Power management integrated circuits, also known as PMICs, are specialised integrated circuits used for controlling and managing the power of electronic systems. PMICs are widely used in electronic devices such as smartphones, laptops and tablets, as well as smaller scenarios such as IoT and wearables. PMICs greatly improve the efficiency of power management by controlling power utilization, maximising battery life and minimising energy wastage. There are numerous types of PMICs available, such as those used for voltage regulators, battery chargers, DC-DC converters, and so on. One type of PMIC is the supervisor, which is used to monitor the supply voltage of a system and provide reset signals to protect against undesired conditions such as overvoltage and dynamic surges. The TPS3851G50SQDRBRQ1 is a PMIC supervisor used in a variety of applications.

An important feature of the TPS3851G50SQDRBRQ1 is its high-accuracy voltage monitoring. It is designed to provide a reset signal when the supply voltage exceeds a preset threshold. This can help protect against damage from unexpected voltage excursions, and improve the reliability of the system. It also has an adjustable reset threshold that can be set from 1.22V to 5V, allowing it to adapt to various voltage ranges. In addition, it has an active-high reset output for easy interfacing with a wide range of system designs.

The TPS3851G50SQDRBRQ1 also features low-power operation, with a maximum quiescent current of 0.5uA. This helps ensure efficient power management, meaning the supervisor draws minimal power when not actually monitoring or resetting the system. This makes it suitable for use in low-power or battery-powered designs, where power efficiency is paramount.

The TPS3851G50SQDRBRQ1 application field is wide-ranging, with the device being used for various embedded systems and applications. It is typically used for robust system monitoring in industrial and automotive applications, such as in motor control, embedded systems, intelligent systems, and so on. Furthermore, it is also applicable in battery management systems, where it can ensure accurate and reliable protection against over-discharge.

The TPS3851G50SQDRBRQ1 works by monitoring the supply voltage of the system. It has three comparators, which are used to compare the target voltage against the actual voltage of the system. If the voltage differs significantly from the target voltage, then a reset signal is sent to the system. This reset signal is active-high, meaning that the system will reset itself if the voltage exceeds a certain threshold.

In short, the TPS3851G50SQDRBRQ1 is an excellent choice for PMIC supervisors, with its high-accuracy voltage monitoring, adjustable reset threshold and low quiescent current. It is used for multiple applications, ranging from industrial and automotive designs to battery management systems. The device can help to protect against unexpected voltage excursions by providing a reset signal when the voltage exceeds a certain threshold.
