TPS2085DR is a power distribution switch, also known as a power switch. It is a part of the family of Power Management Integrated Circuits (PMICs) and can be used in many different applications. It is designed to switch power from one source to another and to provide over-voltage and over-current protection. In this article, we will look at the application field and working principle of the TPS2085DR.

Application Field

The TPS2085DR can be used in a wide range of applications. It can be used to power supply and battery manager circuits, USB power distribution systems, power supply and protection circuits, and any other system where a high-side switch is needed. With its built-in over-voltage and over-current protection, it can also be used as a part of an intelligent power management system.

Moreover, the TPS2085DR can be used in automotive applications, providing both power distribution and protection. It is programmable, meaning it can be used to switch power according to the specific needs of the application. It is especially well-suited for high-power applications, as it can handle up to 10A.

Working Principle

The TPS2085DR is a high-side power distribution switch, meaning it can be used to switch power from one source to another. The TPS2085DR works by having an internal power FET that is opened and closed through the use of a logic signal. This logic signal can be generated from an integrated controller or from an external signal source.

When the logic signal is present, the internal FET is turned on, allowing the power to be switched from one source to the other. The FET also has built-in protection, meaning that it can safely switch power in the presence of over-current and over-voltage conditions without damaging the device or the system.

The TPS2085DR also has a built-in EMI filter, which helps to reduce the amount of unwanted noise in the system. This filter helps to keep the power supply clean and safe to use in all types of applications.

Conclusion

The TPS2085DR is a high-side power distribution switch that can be used in a variety of applications. It has built-in protection, is programmable, and has an integrated EMI filter. It is especially well-suited for high-power applications, as it can handle up to 10A. With its wide range of features and applications, the TPS2085DR is a great choice for power distribution, switching, and protection.
