TPS2111APWRG4

The Texas Instruments TPS2111APWRG4 is a low-side switch specifically designed to provide integrated power-on reset (POR) and reliable power distribution for system administration and DSP/microcontroller reset. This integrated IC power distribution switch offers superior reset precision, layout flexibility, and convenience, making it a great addition to any system.

TPS2111APWRG4 Belongs to PMIC - OR Controllers, Ideal Diodes category of devices. This device is an ideal solution for applications where reset is critical, such as embedded systems, digital signal processors (DSPs), and microcontrollers. The device features integrated fast protection from overvoltage and current protection, along with a power-on reset (POR) function with active-high and active-low compartments without the need for additional external components.

The device provides a flexible reset function with an adjustable time-out period. It provides up to eight reset thresholds, adjustable over a range of voltages, to ensure proper system operation in different conditions. The device also has a built-in UVLO (Under Voltage Lock-Out) to ensure that the system is not damaged in the event of a sudden power drop. The device has an adjustable current limit to prevent power surges, and a version with thermal shutdown is also available.

The reset function of the TPS2111APWRG4 is activated by the power supply voltage level supplied to the VIN_RESET pin. Upon reaching the threshold voltage, the reset controller assert the reset output pin, causing the system to reset. The reset output is active for the duration of the adjustable time-out period and then inactive until the reset voltage is reached again.

The ideal diode capability of the TPS2111APWRG4 is able to route power from the system power supply to the load, even in the presence of reverse common-mode voltages. The device integrates a dual-channel ideal diode which provides protection from reverse voltages, thereby reducing the number of components required for protection, and enabling a higher power-to-feature ratio as well as greater system robustness and reliability.

The device is capable of operating over a wide input voltage range, between 2.5 V and 5.5 V, with a maximum switching frequency of up to 500 kHz. It is available in a TSSOP-16 package and a space-saving WQFN package, making it suitable for applications in which space is at a premium.

In summary, the TPS2111APWRG4 power distribution switch is an ideal solution for applications requiring integrated power-on reset (POR) and reliable power distribution. With features such as an adjustable reset time-out period, an adjustable current limit, and integrated ideal diode protection, the device offers great flexibility and convenience for efficient networking and accurate system control.
