NCP5181
High Voltage High and Low
Side Driver
The NCP5181 is a High Voltage Power MOSFET Driver providing
two outputs for direct drive of 2 Nchannel power MOSFETs arranged
in a halfbridge (or any other highside + lowside) configuration.
It uses the bootstrap technique to insure a proper drive of the
Highside power switch. The driver works with 2 independent inputs
to accommodate any topology (including halfbridge, asymmetrical
halfbridge, active clamp and fullbridge
).
