PMIC - Supervisors are devices that are mainly used for embedded systems to efficiently manage and monitor the entire system power supply, as well as to detect failures in the operating system and shut it down. The TPS3808G15QDBVRQ1 is an excellent example of a supervisor device.

Applications
The TPS3808G15QDBVRQ1 is mainly used to monitor and control the power of large and complex embedded systems. It is designed to work with Real-time Operating System (RTOS) and Non-Real Time Operating System (non-RTOS) including ARM, Intel and 8051. Its monitoring functions include overvoltage protection, undervoltage monitoring, thermal shutdown and detection of power supply sequencing errors, providing a comprehensive safety system for all kinds of embedded systems. It is also an ideal device for battery management systems (BMS) and automotive applications due to its wide input voltage range, low operating current and small size.

Working Principle
The working of the TPS3808G15QDBVRQ1 is based on two different concept, triggered mode and monitor mode. In the monitor mode, the device continuously observes the system voltage, and in case of voltage overshoot and undershoot, it will sent a reset signal to the connected microcontroller. Further, upon detecting a system failure it will take trigger action to ensure a safe shutdown of the system. In the triggered mode, the user can initiate monitoring through push buttons, reset pulses from an external source, analog signals or digital signals.

Apart from this, the proficiency of the TPS3808G15QDBVRQ1 is not just limited to power monitoring. It also comes packed with versatile and user-friendly features such as adjustable rising and falling thresholds, pre-warning and reset delay times, 16-levels power sequencing configuration, 2-level extrinsic fault protection and multi-level intrusion detections. All these features are provided for the end user or the system integrator to design and implement a safe, low power, and eco-friendly digital system.

To summarize, the TPS3808G15QDBVRQ1 is an advanced supervisor device that uses a combination of triggered and monitoring modes to ensure maximum safety and efficiency of the power supply of embedded systems. It is an excellent choice for many industries as it offers excellent features, compatibility and reliability at a competitive price.
