TPS6598x Barrel Jack Detection

Intellectual 1120 points

Hi,

 

The customer is asking about Barrel Jack Detection (High or Low Input based on GPIO event) on how we can TPS65982EVM to become source or sink.

 

Based on the GPIO Events on TPS6598x Firmware User’s Guide Section 13-2 Table 13-1,

 

The problem now is on EVM, regardless “Barrel Jack Detect” is high or low, it is always sink. This is not correct as per GPIO event as above.

Is there configuration settings need to make this work?

 

How do we make or ensure that when “Barrel Jack Detect” is high, the voltage on VBUS CANNOT pass back to the Barrel jack?

 

Thanks.

 

Best regards,

Gim Song
