Hello,
We’re presently running our TLE9180D31 3-phase bridge at 20kHz PWM frequency and would want to increase it but there’s no specification in the device datasheet for this parameter, is there any specification or application information anywhere differently about this parameter or is this an Infineon apps engineer question?
Thanks,
Hi @Adrianbyrne, The maximum frequency depends on your external MOSFET, so this isn't a restriction for our device. The TLE9180D is typically designed for a maximum total gate charge of 300nC per output stage (20kHz). If PWM frequency, However, total gate charge or number of driver MOSFETs increasesRead more
Hi adrianbyrne,
See lessThe maximum frequency depends on your external MOSFET, so this isn’t a restriction for our device.
The TLE9180D is typically designed for a maximum total gate charge of 300nC per output stage (20kHz).
If PWM frequency, However, total gate charge or number of driver MOSFETs increases, it’s recommended to use a booster IC, for example: AUIRS08152S.
