The NSi66x2 series of highly reliable isolated dual-channel gate driver ICs from Novosense Microelectronics can be designed to drive power transistors with switching frequency up to 2MHz.

They are available from distributor Ineltek

Each output can source and sink up to 4A/6A with fast propagation delay of 25ns and the maximum delay matching of 5ns. All parts are rated for an operation from -40°C up to +125°C. Depending on the package - 5*5mm LGA13: 2500Vrms; SOIC16 (150mil): 3000Vrms and SOP14/SOP16 (300mil): 5700Vrms - different isolation voltages are achieved for 1 minute according UL1577.

CQC certification GB4943.1-2011, CSA certification with components for 5A qualified and VDE certification DIN V VDE V 0884-11:2017-1 are available.

The minimum common mode transient immunity (CMTI) of 100kV/µs (typ. 150kV/µs) improves system robustness. The maximum supply voltage of the driver is 30V (recommended 25V), and the input side the recommended supply voltage is 3V to 5V.

All supply voltage pins (input & output side) support undervoltage lockout (UVLO).

There are three classes of UVLO available (6V, 8V, 12V). With all these features, NSi66x2 fits in applications which require high reliability, high power density and high efficiency.
