Other Parts Discussed in Thread: DRV8873,
Hi
Would like to know the capabilities for the DRV8873 IC.
We have the possibility to obtain a ECU with about 6 of these ICs inside. This number of IC are not used for any vehicle in this setup, but if we want we can populate them on the circuit board to use them.
But the question is then what the current capabilities is for this particular IC is. The ambient temperature for this IC can be 95℃
I know there is alot depending on the cooling, thus the connection to the PCB. But lets assume there is sufficient number of vias and that the aluminium casing is connected to the back of the PCB to cool it.
What would be the highest constant RMS current capable for this IC? (lets say the IC is connected to the inductive load (Rmax=2ohm) in full bridge ). VinMax=14v VinMin=10v
Output PWM would be 10kHz or 20kHz
Also, is there a pin compatible version of this IC that can handle higher power?
What do you think about the possibilities to sync 2 of these ICs to have a multiphase converter driving the same inductive output load? But thus sharing the load between 2 of these ICs?
guess you will have lots of questions, so feel free to ask them. See this as a first initial contact.
