Allegro公司的SX68000M是高压三相马达驱动器,可以控制三相全桥电路,额定功率为250V/2A,500V/1.5A或500V/2.5A.驱动器集成了掩护功能如UVLO,OCP,热关断(TSD)以及限流(OCL)和预驱动器等.主要用在小型马达控制如空调风扇和白色家电冷却风扇.本京电港论坛文章先容了SX68000M主要特点和优势以及典范应用电路原理图纸. High Voltage 3-Phase Motor Drivers The SX68000M series provides the solution for controlling 3-phase full bridges that utilize MOSFETs rated at 250 V/2 A, 500 V/1.5 A, or 500 V/2.5 A. The IC includes in a single package: protection functions such as UVLO (protection circuit for controlling power supply voltage drop), OCP (overcurrent protection), TSD (thermal shutdown), and OCL (current limiting), and a pre-driver with ¯ F¯O¯ (Fault Output) terminal and bootstrap diodes with limit resistors. The SX68000M series is packaged in a fully-molded SOP with 27 pins at 1.2 mm pitch. Body size: 22 × 14.1 × 2.1 mm. SX68000M主要特点和优势: ▪ Built-in bootstrap diodes with limit resistors ▪ Built-in protection circuit for controlling power supply voltage drop (UVLO) ▪ Built-in Thermal Shutdown (TSD) ▪ Built-in Current Limiter (OCL) ▪ 7.5 V regulated output SX68000M应用: ▪ Small motor control: ▫ Air conditioning fan ▫ White goods cooling fans |
