描述 Description

The MP86961 is a monolithic Half Bridge with built-in internal power MOSFETs and gate driver. It achieves 20A continuous output current over a wide input supply range.
Integrating the Driver and MOSFETs results in high efficiency due to optimal dead time control and parasitic inductance reduction.
The MP86961 is a Monolithic IC designed to drive up to 20A per phase. Housed in a very small 5x5mm QFN Packge, this device can be operated from 100kHz to 1MHz.
The IC is intended to work with 5V tri-state output controllers.
The MP86961 is ideal for notebook applications where efficiency and small size are a premium.

簡(jiǎn)介

MP86961屬于集成電路（IC）的全半橋驅(qū)動(dòng)器。由制造生產(chǎn)的MP86961全半橋驅(qū)動(dòng)器器件屬于電橋驅(qū)動(dòng)器電源管理集成電路 (PMIC) 系列，包含兩個(gè)或多個(gè)功率晶體管，以及在外部器件控制下將其用作開(kāi)關(guān)所需的電路。這些晶體管通常在內(nèi)部配置為成對(duì)串聯(lián)連接（稱為半橋），因而任意指定晶體管對(duì)之間的結(jié)點(diǎn)都可以連接至兩個(gè)電源軌中的任一個(gè)。這類器件常用于將控制器件（如微控制器）提供的低電平信號(hào)轉(zhuǎn)換為操作執(zhí)行器（如步進(jìn)電機(jī)或無(wú)刷電機(jī)）所需的較大功率信號(hào)。
