2U3824-50QDBVRG4Q1

PMIC supervisors are a family of circuits that monitor power conditions on an electronic system. The 2U3824-50QDBVRG4Q1 is a particular PMIC supervisor from integrated circuit manufacturer STMicroelectronics. It is designed to monitor the battery voltage of mobile systems such as cellular phones and other portable products.

The 2U3824-50QDBVRG4Q1 is an enhanced PMIC supervisor, providing a variety of important features. It has an active-low reset output with a 10 μs assertion and 10 ms de-assertion time, as well as an adjustable threshold with a reset assertion voltage ranging from 2.2 V to 4.8 V. It also features an input voltage monitor for voltage protection, low power consumption and a low reset active current.

The primary application of the 2U3824-50QDBVRG4Q1 is to monitor the voltage of a system\'s li-ion battery and to assert a reset signal when the battery drops below a certain level. This helps improve system reliability by providing a failsafe when the battery voltage drops too low. In addition, the PMIC supervisor can also be used to monitor other power conditions, such as notification of an AC power loss event.

The 2U3824-50QDBVRG4Q1 PMIC supervisor operates by continuously measuring the voltage of the monitored line. When the voltage reaches or goes below the reset assertion voltage, the 2U3824-50QDBVRG4Q1 will assert a reset signal. The reset signal is maintained until the monitored voltage reaches or goes above the reset de-assertion voltage.

In addition to its reset function, the 2U3824-50QDBVRG4Q1 also features an event notification for AC power loss, allowing the system to be paused or placed in power-save mode when the AC power is disconnected. This feature can be used to conserve battery power in a system that relies on external power.

The 2U3824-50QDBVRG4Q1 is an important device for ensuring reliable system operation, as it is designed to monitor power conditions and provide a failsafe when the battery voltage drops or when the AC power is disconnected. In addition, it provides a low power consumption solution with a reset assertion voltage that can be adjusted between 2.2 V and 4.8 V, making it an ideal solution for use in mobile and other low power systems.

Overall, the 2U3824-50QDBVRG4Q1 is a versatile PMIC supervisor that can be used to monitor power conditions and provide protection against low battery voltage or AC power disconnection. It is a highly reliable and low power solution that is suitable for use in a variety of mobile and portable systems.
