Working Principles

The AUIPS2051L operates as a high-side switch, controlling the flow of current from the battery to the load. When the control input (IN) is activated, the switch turns on, allowing current to flow from the battery (VBAT) to the load (OUT). The device continuously monitors the current and voltage levels, providing protection against overcurrent and overvoltage conditions. In case of excessive current or voltage, the AUIPS2051L quickly shuts off the switch to prevent damage to the load or the device itself.
