Working Principles

The TPS2553QDBVRQ1 operates as a power distribution switch by controlling the flow of current from the input source to the load. When the enable pin (EN) is activated, the switch allows current to pass from the input pin (IN) to the output pin (OUT). If an overcurrent condition occurs, the device limits the current to protect the load and other components. Additionally, the thermal shutdown mechanism safeguards against excessive heat, ensuring the longevity of the switch.
