Switching frequency100-1000 kHz
Output 11.2 V / 55 A
IC revision1.02

Description

The MP86884 is a monolithic half-bridge with built-in internal power MOSFETs and gate drivers. It achieves 55A 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 MP86884 is a Monolithic IC approach to drive up to 55A per phase. This very small 6mmx6mm TQFN device can operate from 100kHz to 1MHz.This device works with tri-state output controllers. It also comes with a generalpurpose current sense and temperature sense.The MP86884 is ideal for server applications where efficiency and small size are a premium.
