PMIC - SupervisorsThe 2U3837K33QDBVRG4Q1 is a supervisor IC specially designed to provide system-level monitoring and protection for applications with high power requirements and high current density requirements. This IC is a highly robust and reliable device with versatile protection options and a wide range of operating conditions, enabling it to be used for a variety of industrial and consumer applications.The 2U3837K33QDBVRG4Q1 is an IC specifically designed to provide power supply protection and monitoring for applications with wide supply voltage ranges, high current requirements, and high frequency devices. It is an integrated device which consists of two independent voltage monitoring circuits and a protection circuit. The monitoring circuits allow the IC to detect and regulate input voltages from different sources in order to provide protection from power-inflicting surges, over-voltage and/or under-voltage. The protection circuit meanwhile provides a wide range of system-level over-voltage, over-current, and over-temperature protection.When the IC detects either an over-voltage or under-voltage event, it will trigger an internal logic signal or a reset signal to the system. The logic signal can be used to initiate a sequence of events, such as powering off certain supplies, resetting the system, or signaling warning screens to users.In addition to voltage monitoring and protection, the 2U3837K33QDBVRG4Q1 also provides system-level over-current, short-circuit, and reverse polarity protection features. Its integrated current-sensing circuit is able to detect current flow in different directions and its protection circuit can be configured to respond to either over-current or short-circuit events. Lastly, the integrated reverse polarity protection feature ensures that the IC will not be damaged if it is connected to the wrong power source.The 2U3837K33QDBVRG4Q1 is a highly reliable and versatile IC which is suitable for a wide range of industrial and consumer applications. It can provide robust system-level protection against over-voltage and under-voltage conditions as well as over-current, short-circuit, and reverse polarity events. Furthermore, its small size and low power requirements make it a great choice for embedded and portable applications.
