Hi BU expert,
Can the no-load and loaded status of TPS2546 be judged by the high and low levels of PIN 9 STATUS? When TPS2546 is no-load, PIN 9 is high level, and when TPS2546 is discharging, PIN 9 is low level, right?
Are DM_IN and DM_OUT connected when TPS2546 is powered on? Are DP_IN and DP_OUT directly connected?
If the power is not turned on, then DM_IN and DM_OUT are not connected? DP_IN and DP_OUT are not connected?
Regards,
Charlie
Hi Charlie,

The Status register depends on the CTL and ILIM settings and is not just dependent on the loading.
Are DM_IN and DM_OUT connected when TPS2546 is powered on? Are DP_IN and DP_OUT directly connected?
Data line connection also depends on the control GPIOs. Initially, the lines should not be connected, the TPS2546 will check for the far end connection type and determine connection between the pins dependent on the table.
If the power is not turned on, then DM_IN and DM_OUT are not connected? DP_IN and DP_OUT are not connected?
There is no connection when there is not power.
Thanks and Regards,
Chris
