PMIC (Power Management Integrated Circuits) is a type of integrated circuit that is used to manage power in a wide range of electronic devices. Supervisors are a specific type of PMICs that are designed to monitor the operating conditions of an electronic device, keeping it in working order and optimizing its performance. The TPS3808G01DBVR is a popular example of this type of IC and is used to provide overvoltage protection, reset and monitoring of the power supply. This article will discuss the application field and working principle of the TPS3808G01IDBVR Supervisory IC.

The TPS3808G01DBVR is used in a variety of applications, but it is primarily used in consumer electronics like digital cameras, smart phones, tablets, and audio systems as a way to regulate and monitor power supply voltages. It can also be used in industrial applications such as automated test equipment and instrumentation, where it provides protection against power surges and detects power-on or power-down events. This IC is also popular for use in automotive systems, providing voltage protection for electronic components.

At the heart of the TPS3808G01DBVR is a supervisor circuit that incorporates a few key components and works off of a 4 to 16-volt range. The overvoltage protection and reset can be easily triggered in the event of an overvoltage situation. To do this, the IC uses an N-Channel MOSFET switch that can be easily turned on and off. When turned on, it acts as a voltage comparator, detecting any voltage that is greater than a user-defined threshold. If the threshold is exceeded, the reset line is triggered and the MOSFET switch turns off.

The IC also incorporates a Watchdog timer and a few analog inputs to monitor and control the voltage of the power supply. The Watchdog timer can be set to an adjustable time period, usually between 4 and 16 seconds. During this time period, if the voltage remains within a user-defined range, it will be considered valid. If it goes outside the desired range, a reset signal is sent, which causes the MOSFET switch to shut off. This protects the system from potentially damaging voltage variations and can be used to shut down the system in case of a power failure.

The TPS3808G01DBVR also includes a few analog inputs that can be selected by the user. These allow the IC to monitor the power supply voltage and to be able to detect any variation in the voltage that is above a defined threshold. This helps the IC to keep the voltage within a specified range, preventing any potential damage due to overvoltage or undervoltage conditions.

Overall, the TPS3808G01DBVR is a highly effective Supervisory IC that provides reliable overvoltage protection and reset capability. It is versatile, suitable for a variety of applications and is easy to incorporate into power supply designs. It provides reliable protection against damaging voltage variations and can detect power failure situations. These features make the TPS3808G01DBVR an ideal choice for a wide range of applications.
