MP8690屬于集成電路（IC）的全半橋驅(qū)動器。由美國芯源系統(tǒng)有限公司制造生產(chǎn)的MP8690全半橋驅(qū)動器器件屬于電橋驅(qū)動器電源管理集成電路 (PMIC) 系列，包含兩個或多個功率晶體管，以及在外部器件控制下將其用作開關(guān)所需的電路。這些晶體管通常在內(nèi)部配置為成對串聯(lián)連接（稱為半橋），因而任意指定晶體管對之間的結(jié)點(diǎn)都可以連接至兩個電源軌中的任一個。這類器件常用于將控制器件（如微控制器）提供的低電平信號轉(zhuǎn)換為操作執(zhí)行器（如步進(jìn)電機(jī)或無刷電機(jī)）所需的較大功率信號。

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.
