TPS2543: Connect/Disconnect Detection?

Part Number: TPS2543

Hi team,

I have questions about TPS2543. Could you support?

Setup:

 D+, D-: Pulled-up by MCU when device is connected. will be low when device will disconnected.

 CTL(1-3): 111 = CDP Mode

1. I can see re-connection process as CDP Mode when disconnect -> connect CDP device on EVM. Does this mean TPS2543 can hand-shake automatically when device will be connected?

2. Does TPS2543 have a function of connect/disconnect detection?

3. Is there any other condition that TPS2543 will be hand-shake automatically?

Regards,

Kotaro Yamashita

    Hello Kotaro,

    Please see answers to your questions below.

    1. Yes, the TPS2543 does automatic handshaking when connected to a portable device

    2. The STATUS pin (pin 9) is an active-low open-drain output, asserted in load detection conditions

    3. Anytime a device is connected, or the advertising mode of the TPS2543 is changed, the TPS2543 will automatically hand-shake with the connected device.
