Power Management Integrated Circuit (PMIC) is a device which provides power management functions for a wide range of applications. It is used to control, monitor and regulate the power on the board, often from multiple sources. Supervisors are a specific type of PMICs which protect the system from unwanted conditions or events. Examples of such events include overvoltage, overtemperature, over-current, etc.The XC6121C533MR-G is one such supervisor, used to provide protection to circuits from unwanted events or conditions. It is a single-channel, TTL/CMOS Reset and Preemptive Reset supervisor co-developed by Xinaasonic and Nexperia Industries.The XC6121C533MR-G supervisor provides a wide range of functionality and features. It has a wide input voltage range of 1.7V to 6.5V and temperature range of -40°C to +85°C. It provides two precision voltage monitors, one Watchdog Timer (WDT) and one proven-safe overtemperature monitor (OTP). The XC6121C533MR-G has a wide reset threshold range and provides a reset output delay function (ROD) to prevent false reset during power-up. Moreover, it features a reset signal pre-emission and dual reset pre-emission posts, eliminating the need for additional reset signal generators.The XC6121C533MR-G supervisor is suitable for use in a wide range of applications. It is an ideal device for 12V bus systems and 3.3V DC-DC converter systems in mobile, automotive, industrial, and consumer applications. The various protection features such as overvoltage, overtemperature and over-current, make it suitable for use on computer motherboards. Its low active current and wide temperature range also make it ideal for industrial environments.The XC6121C533MR-G uses a combination of voltage, temperature and signal sensors to detect the circuit conditions. When an event occurs, it shuts off the connected device by asserting the reset signal. The reset signal can be extended by the ROD function. The WDT monitors the internal uptime counter and can be used to perform periodic tasks such as data logging or alarms. The OTP ensures that the maximum temperature is not exceeded and automatically shuts down the connected circuitry if so.In summary, the XC6121C533MR-G is a single-channel, TTL/CMOS Reset and Preemptive Reset supervisor co-developed by Xinaasonic and Nexperia Industries, suitable for use in a number of applications. It has a wide input voltage range, temperature range, reset threshold range and features like WDT and OTP. It is designed to provide protection from unwanted conditions and events and is ideal for applications such as mobile, automotive, industrial, and computer systems.
