A PMIC - Supervisors is a type of integrated circuit that monitors the various voltages in a digital system and ensures that the system works according to its design specifications. The TPS389050GQDSERQ1 is a voltage supervisor from Texas Instruments that offers a wide range of features and benefits. It is used in a variety of applications including microprocessors, power management systems, embedded systems, and embedded communications. This article will discuss the application fields and working principles of the TPS389050GQDSERQ1.

The TPS389050GQDSERQ1 is able to precisely monitor voltages in a wide range of operating supply voltages. It is specifically designed to protect microprocessor-based systems from fault conditions such as overvoltage, undervoltage, an open load, or an overcurrent condition. The device is able to monitor two distinct voltages, the main supply voltage and an auxiliary supply voltage. Additionally, the TPS389050GQDSERQ1 has built-in automated protection features that are able to provide a high level of safety and reliability.

When it comes to application fields, the TPS389050GQDSERQ1 is suitable for use in digital power management systems, embedded systems, and embedded communications. It is also suited for use with microprocessors that require precise voltage monitoring. The device offers a handy reset function and can be used to monitor a wide range of digital systems, from single-core to multi-core microprocessor and power management systems. For embedded systems, the TPS389050GQDSERQ1 can help to contain transient overvoltages, ensuring maximum system stability. In addition, it can protect a system from damage during periods of power failure and restore operation in the event of a fault.

The working principle of the TPS389050GQDSERQ1 is based around a comparator circuit. The comparator compares the monitored voltages to a preset threshold voltage and then triggers a push-pull output state in the event of a fault. The output state is determined by the action of the preset trip levels and is used to indicate a fault and reset the system. The device is also capable of generating an active-low interrupt signal that can be used to notify the processor of a fault condition.

The TPS389050GQDSERQ1 offers a great solution for monitoring digital power systems, embedded systems, and embedded communications. It is able to monitor voltages with a high level of accuracy and offers automated protection features to ensure reliable operation. Additionally, its reset and interrupt configurations provide a great range of features for maximizing system safety. This PMIC - Supervisors is a great choice for effectively protecting digital systems from fault conditions.
