Power Management Integrated Circuit (PMIC) provides a complete power solution to the host system. It consists of multiple power stages, including power Conversion, power Distribution, current & voltage regulation, over current protection, etc. Among them, Hot Swap Controllers such as LM25061PMMX-2/NOPB is used to protect the internal circuitry of the host system from sudden current surges.

The LM25061PMMX-2/NOPB is a Hot Swap Controller from Texas Instruments. It includes an Under Voltage Lockout (UVLO) circuit that prevents the output currents from exceeded specified levels during increase or decrease of loads to the systems. It features both current cut-off and overload protections to protect the internal circuits from overload and short circuit conditions. Additionally, it includes hardware circuit speed when turning off the output stage, reducing heat generated. Overall, this chip offers a wide variety of features for effective system protection.

The working principle of LM25061PMMX-2/NOPB is that it uses an internal voltage divider to accurately detect and adjust the output voltage. The output stage is controlled by an N-Channel MOSFET, and the power stage is functional when the output of the voltage divider is greater than 0.5V. When the output voltage exceeds an over voltage threshold level, the voltage divider output become lower than 0.5V, and the output stage is cutoff to prevent over voltage damage. When the output voltage is lower than a predetermined under voltage, the divider output is greater than 0.5v, and the power stage is enabled again.

The LM25061PMMX-2/NOPB is widely used in a variety of applications, both digital and analog. It is used in digital ICs, such as ASICs and FPGAs, for hot swappability and protection. It is also used in analog ICs, such as power amplifiers and audio converters, to achieve high performance while maintaining safety and reliability. Moreover, it is often employed in a wide range of portable devices, like GPS, mobile phones, medical equipment, and more.

In conclusion, the LM25061PMMX-2/NOPB is a reliable and efficient Hot Swap Controller from Texas Instruments. It has many features and functions that makes it suitable for a range of applications, from general-purpose system protection to power amplifiers. And its voltage divider-based control system provides accurate and reliable overvoltage and undervoltage protection that ensure system safety. To sum up, the LM25061PMMX-2/NOPB is a versatile and dependable solution for power management in modern electronics and applications.
