MP86905
Intelli-PhaseTM Solution with
Integrated HS-/LS-FETs and Driver
DESCRIPTION
The MP86905 is a monolithic half-bridge with
built-in internal power MOSFETs and gate
drivers. The MP86905 achieves 50A of
continuous output current over a wide input
supply range.
The MP86905 is a monolithic IC approach to
drive up to 50A of current per-phase. The
integration of drivers and MOSFETs results in
high efficiency due to optimal dead time and
parasitic inductance reduction. The MP86905
can operate with a range from 100kHz to 2MHz.
The MP86905 offers many features to simplify
system design. The MP86905 works with
controllers with tri-state PWM signal and comes
with an accurate current sense to monitor the
inductor current and temperature sense to
report junction temperature.
The MP86905 is ideal for server applications
where efficiency and small size are a premium.
The MP86905 is available in a small FC-QFN
(4mmx4mm) package.
