描述 Description

The STK5Q4U352J-E is a fully-integrated inverter power stage consisting of a high-voltage driver, six IGBT’s and a thermistor, suitable for driving permanent magnet synchronous (PMSM) motors, brushless-DC (BLDC) motors and AC asynchronous motors. The IGBT’s are configured in a 3-phase bridge with separate emitter connections for the lower legs for maximum flexibility in the choice of control algorithm.
The power stage has a full range of protection functions including cross-conduction protection, external shutdown and under-voltage lockout functions. An internal comparator and reference connected to the over-current protection circuit allows the designer to set the over-current protection level.

簡介

STK5Q4U352J-E屬于集成電路（IC）的全半橋驅動器。由制造生產(chǎn)的STK5Q4U352J-E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。
