DRV8714-Q1: EM and ECM effect on adjacent pins

Masaru Oinaga

Part Number: DRV8714-Q1

Tool/software:

Hello, Team,

We are asked about how TI thinks about how an electromigration (EM) and electrochecmical migration (ECM) would affect below motor drivers in terms of a pin spacing:

DRV8143PQDGQRQ1
DRV8145PQPWPRQ1
DRV8714SQPHPRQ1
DRV8106HQRHBRQ1

Especially, GL1 and GND1 (and other gate driving pins & GND pins) of DRV8714-Q1 is placed adjacent and doesn't EM/ECM need to be taken care?

Best Regards,
Masaru

Hi Masaru,

At the IC level this is accounted for with our recommended specs and IC level testing that we perform that stressed the part. Is there a concern on the customer side. Can you tell me who is the customer and their application? If they really want more detail I recommend requesting a PPAP if they have a NDA with us.
