Power Management Integrated Circuits (PMICs) are a group of integrated circuits specially designed to convert and manage power in an electronic system. PMICs can include a variety of specialized ICs that include voltage regulators, power sequencers, buck, boost and buck-boost converters, plus a wide variety of other circuits.Supervisors are a type of PMIC that are designed to provide safe start-up, fail-safe shut down, monitoring and other control functions to ensure reliable system performance. Supervisors can monitor a variety of system parameters including input voltages, on/off status of components, current and real time system activity, and reset conditions. Supervisors can be integrated with other types of ICs such as voltage regulators and sequencers, or stand alone devices.The XC6123A519ER-G is a low-voltage, high-precision supervisor intended for use in battery-powered applications. It is designed to monitor multiple voltages and output a reset or interrupts signal to the microprocessor or other host during abnormal conditions.The XC6123A519ER-G’s alarm voltage range is adjustable and has an input voltage range of 0.9V to 6V. The reset output signal thresholds can also be configured depending on the application. The maximum output current is ±300mA with a temporal accuracy of ±2% across the entire temperature range of -40°C to +125°C.The XC6123A519ER-G is designed to provide a powerful signal to the microprocessor to protect it from self power-on reset and prevent system start-up failure during a power cycle. It also monitors the battery voltage and helps protect from overvoltage and overcurrent conditions, safeguarding the sensitive components from being damaged.The XC6123A519ER-G is widely used in various battery powered products such as mobile phones, laptops, portable media players, digital cameras and other handheld devices. It is also suitable for use in automotive and industrial applications. The XC6123A519ER-G has a low shutdown current and low operating current, making it ideal for applications that require low power consumption. In addition, the device has an I2C interface that allows visibility of device status through a simple read command.The working principle of the XC6123A519ER-G is based on voltage monitoring, current monitoring, and system reset and alarms. The device monitors the application’s power supply, system activity, and sets reset and alarm thresholds to ensure reliable system performance. When an abnormal event occurs, such as a power cycle or an overvoltage or undervoltage condition, the device will output a reset or interrupt signal to the microprocessor, providing the necessary safety features to make sure that the system is protected from catastrophic damage.In summary, the XC6123A519ER-G is a low-voltage, high-precision supervisor that is used for a variety of battery powered applications. It features low power consumption, adjustable alarm thresholds, I2C interface, and reset/interrupt functions. The wide range of features makes it suitable for a variety of applications including mobile phones, laptops, automotive and industrial applications.
