PMIC (Power Management Integrated Circuits) Supervisors are specialized microcontrollers that are used to manage power supply sequencing and power-on reset (POR) applications. The TPS3847085DBVT is a Power Management Integrated Circuit (PMIC) Supervisors sub-category. It is specially designed for applications like smartphones, tablets, PCs, industrial equipment and automotive solutions.

The TPS3847085DBVT allows the user to monitor supply voltage levels and track system power states in order to protect the device from improper or dangerous power conditions. It is a compact, cost-effective and highly integrated supervisor with low power. In contrast to many conventional solutions, TPS3847085DBVT integrates a voltage reference, power-on reset circuit, reset comparators, logic levels, and external load capacitors.

Applications of TPS3847085DBVT
The TPS3847085DBVT PMIC Supervisors provide Supply Voltage Monitor (SVM) and Power-on Reset (PoR) functions to protect and reset systems from improper or dangerous power conditions that may occur in Automotive, Industrial, and mobile applications. It can also be used in smartphones, tablets, PCs, servers, automotive, industrial and mobile applications which require reliable power monitoring and power sequencing. It is also suitable for applications where high levels of integration, accurate voltage monitoring, reset, and system sequencing is required.

Working Principle of TPS3847085DBVT
The TPS3847085DBVT PMIC Supervisors provide power on reset (PoR) and supply voltage monitoring (SVM) functions. The device utilizes the external capacitance and resistor value to generate the reset and supply compare output. The PoR circuit uses an internal reference voltage and the external resistor and capacitor values to create an accurate reset trip point. The voltage comparator circuit ofSVM can detect the voltage levels, which are important for quick detection and reset. It will only issue reset when the PoR and SVM compare levels have been met.

The device integrates logic levels to indicate the system power status and has an active low reset output to reset the system. The TPS3847085DBVT features reset pulse duration and detect latency, which are both adjustable using the external resistor and capacitor values. The device comes with an accuracy of 10K sampling rate, which is an industry standard. It also features an OCPGA pin which enables the device to maintain its accuracy while in sleep or other low power modes.

The TPS3847085DBVT PMIC Supervisors also feature an adjustable power-on reset threshold voltage with a maximum voltage of -2.6V. The device is protected against reversed supply conditions, input failure, output over-current, and output over-voltage. Additionally, it is protected from falsely triggering of reset due to voltage glitches, cold startup, board vibrations, etc.

The TPS3847085DBVT is a low power PMIC Supervisors device, suitable for many different power related applications. Its low power consumption, accurate detect and reset functions, and adjustable Vcc/Vdd thresholds make it more attractive. Its wide operating temperature range and high reliability make it suitable for industrial and automotive applications. Its accuracy and the 10K sampling rate make it highly effective in a number of applications.
