VN770集成電路（IC）的全半橋驅(qū)動器規(guī)格書PDF中文資料

VN770屬于集成電路（IC）的全半橋驅(qū)動器。由意法半導(dǎo)體集團制造生產(chǎn)的VN770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)電機或無刷電機）所需的較大功率信號。

DESCRIPTION

The VN770 is a device formed by three monolithic chips housed in a standard SO-28 package: a double high side and two Power MOSFETs. The double high side are made using STMicroelectronics VIPower technology; Power MOSFETs are made by using the new advanced strip lay-out technology. This device is suitable to drive a DC motor in a bridge configuration as well as to be used as a quad switch for any low voltage application. The dual high side switches have built-in thermal shut-down to protect the chip from over temperature and short circuit, status output to provide indication for open load in off and on state, overtemperature conditions and stuck-on to VCC.
