The TPS2052BDRBT is a power distribution switch and load driver integrated circuit that is commonly used in the embedded system space. It is the main component of power management integrated circuit (PMIC) systems, providing system power distribution, load control, and detect and protection voltage regulation. Its application field and working principle is detailed below.

Application Field

The TPS2052BDRBT is a highly configurable and flexible solution for low/mid power system design applications. It is particularly suited for space-constrained embedded systems that require a wide input voltage range (3.3V to 24V) and offers excellent dynamic and static power dissipation. It is therefore popular in the industrial, automotive, communications, consumer and medical electronics markets.

The TPS2052BDRBT integrates two independent power supply paths, an H-Bridge and an inverted-L bridge, to provide reliable and reduced switching times in multiple voltage regime loads. Moreover, its capabilities include overvoltage, undervoltage, overcurrent, and thermal protection for the power wire and providing a robust design for power distribution.

Working Principle

The TPS2052BDRBT, as a power distribution switch and load driver works in three modes, namely as a low voltage regulator, as a high voltage regulator and as a power switch. In the low voltage regulation mode, the device regulates incoming voltage and distributes power through the H-Bridge and the inverted-L bridge, thereby minimizing static power dissipation. In the high voltage regulation mode, the TPS2052BDRBT adjusts the output current to prevent undershoot or overshoot of the output voltage.

In the power switch mode, the TPS2052BDRBT switches power distribution to the load components. The device has a built-in thermal sensor that monitors the device temperature and shuts-off the switching power path when the temperature is too high. It also helps in obtaining a dynamic current limit ion the load.

In addition to the three modes, the TPS2052BDRBT provides detection, protection and control via a variety of fault reporting and control outputs like over current detection, over voltage detection and under voltage detection. The integrated power control loop helps in maintaining the system parameters when switching between different working modes.

Conclusion

The TPS2052BDRBT is a highly configurable and efficient power distribution switch and load driver for embedded system application. Its three modes—low voltage regulator, high voltage regulator, and power switch—enable efficient operation in multiple voltage regimes and provide overvoltage, undervoltage, overcurrent and thermal protection to the power lines. Moreover, its integrated fault reporting and control help in maintaining the system parameters while switching between different working modes.
