Integrated circuit solutions have become the primary technology used in the development of a variety of applications. PMICs (power management ICs) are a popular form of integrated circuit that are utilized to power and monitor equipment in a variety of products. The XC6119N15A7R-G is a positive voltage supervisor circuit that provides system reset and power-on functions for applications such as mobile phones, PDAs and MCUs. This article will discuss the application field and working principle for the XC6119N15A7R-G.

Application Field

The XC6119N15A7R-G is a voltage supervisor circuit which functions as a reset and power-on detector for a circuit or system. It helps to protect sensitive equipment in the event of a malfunctioning or over/under voltage occurring in the system. It can also detect any sudden voltage changes in its operating power supply, and then act accordingly by resetting the circuit or system. A few notable applications of the XC6119N15A7R-G include mobile phones, PDAs, microcontrollers, audio and video equipment, automobiles and medical equipment.

The XC6119N15A7R-G is particularly fit for superior system performance. Thanks to its low power consumption, small size, low cost and low standby supply current, it is being used more and more in consumer electronics. In addition, the XC6119N15A7R-G is also suitable for applications that need to be monitored with an internal voltage supervisor, such as the voltage of a battery pack or AC-DC power supply.

Working Principle

The core of the XC6119N15A7R-G is the comparator. It is connected to two resistors and a capacitor in a voltage divider circuit. The output voltage of this circuit is compared with a voltage reference to determine the operating status of the circuit. The output of the voltage supervisor is connected to an open-drain MOSFET, which can be used to control the reset and power-on functions of the circuit or system.

When the voltage of the power supply is greater than the voltage reference, the internal ADJ output pin is pulled low, activating the MOSFET and allowing current to pass through the output, thus resetting the system. When the voltage of the power supply is below the voltage reference, the ADJ output pin is kept high, keeping the MOSFET off and preventing any current from flowing through the output. This is how the XC6119N15A7R-G helps to maintain the stability of the system.

In addition, the XC6119N15A7R-G can be connected in a variety of configurations to provide system reset and power-on functions. The reset and power-on functions can be controlled using the active low and active high input pins, as well as through the external reset signal. The active high and low input pins and external reset signals can also be combined to provide dual-level or multiple-stage reset and power-on signals.

The XC6119N15A7R-G is designed to be very easy to use. It features an adjustable reset timer to ensure that the reset signal is generated only after a specified period of time after the power is applied or the reset signal is sent. It also features an adjustable reset time-out period to protect the system against power glitches or frequent reset signals. The XC6119N15A7R-G can be configured for active low or active high outputs, which can be used with various logic levels to control the reset and power-on functions.

The XC6119N15A7R-G is a reliable and robust positive voltage supervisor circuit that can be used in a variety of applications. It is designed to provide system reset and power-on functions for a variety of systems, and its adjustable reset timer and adjustable reset time-out period make it ideal for use in consumer electronics applications.
