NCx51705 EliteSiC MOSFET Gate Driver
onsemi single 6 A high-speed driver can deliver the maximum allowable gate voltage to a EliteSiC MOSFET device
onsemi NCx51705 low-side, single 6 A high-speed driver is designed to primarily drive EliteSiC MOSFET transistors. To achieve the lowest possible conduction losses, the driver can deliver the maximum allowable gate voltage to the EliteSiC 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 NCx51705 can utilize its on-board charge pump to generate a user-selectable negative voltage rail. For isolated applications, the NCx51705 also provides an externally accessible 5 V rail to power the secondary side of digital or high-speed optoisolators.
