The TPS3813J25DBVRG4 is a supervised voltage monitoring device from the family of Power Management Integrated Circuits (PMICs) produced by Texas Instruments Inc. The device is used for monitoring power supply voltages for microcontrollers, Digital Signal Processors (DSPs) and other integrated circuits. The TPS3813 monitors the power supply voltage and when the voltage drops below a predefined level the TPS3813 outputs an active high reset signal. This reset signal is used to reset the circuit and prevent unexpected operation or damage due to a low power supply voltage.The TPS3813J25DBVRG4 is a 4-pin voltage supervisor with an integrated voltage reference and a comparator circuit. The device operates with a maximum operating voltage of 6.5 V and provides a low current active-high output signal. The device has an overload protection circuit which prevents the output signal from staying high during overload conditions.The TPS3813J25DBVRG4 comes in the 8-SOIC package and has a fixed reset threshold of 2.5 V. The device is used in applications that require the power supply voltage to be monitored continuously so that the system can reset the circuit when there is an unexpected drop in the voltage due to a fault or a malfunction.The device also has an auto-retry functionality that automatically retries the reset signal after a predefined time if the voltage does not reach the reset threshold. This prevents the system from entering an unstable state due to a false reset signal. The device also has an input hysteresis control which helps to reduce the false triggering of the reset signal due to noise or ripple on the power supply voltage.The TPS3813J25DBVRG4 is ideal for embedded applications such as automotive, medical, industrial and consumer applications where accuracy, robustness and reliability are required in the power supply voltage monitoring function.In summary, the TPS3813J25DBVRG4 is a 4-pin voltage supervisor which works with a maximum operating voltage of 6.5 V. Its reset threshold is set at 2.5 V and it comes with an overload protection circuit and an auto-retry functionality. The device is used in a variety of applications where reliable power supply voltage monitoring is required and its input hysteresis control prevents false triggering of the reset signal.
