The NCP5181 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 driver works with 2 independent inputs to accommodate any topology (including half−bridge, asymmetrical half−bridge, active clamp and full−bridge…).
