Hi All,
Is there any one familiar with USB2.0 and BC1.2 spec.?
Device connection detection requires device to pull up 1.5K Ohms resistor, but won't this conflict with BC1.2 charger type handshake electrical characteristics?
BC1.2 requires PD to force a 0.6V at DP when doing handshaking. But the device should be pulled up at DP or DM depending on speed of device per USB2.0 spec.
Won't these signal levels meet contentions when doing charging type handshaking?
Thanks for all your inputs.
