The TPS3851H30SQDRBRQ1 is a low-voltage power supervisor available from Texas Instruments (TI). It is used to provide timing and reset signals in systems where a reset is required when the power supply voltage falls below a certain level. The device is part of TI\'s Power Management IC (PMIC) family, specifically a type of supervisor device that monitors the power supply and sends a reset signal in the event of a fault. This device is an optimized version of the TPS3851 and offers a smaller footprint while providing the same functionality.

The TPS3851H30SQDRBRQ1 is a highly integrated and shielded power supervisor that offers both single resistor and low-voltage detect (LVD) functions. The single resistor function is used to initiate a reset when the power supply voltage drops below a certain level. The LVD function is used to detect a low-voltage fault such as over-voltage, under voltage, or brown-out conditions. The device also has an active-high reset output that is used to reset the system in the event of any of these conditions.

The device features a wide range of voltage thresholds, from 1.260V to 4.6V, allowing it to be used with a variety of different power supplies. It has an active low-voltage detect output and a watchdog timer output for indication and system reset. Inputs to the device can be either analog or digital, allowing for greater flexibility with the source of the monitoring signal.

The TPS3851H30SQDRBRQ1 is a very low-power device, typically consuming only 1.8 mW while active and 0.2 mW while in standby. This makes the device suitable for any application where power-efficient operation is required. The device is also housed in a small 6 pin TSSOP package, making it suitable for use in space-critical applications. It is qualified for use in automotive, industrial, and military applications, as well as being suitable for consumer electronics applications.

The primary application field for the TPS3851H30SQDRBRQ1 is as a power supervisor in electronic systems. In its most basic form, the device is used to detect the power supply status of a system and to provide the necessary reset signal if the voltage falls below the set threshold. In addition, the device can be used for timing functions, with its watchdog timer providing an accurate, deterministic timing signal for system reset.

In conclusion, the TPS3851H30SQDRBRQ1 from TI is one of the most efficient power supervisors available on the market. It provides a comprehensive power management solution while still being able to fit into the tightest of spaces. With its wide range of threshold settings and its active low output, the device can be easily integrated into any system, offering reliable and accurate power management.
