bq24160 / Duration of D+/D- detection

Other Parts Discussed in Thread: BQ24160

Hi Team,

Now our customer is evaluating bq24160 with bq27530. Then they hope to know the duration of D+/D- detection. They need to know this duration because they need to define the duration that bq27530 need to stay by completing D+/D- detection.

Per page 21, after USB is above UVLO, D+/D- is attempted for 500ms. If not completed by then, the default current limit is 100mA.

Hi Jeff-san,

Thank you for your comments. As stated in P21 in datasheet, I'll recommend our customer to wait for 500msec after D+, D- lines are connected with assuming worst situation.

Best Regards,

Sonoki
