NCV81341P
Automotive Dual DrMOS
with Integrated Current
and Temperature Sense
NCV81341, NCV81341P
The NCV81341/P (NCV81341 – Single Phase and Two
Independent Phases Mode, NCV81341P – Parallel Mode) integrates
two MOSFET drivers, highside MOSFET and lowside MOSFET
into a single package with current sense and temperature monitoring
into a compact 3.5x3.5 QFN.
The driver and MOSFETs have been optimized for highcurrent
DCDC buck power conversion applications. The NCV81341/P
integrated solution greatly reduces package parasitics and board space
compared to a discrete component solution.
