描述 Description

The STK57FU394AG-E is a fully-integrated PFC and inverter power stage consisting of a high-voltage driver, six motor drive IGBTs, one PFC IGBT, one PFC rectifier and a thermistor, suitable for driving permanent magnet synchronous (PMSM) motors, brushless-DC (BLDC) motors and AC asynchronous motors. The IGBTs are configured in a 3-phase bridge with separate emitter connections for the lower legs for maximum flexibility in the choice of control algorithm. An internal comparator and reference connected to the over-current protection circuit allows the designer to set individual over-current protection levels for the PFC and the inverter stages. Additionally, the power stage has a full range of protection functions including crossconduction protection, external shutdown and under-voltage lockout functions.

簡介

STK57FU394AG-E屬于集成電路（IC）的全半橋驅(qū)動器。由制造生產(chǎn)的STK57FU394AG-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)電機或無刷電機）所需的較大功率信號。
