pulses. The internal circuitry is powered via the input pin. During normal operation the Input is connected to the
Gate of the power MOSFET. During fault condition the device sinks the current
back to the driving circuit. The current handling capability of the driving circuit does not influence the device
behavior as long as the supply current
