ON Semiconductor’s NCP5104 is a 600V gate driver which provides two outputs to directly drive two N-channel power MOSFETs or IGBTs arranged in a half-bridge configuration. It is ideal for use in the half-bridge motor-drive circuits that commonly power the motors in drones, safely handling transient over-voltage events up to 600V.

The device uses the bootstrap technique to ensure that the high-side power switch is properly driven. Operating from a 3.3V or 5V input, the NCP5104 may be controlled directly by a microcontroller.

• 50V/ns dV/dt immunity
• Gate-drive supply range: 10V-20V
• Output source/sink current capability: 250mA/500mA
• Matched propagation delays between both channels
