描述 Description

This IC is a 3-phase inverter power hybrid IC containing power elements(IGBT and FRD), pre-driver, overcurrent and excessive temperature protection circuit.

特性 Features

? Integrates power elements(IGBT and FRD), pre-driver, and protective circuit.
? Protective circuits including overcurrent(bus line), excessive temperature and pre-drive low voltage protection are built in.
? Direct input of CMOS level control signals without an insulating circuit (photocoupler, etc) is possible.
? Single power supply drive is possible by using a bootstrap circuit with a built-in IC
? Temperature monitor is possible by the thermistor inside the IC
? Built-in simultaneous upper/lower ON prevention circuit to prevent arm shorting through simultaneous ON input for the upper and lower side transistors.(Dead time is required for preventing shorting due to switching delay.)
? SIP(The single in-line package) of the transfer full mold structure.

應(yīng)用 Application

? 3-phase inverter motor drive

簡(jiǎn)介

STK621-061-E屬于集成電路（IC）的全半橋驅(qū)動(dòng)器。由制造生產(chǎn)的STK621-061-E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)。
