Tool/software:
The DRV8412 datasheet states "up to 2 x 3A continuous output current (2 x 6A peak) in dual full bridge mode" but the pulsed peak current per output pin (Io_pulse is 15A).
My interpretation of this is that the board can withstand 15A per output pin without sustaining damage, but it will quickly enter an overtemperature shutdown at such a high output current. Therefore, the thermal performance limits the DRV8412 to 2x6A peak. Is that correct? Does TI have any test data on how long the DRV8412 can sustain 2 x 6A? Possibly on the eval board.
