Product 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.
