The XC6119C47A7R-G PMIC (power management IC) is a type of supervisor device. It is designed for efficient voltage monitoring so that it can support the proper working of a system. This article will explain the application field of the XC6119C47A7R-G and the working principle behind it.

The main application area of the XC6119C47A7R-G is in portable devices, such as smartphones, digital cameras and portable media players. This PMIC is especially suitable for the monitoring of the voltages in battery powered devices because it operates effectively at low supply currents. The XC6119C47A7R-G features a programmable channel for the monitoring of a variety of power supplies and/or system parameters. It also provides multiple short circuit protection and supports reset time delay.

The working principle behind the XC6119C47A7R-G is based on the comparisons between two separate voltage levels. The input to the PMIC is a reference voltage, which will be the threshold level for the comparison. This reference voltage is usually fixed for the XC6119C47A7R-G. The second input is the actual voltage of the power source being monitored. The inputs will be compared to each other and, if the second voltage feed exceeds the reference voltage, a signal will be sent to an external output pin.

This signal will be used to switch devices on or off, begin the reset process or alert the user when a fault is detected. The XC6119C47A7R-G has a built-in delay, so that when it is engaged, a timer will start and the device will stay in the state it was in before the voltage exceeded the predetermined threshold. This delay process also prevents false triggering and damaging surges due to short power cycles.

The XC6119C47A7R-G PMIC is an effective voltage supervisor for portable devices such as smartphones and digital cameras. It operates with extremely low current draw and is configurable for many different operating parameters. The device’s working principle is based on the comparison of the input voltage to a reference voltage. If the voltage exceeds the designed threshold, the XC6119C47A7R-G will output an alarm signal and activate the safety functions in order to support the proper operation of the system.
