Working Principles

The VNQ05XSP16 is a power driver IC that combines a power MOSFET with CMOS logic circuitry. It operates by receiving control signals (IN1 and IN2) to drive the internal power MOSFET, which in turn controls the output current to the load connected to the OUT pin. The device is powered by the VCC supply voltage and can be enabled or disabled using the EN pin. Diagnostic information is provided through the DIAG pin.
