说明

ISO5851 是一款用于 IGBT 和 MOSFET 的 5.7 kVRMS 增强型隔离栅极驱动器,具有 2.5A 的拉电流能力和 5A 的灌电流能力。输入端由 3V 至 5.5V 的单电源供电运行。输出侧支持的电源电压范围为 15V 至 30V。两路互补 CMOS 输入控制栅极驱动器输出状态。76ns 的短暂传播时间保证了对于输出级的精确控制。

内置的去饱和 (DESAT) 故障检测功能可识别 IGBT 何时处于过载状态。当检测到 DESAT 时,栅极驱动器输出会被拉低为 VEE2 电势,从而将 IGBT 立即关断。

当发生去饱和故障时,器件会通过隔离隔栅发送故障信号,以将输入端的 FLT 输出拉为低电平并阻断隔离器的输入。FLT 的输出状态将被锁存,可通过 RST 输入上的低电平有效脉冲复位。
