Power management integrated circuits (PMICs) are used in a variety of applications, from automotive to IoT. They provide the power needed to keep the microcontrollers and other systems running. Supervisors are one kind of PMICs which are responsible for helping the systems detect and control the power conditions of the system. X4043S8IT2 is a recently released supervisor featured with low voltage and micro-power consumption. This article will discuss X4043S8IT2’s application field, working principle as well as its advantages and disadvantages.

Application Fields of X4043S8IT2

X4043S8IT2 is designed for low voltage and micro-power consumption applications. It can be used in a variety of applications including automotive, IoT devices, medical, industrial and consumer. It features with 3-V to 5.5-V input voltage range, adjustable reset tie-off voltage, and an independent watchdog timer. It also provides a system-level signal to signal error status, power-on reset (POR) signal, and supervisory detection.

Working Principle of X4043S8IT2

The X4043S8IT2 is based on a voltage monitoring system. It monitors the supply voltage for a given device and if that voltage falls below a certain pre-determined level, it will activate the reset signal. This reset signal can be used to reset the device to ensure that it does not malfunction. When the voltage rises above the pre-determined level again, the reset signal will remain active for a certain amount of time to ensure that the device has enough time to fully restart.

The X4043S8IT2 has a “watchdog timer” which can also be used for monitoring the system. The watchdog timer will continuously monitor the system, and if it detects any irregularities, it will trigger a reset signal. This reset signal can be used to reset the device and prevent it from malfunctioning.

Advantages and Disadvantages of X4043S8IT2

X4043S8IT2 has several advantages compared to other supervisors. Firstly, it has very low power consumption. It only consumes 0.0128 microamps and that’s not a lot. Secondly, it has a wide operating temperature range from -40°C to 125°C so it can be used in environments with harsh temperatures. Thirdly, it features an adjustable reset tie-off voltage which provides great flexibility. Last but not least, it reduces EN pin current draw and helps to improve system level EMI/RFI performance.

The only disadvantage of X4043S8IT2 is its limited current rating. It can only provide a maximum of 500 mA. For applications that require higher current ratings, other supervisors may be better suited.

Conclusion

X4043S8IT2 is a recently released supervisor with low voltage and micro-power consumption. It can be used in a variety of applications including automotive, IoT devices, medical, industrial and consumer. It features with 3-V to 5.5-V input voltage range, adjustable reset tie-off voltage, and an independent watchdog timer. X4043S8IT2 has several advantages such as its low power consumption, wide operating temperature range, adjustable reset tie-off voltage, and improved system level EMI/RFI performance. The only disadvantage of this supervisor is its limited current rating of 500 mA.
