MP86945A
Intelli-PhaseTM Solution with Integrated
High-Side and Low-Side FETs and Driver
DESCRIPTION
The MP86945A is a monolithic half-bridge with
built-in, internal power MOSFETs and gate
drivers. The MP86945A achieves 60A of
continuous output current over a wide input
supply range.
The MP86945A is a monolithic IC approach that
drives up to 60A of current per phase. The
integration of drivers and MOSFETs results in
high efficiency due to optimal dead time and
parasitic inductance reduction. The MP86945A
can operate from 100kHz to 2MHz.
The MP86945A offers many features to simplify
system design. The MP86945A works with
controllers with tri-state PWM signal and comes
with an accurate current sense to monitor
inductor current and temperature sense to
report junction temperature.
The MP86945A is ideal for server applications
where efficiency and small size are a premium.
