NCP51705

Single 6 A High-Speed,

Low-Side SiC MOSFET

Driver

The NCP51705 driver is designed to primarily drive SiC MOSFET

transistors. To achieve the lowest possible conduction losses, the

driver is capable to deliver the maximum allowable gate voltage to the

SiC MOSFET device. By providing high peak current during turn−on

and turn−off, switching losses are also minimized. For improved

reliability, dV/dt immunity and even faster turn−off, the NCP51705

can utilize its on−board charge pump to generate a user selectable

negative voltage rail.

For full compatibility and to minimize the complexity of the bias

solution in isolated gate drive applications the NCP51705 also

provides an externally accessible 5 V rail to power the secondary side

of digital or high speed opto isolators.
