Working Principles

The TPS2831PWPG4 operates as a high-side power switch, controlling the flow of current to the load. When the enable pin (EN) is high, the switch is turned on, allowing current to pass through from the input (IN) to the output (OUT). The low on-resistance ensures minimal power loss during operation. In case of overcurrent or excessive temperature, the device automatically shuts down to protect the load and itself.
