BTS7751G集成電路（IC）的全半橋驅(qū)動(dòng)器規(guī)格書(shū)PDF中文資料

BTS7751G屬于集成電路（IC）的全半橋驅(qū)動(dòng)器。由英飛凌科技股份公司制造生產(chǎn)的BTS7751G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(chēng)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(lèi)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)。

Description

The BTS 7751 G is part of the TrilithIC family containing three dies in one package:

One double high-side switch and two low-side switches. The drains of these three vertical DMOS chips are mounted on separated lead frames. The sources are connected to individual pins, so the BTS 7751 G can be used in H-bridge- as well as in any other configuration. Both the double high-side and the two low-side switches of the BTS 7751 G are manufactured in SMART SIPMOS? technology which combines low RDS ON vertical DMOS power stages with CMOS control circuitry. The high-side switch is fully protected and contains the control and diagnosis circuitry. Also the low-side switches are fully protected, the equivalent standard product is the BSP 78.

In contrast to the BTS 7750 G, the BTS 7751 G offers an open load in Off-mode detection and slightly increased current limitation.
