i our Motor Control Board with FOC i have very high losses in the Driver IC L6230Q in the VFQFPN package.
In the On-Time of the High side i have a differenz of 2.6V between the Operatine Voltage (21V) and the Output Voltage on the Motorphase. (see picture)
Channel 2 (blue) = Opperating Voltage
Channel 1 (yellow) = Out 2
measured direktly on the pins of the L230
One of the other Phase is Low (Low-Side On) and the third one is Open (EN is low)
With the thermo camera i can see hot points (>100°C) in the chip. so there is no bad soldering.
The schematic is equal to the datasheet.
With the P-Nucleo IHM001 i dont have this high losses. On this Board the L6230Q is in the big PowerSO36 Package
