Working Principles
The BTS5441G operates as a high-side power switch by controlling the flow of current from the supply voltage (VS) to the load connected to the OUT pin. It utilizes a MOSFET as the switching element and incorporates various protection features to ensure safe operation in automotive systems.
When the input signal (IN) is applied, the enable pin (EN) activates the power switch, allowing current to flow from VS to the load. The integrated protection circuitry monitors parameters such as temperature, voltage, and current to prevent damage to the load or the IC itself. Diagnostic feedback signals provide information about the status of the power switch.
