Infineon 1ED44175N01B 5kW单路低边IGBT栅极驱动器解决方案

Infineon公司的1ED44175N01B是低压功率IGBT非反向栅极驱动器,逻辑输入和标准CMOS或LSTTL输出兼容,输出驱动器具有电流缓冲器级.1ED44175N01B具有用于过流检测的引脚和FAULT状态输出(激活时,EN/FLT引脚内部拉低).EN/FLT需要外部拉高以提供正常工作,拉低EN/FLT禁用驱动器.VCC引脚的内部电路提供欠压锁住保护,保持输出低电平直到Vcc电源电压在工作范围内.器件具有-0.246V过流阈值,精度为±5% .器件具有过流检测和负电压输入,可编故障清除时间,CMOS施密特触发器输入,3.3V,5V和15V输入逻辑兼容,支持25V VCC电源电压(最大), 3 kV ESD HBM , RoHS兼容.主要用在住址空调,马达,系统控制和监视以及大功率开关电源.本文介绍了1ED44175N01B主要特性,框图和应用电路,以及采用IKW40N65WR5, IDW60C65D1和1ED441755kW的5kW两路交错CCM PFC评估板EVAL-PFC5KIKWWR5SYS主要特性和指标,框图,电路图,材料清单和PCB设计图.

The 1ED44175N01B is a low-voltage, power IGBT, non-inverting gate driver. Proprietary latch-up immune CMOS technologies enable ruggedized monolithic construction. The logic input is compatible with standard CMOS or LSTTL output. The output driver features a current buffer stage. The 1ED44175N01B has OCP pin for over current protection sense and a FAULT status output (when activivated, EN/FLT pin is internally pulled down). The EN/FLT needs to be externally pulled up to provide normal operation, pulling EN/FLT low disable the driver. Internal circuitry on VCC pin provides an under voltage lockout protection that holds output low until Vcc supply voltage is within operating range.
