Hi, We are designing device where we need to recognize the charger type, but also we need to handle communication with the slave device. The question is if the internal switches of MAX14576 are open or close when: GOOD_BAT is high, VBUS is valid, D+/D- lines impedances do not correspond to: DCP, CDP, SDP or other specified in datasheet. Should I interpret the marked note as follows "if there is no standard recognized, it is set to SDP after DCD timeout"? Regards, Pawel

Hi,

We are designing device where we need to recognize the charger type, but also we need to handle communication with the slave device. The question is if the internal switches of MAX14576 are open or close when:

GOOD_BAT is high,
VBUS is valid,
D+/D- lines impedances do not correspond to: DCP, CDP, SDP or other specified in datasheet.

Should I interpret the marked note as follows "if there is no standard recognized, it is set to SDP after DCD timeout"?

Regards,

Pawel
