The XC6121C644ER-G is a device that falls under Power Management Integrated Circuits category, specifically its subcategory called Supervisors. This specific device is a supervisor product that features an outstanding combination of multiple features such as under-voltage detection, over-voltage detection, delay time generator, an error flag, and manual reset. It is designed with CMOS technology and contained in a SSOP-8 package.Typically, the XC6121C644ER-G can be used for systems with complex power-up and power-down sequencing, providing a solution to all the power-on reset (POR) functions. As a supervisor, the device is designed with a configurable on-delay and off-delay time and error flag time, allowing for customization for both functions, as well as dual delay time selection and adjustable accuracy for manual reset timing.The main application field of the XC6121C644ER-G can be seen in systems that require an advanced power-down and power-up sequencing. This includes, but is not limited to, devices that utilize many voltage regulators, display interface power ICs, RS-232 and other interface ICs. In general, due to its low current and low power consumption during normal operation, the XC6121C644ER-G is ideal for battery-powered products such as smartphones, tablets, and laptops.In terms of its working principle, the XC6121C644ER-G supervisor acts as reliable and anti-fogging POR for the systems. It monitors multiple output voltages, over- and under-voltage conditions, to provide the appropriate reset signal and delay time generator for those output voltages. The device contains four input POR power supply pins (VIN1, VIN2, VIN3 and VIN4) that allow each input’s on/off delay to be adjusted. The device also features an on-delay timer, an off-delay timer, an error flag timer and a manual reset button. The on-delay timer determines the duration between the moment when the power supply’s voltage falls below VOUT1 and the moment when the reset signal comes up to 0. The off-delay timer determines the duration between the moment when the voltage of the power supply or the supplied voltage falls below VOUT1 and the moment when the reset signal comes up to 1. The error flag timer determines the timer\'s duration after the over-voltage or under-voltage error occurs. The manual reset button serves as an external reset switch that resets the device whenever pressed. All these elements, in combination with its CMOS technology and configurable parameters, allow the XC6121C644ER-G to serve its purpose as a reliable and robust supervisor that provides reliable reset signals, delay times, and low power consumption. To summarize, the XC6121C644ER-G is a device that belongs to the category called Power Management Integrated Circuits and its subcategory called Supervisors. It is mainly used for complex power-up and power-down sequencing and provides a solution to all the power-on reset (POR) functions. The device features an on-delay timer, an off-delay timer, an error flag timer and a manual reset button that work together to provide the appropriate reset signals and delay times. Moreover, due to its low current and low power consumption, the XC6121C644ER-G is an ideal option for battery-powered products.
