TPS22810DRVR Application Field and Working Principle

TPS22810DRVR is a Power Management Integrated Circuit (PMIC) from Texas Instruments specially developed for power distribution, load drivers and LED lighting applications with integrated inrush current and active current limiting circuits.

Application Field

TPS22810DRVR is especially designed for applications where high current and voltage rails are switched, such as in data centers, wireless base stations, commercial, automotive and industrial automation systems.

The chip has a wide operating range of up to 28V and A current rating of 8A. It also has a variety of built-in protection features and adaptive thermal management, which makes it ideal for applications where reliability and safety are a priority.

The chip has excellent surge protection, short-circuit and overtemperature protection to provide maximum protection for switching circuit and load.

Working Principle

The TPS22810DRVR works by triggering the activation of an N-channel Field Effect Transistor (NFET) after a control signal is received. An NFET is like a gate that is opened and closed by a digital signal.

When the input signal is HIGH, the internal NFET is blocked, preventing current from flowing from the source to the load. When the input signal is LOW, the NFET turns ON, allowing current to flow through the load.

The TPS22810DRVR is designed to maximize power efficiency and minimize power losses. It has two selectable power saving modes that can be adjusted according to the load requirements.

The chip also has a built-in Active Current Limiting (ACL) circuit that prevents overloading of the system. When the load connected to the chip exceeds its peak current rating, the ACL circuit will limit the current and prevent damage to the load.

The chip has an integrated over-temperature protection circuit that prevents damage to the system by shutting down the NFET when the temperature rises above a certain level.

The chip also includes an Inrush Current Limiting (ICL) circuit that prevents the system from drawing excessive current during power-up or transient switching conditions.

Conclusion

The TPS22810DRVR is an innovative PMIC from Texas Instruments that has a wide range of applications for powering, controlling and protecting switch circuits and loads. It has a range of integrated safety features and a variety of output current and voltage ratings, making it the ideal choice for systems that require reliable and safe operation.
