Hi Duncan,
DRV8432 is in PFB mode to drive a TEC upto 12A @ 24V.
Used the 24kohm resistor as OC_adj. It is referring Table:2 in datasheet the maximum current before overcurrent occurs is 10.7A.
Could you please explain what this 10.7A exactly. Whether on each channel is the max limiting current is 5.4A or 10.7A.
Referring to the link e2e.ti.com/.../133322
"As Paralleling the outputs are not directly tied together. A ferrite bead or inductor should be placed between each parallel connected output"
I am using Fixed inductor 4.7UH 13.5A 11.2 MOHM SMD (part no: ASPI-1367-4R7M-T). The inductor current rating is a power ferrite bead can be used instead of an inductor. The current rating is higher than the RMS current of the my system.
I am getting a nFault error for 6A current @ 15V only. Now DRV8432 is also died.
Thanks
Regards
