisors are an important part of the power management integrated circuit (PMIC) family. They provide power supply monitoring, reset sequencing, and other specialized functions to ensure proper system operation, and are designed with the precise handling of digital information requirements. X4163PZ is a popular PMIC supervisor, with excellent performance in applications such as microcontrollers, smart home control, and security systems. This article will look at the X4163PZ and analyse its application field and working principle.

X4163PZ Application Field

The X4163PZ is designed to provide precision voltage monitoring, reset generation, and instantaneous current limit protection, particularly for automotive or industrial applications. Its 0.4% monitoring accuracy combined with an operating temperature range of -25°C to +85°C make it ideal for these applications. In terms of compatibility, the X4163PZ supports various kinds of microcontrollers, such as 8051, PIC16, PIC12, AVR, and various types of embedded processors. Its large selection of operating voltages (from 1.9V to 5.5V) and reset thresholds (from 1.25V to 5.4V) make it suitable for a wide range of microcontroller applications. It is also compatible with several external output devices, such as PWM, LEDs, and LCDs, making it the perfect choice for a wide range of prominent industrial, automotive, and smart home applications.

X4163PZ Working Principle

The X4163PZ is based on a voltage detection circuit with an MOS comparator, and a Schmitt Trigger buffer circuit. This allows it to accurately detect and compare the input and output voltages, such as when the input voltage goes below the specified threshold, the voltage detection circuit will turn off the power supply, and therefore reset the microcontroller. The Schmitt Trigger buffer circuit is then used to prevent any false triggering of the voltage detection circuit. If the input voltage rises back above the threshold, then the voltage detection circuit will turn on again, allowing the normal microcontroller operation to continue. Additionally, the X4163PZ is also equipped with an instantaneous current limit protection system, which will detect and shut off any overloads or short circuits, thereby protecting the microcontroller from harm.

Conclusion

The X4163PZ power management integrated circuit supervisor is a powerful and popular tool for industrial, automotive, and smart home applications. Its wide operating voltage and reset threshold range make it suitable for a variety of microcontrollers, while its voltage detection circuit and current limit protection system enable accurate and safe operation. In conclusion, the X4163PZ offers excellent performance and reliability in any application, helping to ensure the smooth operation of any digital device.
