NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit
board with maintained transverse airflow greater than 500 lfpm. Electrical parameters are guaranteed only over the declared
operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification
limit values are applied individually under normal operating conditions and not valid simultaneously.
5. V_DD and V_sup have separated pads for noise and EMI immunity improvement – by similarity with the NCN6001 V_DD and V_sup have to be
equal and connected to the same power supply (V_DD = V_sup = V_DDPA/B)
6. Ceramic X7R, SMD type capacitors are mandatory to achieve the CRD_VCC ripple specifications. The ceramic capacitor has to be chosen
according to its ESR (very low ESR) and DC bias features. The capacitance value can strongly vary with the DC voltage applied (see Figure
22).
