NSI6622B-DSPNR

The NSI6622B-DSPNR is an isolated dual-channel gate driver from Novosense - a power-device driver, not a digital isolator - for MOSFET, IGBT and SiC stages in motor drives, solar inverters, server power and industrial supplies. The SOP-16 narrow-body (SP) ordering code provides 3.0 kVRMS isolation, with 700 VRMS working voltage, 990 Vpeak repetitive peak voltage, more than 4 mm creepage and clearance, and a comparative tracking index above 600, which supports reinforced-insulation system designs at moderate cost. The B version sets undervoltage lockout at 8 V typical (the A and C versions are 6 V and 13 V), so confirm the UVLO variant matches your power device's gate threshold before ordering. The part is rated from -40 C to +125 C with MSL 1 handling. Selection advice: the three UVLO variants exist precisely because a wrong lockout level either nuisance-trips a high-threshold SiC stage or under-protects a logic-level MOSFET; state the full ordering code, including the B suffix, in your RFQ so the correct variant is quoted.
