Product 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.
