TAS5342LA Overcurrent adjust resisor value

We want to know the MAX current according to OC-adjust register value 27kOhm.

Because we can refer 27kOhm as OC-adjust register value from typical application schematics on the datasheet.

Figure 14/Figure 15/Figure 17/Figure 18

Do you have an answer?

Hello,

Currently we do not have a specification on the current with 27K OC-adjust resistor.

However, with OC-adjust = 22K the typical current limit is 8.4A and the minimum is 7.9A.

Best Regards,

Matt

Hi Matt

Thank you for you reply.
I understand we should refer the description on the table in datasheet (22kohm/33kohm/47kohm).

So, we think it is better to have changed the 27kohm resister shown in the several figures on the datasheet.
