PMIC (Power Management ICs), or Power Management Integrated Circuits, are integrated circuits that allow efficient regulation and management of the power in a wide range of electronic devices such as laptops, cell phones, and cameras. The TPS259521DSGT is a PMIC comprised of a hot swap controller. A hot swap controller facilitates the safe and reliable operation of high-powered systems such as servers and other computers.

TPS259521DSGT Application Field

The TPS259521DSGT PMIC series features hot swap controllers that are specifically designed to be used in high-power load applications such as datacenter servers and high power computing. This series of hot swap controllers is part of a larger suite of Power Management products from Texas Instruments.

The TPS259521DSGT PMIC series is designed to protect systems from damage caused by unexpected loads and surges of current. The main feature of this series of PMICs is the ability to “hot swap” components in and out of high-power systems without needing to power down the system. This hot-swap feature is particularly useful in datacenters, where replacing components needs to be done quickly and efficiently.

The TPS259521DSGT PMIC series also features overcurrent and overtemperature protection, which helps protect systems from damage caused by high current and heat. Additionally, the TPS259521DSGT PMICs are designed to maintain a constant voltage to the system and protect against significant voltage droops. These features help ensure the longevity and reliability of high-power systems.

TPS259521DSGT Working Principle

The TPS259521DSGT PMICs feature a variety of hot-swap controllers that use hysteretic control to allow insertion and removal of components in high-power systems without interrupting power to the system. Hysteretic voltage control involves the system measuring the voltage level, and then automatically adjusting it to the desired level.

The TPS259521DSGT PMICs feature a monitoring circuit, which helps detect faults such as overtemperature or overcurrent. The monitoring circuit allows for a safe power sequence when inserting or removing components from the system. This power sequence helps ensure a reliable operation of the system and prevents damage from occurring.

The TPS259521DSGT PMICs are also designed with an on-chip supervisor IC, which provides a range of protection functions such as overcurrent protection and undervoltage lockout. This supervisor IC ensures that the system is operating safely, even when unexpected changes occur in the system.

Conclusion

The TPS259521DSGT PMICs are designed to be used in high-power load applications such as datacenters and computers. The main feature of these PMICs is the ability to safely hot-swap components without interrupting the power to the systems. The TPS259521DSGT PMICs feature a variety of protection mechanisms such as overcurrent protection and overtemperature protection, which help ensure the safety and reliability of the system. The TPS259521DSGT PMICs also feature a power sequence mechanism and a supervisor IC, which helps provide a safe and reliable operation of the system.
