Isolated gate drivers feature UVLO

They are in stock at authorised distributor DigiKey.

Single or split outputs support 3 V to 20 V input and up to 30 V gate drive. Using Skyworks silicon isolation, they provide 6 kV_RMS isolation, high noise immunity, low delays, and better reliability than optocouplers.

The voltage-mode output allows optimized switching performance, while built-in protections like undervoltage lockout (UVLO) and input overlap protection ensure safe operation.

The Si82Bx and Si82Ex are isolated gate drive solutions for power switch driving needs, including silicon MOSFET, IGBT, SiC, and GaN.

These devices support 3 V to 20 V input and up to 30 V gate drive. This includes proven voltage mode gate drive architectures with a variety of CMOS inputs with deglitch options, single channel with combined or split output configuration, integrated Miller clamp, and assorted UVLOs according to the power switch type being driven.

With outstanding isolation ratings of up to 6 kV and compliance with VDE 60747-17, AEC-Q100 qualifications and automotive-grade options, and a variety of popular packaging options, this device family is suitable for isolated gate drive needs.

The Si82Cx and Si82Fx high-performance isolated gate drivers offer solutions for power switch driving needs, including silicon MOSFET, IGBT, SiC, and GaN. These devices include the revolutionary SelVCD current mode architecture with a variety of CMOS inputs with deglitch options, single channel with split output configuration, and assorted UVLOs suitable for the power switch type being driven.

Applications cover AC/DC power supplies, DC/DC converters, Onboard chargers (OBC), Servo motor drive, AC induction motor drive, Solar PV/UPS inverters, Large AC induction motor drive, Large PV/UPS inverters, and traction inverters.

These gate drivers are available from DigiKey in the EMEA, Americas and Asia/Pacific regions.
