Product Description

The MP86885 is a monolithic half-bridge with built-in internal power MOSFETs and gate drivers. It achieves 40A of continuous output current over a wide input supply range. Integration of the driver and MOSFETS results in high efficiency due to optimal dead time control and parasitic inductance reduction. The MP86885 is a Monolithic IC approach to drive up to 40A per phase. This very small 4mm x 6mm FC-TQFN device can operate from 100kHz to 1MHz. This device works with tri-state output controllers. It also comes with a general-purpose current sense and temperature sense. The MP86885 is ideal for server applications where efficiency and small size are a premium.
