PMIC - Supervisors are an important type of integrated circuit that comes in various forms and offers various solutions for the protection and testing of circuits. In this article, we will look at the TPS3103K33DBVR application field and working principles.

The TPS3103K33DBVR is a voltage supervisor IC which is used to assure that the conditions of the system match the voltage levels that have been programmed. It allows for the detection of low voltage, overvoltage, power-down and power-up conditions, in addition to providing a mean for monitoring power-supply integrity and reset. This IC is suitable for use in many different applications such as computer motherboards, embedded systems, and communications devices. The supervisor IC and its application areas are described as follows:

The TPS3103K33DBVR voltage supervisor is designed to work as a single-channel device, with a low-voltage threshold that has been adjustable by the user. It is designed to detect and report various voltage fluctuations, including overvoltage and undershoots, and also reporting power-down and power-up conditions. This IC can also be used as a power-supply monitor to detect any changes in the input voltage or current, allowing the user to reset or halt the system if needed. It has a low-voltage output of up to 4.0V, which can then be used to drive other types of logic.

In terms of its working principles, the TPS3103K33DBVR supervisor IC is able to detect and report various voltage fluctuations, thanks to its on-chip comparator circuit. The comparator is triggered when the voltage supplied to the IC reaches the pre-programmed level and is able to measure voltage levels accurately up to ±50mV. The integrated circuit then sends out an appropriate signal to signify any overvoltage or undershoots, which can then be used to reset or protect the system.

In addition, this IC also has a power-down pin which is used to detect when the power-supply to the system is lost or gone under-voltage, which can be used to reset the system or protect it from further damage. In terms of power-up protection, the supervisor IC is able to detect when the power supply is restored, and therefore can be used to reset the system in order to start it up again safely.

In conclusion, the TPS3103K33DBVR is a voltage supervisor IC which is designed to report power-down, power-up, and various other voltage fluctuations. It can be used in numerous applications, such as embedded systems, motherboards and communications devices, thanks to its accurate detection of voltage levels and on-chip comparator. The power-down pin on the IC can be used for protection against power-loss, and the power-up pin is able to detect when the power supply is restored. Overall, the TPS3103K33DBVR voltage supervisor IC is an excellent choice for those who need reliable and accurate reporting of fluctuating or unsafe voltage conditions.
