The TPS2111PWR is a subset of the Texas Instruments TPS211x family of integrated OR controllers that provide more efficient power distribution, reduce power dissipation, and enable higher performance in any given power management application. The family of OR controllers equipped with an integrated IDEAL diode feature helps enable the system to dynamically switch power to different loads. The TPS2111PWR provides an integrated ideal diode that replaces an external diode and Schottky rectifier, thus resulting in improved power efficiency.

The TPS2111PWR operates across a wide range of input voltages, making it suitable for portable applications that use a variety of DC power sources, such as batteries, solar cells, and AC adapters. It also offers other features that include power monitoring with two power-good (PG) pins, programmable soft start capability, over-voltage and under-voltage protection, and integrated PMOS and NPN transistor output drivers.

The TPS2111PWR\'s OR controller standouts in the TPS21X1 family through its highly efficient power distribution technology. This architecture makes use of a main channel ideal diode, which can feed power to multiple secondary channels. The main channel eliminates various inefficient power dissipation paths that an external diode would normally have. This makes the overall power management system much more efficient, with a power efficiency improvement over external diodes of up to 30%, depending on the application.

The TPS2111PWR is designed to support various power creation modes and power distribution modes in order to enhance the efficiency of the overall power management system. In the power creation mode, the device\'s OR controller enables two power sources—such as USB and adapter ports—to be connected in parallel to create an available voltage. This voltage can then be used to power multiple downstream devices.

In power distribution mode, the OR controller enables different downstream devices to receive varying levels of power, depending on their power demands. The device is able to detect the power demands of all the devices connected to it and switch the power sources accordingly, ensuring that each device receives the power it needs. This power distribution process occurs in a matter of milliseconds, ensuring the power supply is not disrupted and performances is smooth.

The TPS2111PWR also enables safe operation by providing integrated over-voltage (OV) and under-voltage (UV) protection, which help add a layer of protection to the power management system. The OV and UV protection thresholds can be set and adjusted as needed. The TPS2111PWR also provides two power-good (PG) pins, which allow for monitoring of the input voltage conditions. This helps ensure that the system is operating safely.

In summary, the TPS2111PWR is an efficient, reliable, and versatile OR controller, with integrated ideal diode, that provides enhanced power distribution, improved power efficiency, and improved performance in any given power management application. Thanks to its wide range of application fields and its versatile working principle, the TPS2111PWR is an ideal choice for any task requiring enhanced power management.
