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.
