供应高压桥臂驱动器/FAN7382
信息内容：高压桥臂驱动器飞兆半导体的FAN7382 另一个让紧凑、低成本的模块能够成为现实，从而彻底变革马达驱动器的新技术，是高压(600V)桥臂驱动器。现代高压桥臂门极驱动器，如飞兆半导体的FAN7382，采用先进的设计减小了高压IC工艺中寄生的源漏电容，从而使驱动器具有足够的稳健性，能承受-9V以上的负电压。这种驱动器优于上一代驱动器相比的地方是，电源电压的正负尖刺不会造成驱动器闭锁和控制信号丢失。而且，匹配传输延迟在50ns以下，使到开关频率可达100kHz或150kHz。 这种IC内增加的共模dV/dt噪声消除电路还有助于减少误导通的可能性，因而提高电源电路的稳健性并使芯片更加紧凑，且无需额外的滤波器元件。这类IC(如FAN 7382)的静态电流较小，故工作温度也较低，从而提高可靠性。采用该技术，可以去掉上几代马达驱动器中非常普遍采用的4个隔离电源，同时在微控制器PCB板与功率开关PCB 板之间也无需光隔离，带来了板面空间和成本的节省。 The FAN7382, a monolithic half-bridge gate driver IC, can drive MOSFETs and IGBTs that operate up to +600V. Fairchild's high-voltage process and common-mode noise canceling technique provides stable operation of the ...
