Introduction

XC6123F546ER-G (from here on referred to as XC6123) is a PMIC – Supervisors device that\'s controlled by a digital signal, such as a pulse-width-modulated (PWM) signal. XC6123 is specially designed to detect supply voltage and other variables from digital and analog supplies and then react accordingly.

Applications

XC6123 devices are perfect for digital systems where precision and reliability are required. XC6123 can be found in various applications such as power management, safety monitoring and overvoltage protection. It is also used to monitor output voltages of power supplies and handle power on/off sequencing.

Features

XC6123 devices feature a wide input voltage range and accurate voltage monitoring with a ± 1% accuracy. It also has a programmable reset delay with a minimum of 200 ms to a maximum of 2 seconds. The XC6123 has an integrated watchdog timer and voltage monitor, and includes a range of matching programs and conditions.

Working Principle

XC6123 works by monitoring the voltage of the supply and any other variable for which it is programmed. When it detects a change in the input voltage or a variable it is programmed to identify, it can take one of two actions: either triggering an external signal or generating an internal reset. XC6123 uses a pulse-width-modulated signal to operate. This signal varies the output voltage and adjusts the voltage according to the program. The XC6123 can also be programmed to detect when the voltage drops below a certain level and initiate a shutdown procedure.

Conclusion

XC6123 is an incredibly useful device in many digital systems. It monitors the input voltage and other variables with remarkable accuracy and can generate an external signal or initiate an internal reset when it detects a change. XC6123 includes an integrated watchdog timer and voltage monitor and provides a great range of matching programs and conditions. It provides power on/off sequencing and overvoltage protection and is perfect for applications that require precision and reliability.
