<h3> Application Field and Working Principle of XC6123E640ER-G </h3><p>XC6123E640ER-G is a highly integrated and intelligent power management IC (PMIC) designed for microcontroller and processor systems. It belongs to the PMIC - Supervisors family and has been designed with a focus on low quiescent current and high integration. The core of the chip is a supervisor circuit that can monitor the supply voltage and detect any drop or surge in it. It is also used to provide a reset signal when the main voltage supply goes down or rises above certain preset levels.</p><h4>Functional Features </h4><p>The XC6123E640ER-G integrates multiple monitoring, power supply, and power sequencing functions. This includes dual channels of adjustable over-voltage/under-voltage detector and one adjustable overcurrent/short-circuit detector. It also integrates a high-speed power supply sequencing controller with a maximum of 4 voltage steps. The chip is equipped with low-power I²C, SPI and simple SMBus to enable automotive-grade communication with external controllers. With the chip’s built-in LDOs and DC/DC converters, it can provide up to 3.3V core supply, 6V analog supply, and 3.3V digital supply.</p><h4>Working Principle </h4><p>The XC6123E640ER-G uses a comparator circuit to monitor the input supply voltage. An internal resistor divider sets a preset voltage level, and any voltage above or below this will cause the comparator to trip and give a reset signal. The reset signal is then used to control the power sequencing logic, which will switch off the power to the load if the voltage supply falls below a certain preset voltage level. The chip is also capable of detecting overcurrent and over-voltage faults, and can provide an output reset signal for protection.</p><h4>Application Field</h4><p>The XC6123E640ER-G provides an integrated solution for microcontroller and processor systems, with its deep level of integration, low quiescent current, and fast response timers. Its dual-channel voltage and current monitoring, power sequencing, and reset enable it to be a ideal choice for battery-powered systems and embedded systems, as well as automotive, industrial, and consumer applications.</p>
