TPS3831A09DQNR

The TPS3831A09DQNR is a low-power precision under-voltage monitoring supervisor integrated circuit with fixed and adjustable threshold voltage. It boasts several key features: high accuracy and low power over temperature and supply voltage, an open-drain flag indicating the status of an input voltage and user-selectable power-on reset delay. This device is ideal for monitoring under-voltage and over-voltage conditions in systems such as computers, servers and communication systems.

TPS3831A09DQNR belongs to the Power Management Integrated Circuits (PMIC) supervisors family, as it monitors and reports voltage levels. PMIC supervisors are specialized components responsible for system-level optimization and total power management of the entire system. Its primary functions are to detect when the system power supply drops below a predetermined threshold and to issue an alert signal.

The TPS3831A09DQNR is a highly accurate voltage supervisor designed for under-voltage, over-voltage and tamper conditions. It has an adjustable threshold voltage range from 0.11V to 2.83V with a tolerance of 0.8%. This range of voltages is suitable for different applications, such as system power-on reset and power-supply monitoring. Additionally, it includes both an open-drain flag and a power-on reset delay function, both of which provide an indication of the current status of the system.

The TPS3831A09DQNR features a low-power consumption, making it suitable for large and small systems. It consumes just 120nA at 3V and 0.3uA at 4.5V, which is significantly lower than other supervisory solutions. In addition, it can operate from -40°C up to +85°C ranges, making it suitable for a wide range of industrial and consumer applications.

The TPS3831A09DQNR is a simple and versatile voltage supervisor device. Its integrated functions, high accuracy and low-power consumption make it an ideal solution for any application that requires monitoring of power supply voltages.

In summary, the TPS3831A09DQNR is an excellent PMIC supervisor device that is suitable for any application requiring power supply monitoring. It has both high accuracy and low power consumption, making it an ideal solution for applications where system reliability and accuracy are paramount.
