Working Principles

The BTS4880RAUMA1 operates as a high-side power switch by controlling the flow of current to the load. It uses input control signals (IN1 and IN2) to turn the switch on or off. When the control signals are activated, the IC allows current to flow from the positive supply voltage (Vbb) to the load through the output pins (OUT). The IC incorporates various protection mechanisms such as overtemperature, short-circuit, and overload protection to ensure safe and reliable operation.
