Other Parts Discussed in Thread: DRV8305, , TMS320F28027F, CSD18531Q5A
With the chip shortages impacting our products we are trying to find a replacement MOSFET for CSD18540Q5B. We are using this in a circuit driven by the DRV8305 and the TMS320F28027F for sensorless driving of a brushless DC motor. The battery supplying power is 36-42V and the motor pulls a max of 15A.
I see similar parts CSD19502Q5BT, CSD18532NQ5BT, with slightly higher Gate-to-source threshold voltage. Going from 1.5-2.3V to 2.4-3.4V.
This is the only difference I can see that has a possibility of being problematic.
Would these suffice as replacements?
