PMIC supervisors incorporate a wide variety of functions, including voltage monitoring and reset generation. The X5643S14, developed by Excellon Automation, is a comprehensive voltage supervisor solution that integrates a voltage detector, clock oscillator and reset generator. It is designed to monitor various voltage levels in the system, provide reset signals when needed, and enable electronic functions that require precise timing and accuracy. This article will discuss the application field and working principle of the X5643S14.

Application Field

The X5643S14 is a multi-functional voltage supervisor which can be used in a variety of applications. It can be used as an internal voltage detector and output reset signal when the voltage drop below a certain level. Moreover, it can generate precise clock signals and be applied in clocking or timing control applications, such as embedded MCUs, digital switches and DC motors. Furthermore, it is suitable for automotive, industrial and consumer electronic systems where precise voltages must be monitored.

Working Principle

The X5643S14 voltage supervisor comprises three main functional blocks – an analog voltage detector, a clock oscillator and an output reset generator. The voltage detector monitors the input voltage and provides an analog output signal proportional to the system voltage. The clock oscillator generates a precise clock signal with frequency adjustable up to 128kHz. The output reset generator consists of two separate reset signals, which can be programmed to different thresholds, and these reset signals can be generated when the system voltage drops below the threshold level.

The X5643S14 voltage supervisor is easy to set up and requires minimal external components. It is available in a 3.9mm x 4.76mm QFN package, allowing it to be easily mounted on circuit boards when space is limited.

In summary, the X5643S14 is a comprehensive voltage supervisor solution that can be used in a variety of applications. It integrates a voltage detector, clock oscillator and reset generator, allowing it to monitor voltage levels, generate precise clock signals, and provide reset signals when needed. With its small footprint and low power requirements, it is an ideal solution for space-restricted environments and systems requiring low power consumption.
