VN5770AK-E集成電路（IC）的全半橋驅(qū)動器規(guī)格書PDF中文資料

VN5770AK-E屬于集成電路（IC）的全半橋驅(qū)動器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的VN5770AK-E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(jī)或無刷電機(jī)）所需的較大功率信號。

Description

The VN5770AK-E is a device formed by three monolithic chips housed in a standard SO-28 package: a double high side and two low side switches. The double high side is made using STMicroelectronics VIPower? M0-5 Technology, while the low side switches are fully protected VIPower? M0-3 OMNIFET II. 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.

Features

■ General features

– Inrush current management by active power limitation on the high side switches

– Very low stand-by current

– Very low electromagnetic susceptibility

– In compliance with the 2002/95/EC European directive

■ Protection

– High side drivers undervoltage shutdown

– Overvoltage clamp

– Output current limitation

– High and low side overtemperature shutdown

– Short circuit protection

– ESD protection

■ Diagnostic functions

– Proportional load current sense

– Thermal shutdown indication on both the high and low side switches

Applications

■ DC motor driving in full or half bridge configuration

■ All types of resistive, inductive and capacitive loads
