Product Summary

The NCP5181DR2G is a High Voltage Power MOSFET Driver providing two outputs for direct drive of 2 N-channel power MOSFETs arranged in a half-bridge (or any other high-side + low-side)configuration. It uses the bootstrap technique to insure a proper drive of the High-side power switch. The applications of the NCP5181DR2G include: (1)High Power Energy Management; (2)Half-bridge Power Converters; (3)Any Complementary Drive Converters (asymmetrical half-bridge active clamp); (4)Full-bridge Converters; (5)Bridge Inverters for UPS Systems.
