PMIC (Power Management Integrated Circuit) is an important part of modern consumer electronics designs due to their ability to help regulate the power supply voltages, converting DC voltage supply to the AC voltage.Supervisors are PMICs which are used to detect when the power supply voltage falls below an acceptable level, signaling a potential problem that needs to be addressed. One of the most popular supervisors is the XC6121A216ERG, designed by XMCAR Corporation, which has been consistently used in designs for consumer electronics devices for many years.The XC6121A216ER-G is a low-power, low-cost three-terminal supervisory PMIC with an internal 0.8V fixed voltage threshold. It is designed to monitor the power supply voltage and provide an active-low RESET signal when the input voltage falls below the preset threshold. The RESET signal is open-drain, allowing it to be connected to an external pullup resistor, or OR\'d together with other RESET signals.The XC6121A216ER-G is available in 3.3V or 5V versions, and is rated for operation over a wide temperature range (-40°C to +85°C). It features an automatic power-down mode which significantly reduces the power consumption and extends battery life, making it ideal for battery-powered applications. It also offers a low reset threshold and tight supply voltage tolerance of ±0.2V, allowing it to accurately detect the microvoltage variations typically found in battery-operated devices.The XC6121A216ER-G is mostly used for mobile electronic devices such as cell phones, PDAs, and laptop computers. Its compact Quad Flat No-Lead (QFN) package allows it to be placed on the most challenging circuit boards. Its low supply voltage and current requirements make it ideal for monitoring low-power battery-powered circuits.In addition to being used in mobile electronics, the XC6121A216ER-G is also commonly used in automotive and industrial applications. The ability to accurately detect small voltage variations at low power supply makes it perfect for applications that involve controlled power down sequences or need to monitor precision voltage levels.When the XC6121A216ER-G is powered on, its internal comparator monitors the power supply voltage and compares it to the reference threshold value. When the input voltage is greater than the reference value, the RESET output is released to a high impedance state, enabling the connected device to properly reset itself and begin normal operation. However, if the supply voltage drops below the preset threshold, the RESET output will be driven low, indicating the need for an emergency shutdown.The XC6121A216ER-G can be used in combination with a variety of reset controllers, including watchdog and reset generators, to provide additional reset control. It can also be used to generate a reset signal on power up, detect power-on and power-off conditions, monitor short circuit events, and create an audible warning signal when the supply voltage dips too low.Overall, the XC6121A216ER-G is a versatile and economical PMIC supervisor, perfectly suited for applications involving low-power battery-powered circuits. Its built-in reset functions, along with its wide temperature range, make it a reliable choice for both consumer and industrial applications. With its small form factor, it can be easily used in designs requiring space-saving components, while its wide supply voltage range makes it suitable for a variety of applications. It truly encompasses a great combination of both performance and economy.
