绝缘体上硅(SOI)栅极驱动器
用于IGBT和MOSFET的绝缘体上硅(SOI)高压电平转换栅极驱动器
英飞凌绝缘体上硅(SOI)技术是一种高压的电平转换技术,具有许多独一无二和无与伦比的明显优势,包括集成自举二极管(BSD),以及业界一流的抗负瞬态电压尖峰的能力。每个晶体管都被埋入的二氧化硅隔开,从而可以有效避免易造成闩锁的寄生双极晶体管。该技术还可降低电平转换功率损耗,从而最大限度降低器件开关的功耗。这一先进工艺可打造出具有技术强化优势的单片式高压及低压电路 结构。
最新推出2ED218x - 高电流650 V,2.5 A半桥SOI栅极驱动器系列和2ED210x - 低电流650 V,0.7 A半桥 SOI栅极驱动器系列。两个产品系列均包含DSO-8和DSO-14封装选项。

面对VS引脚的负瞬态电压(-VS)的运行稳定性
如今的高功率开关逆变器及驱动都携带很大的负载电流。VS引脚上的电压摆动不会只停留在负直流母线的电平上;相反,因为功率器件中的寄生电感及PCB走线中的寄生电感,它会摆动到负直流母线的电平以下。
采用英飞凌SOI技术的EiceDRIVER™高压电平转换门极驱动芯片产品,拥有业界一流的运行稳定性。下图显示了VBS = 15 V和脉宽高达1000 ns时6ED2230S12T(即将发布)的安全运行线。在绿色区域内,产品不会出现功能异常,亦不会对集成电路造成永久性损害。
