VN770集成電路（IC）的全半橋驅動器規(guī)格書PDF中文資料

VN770屬于集成電路（IC）的全半橋驅動器。由意法半導體集團制造生產(chǎn)的VN770全半橋驅動器器件屬于電橋驅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換為操作執(zhí)行器（如步進電機或無刷電機）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.
