Hello,
My name is Hidetoshi Matsunami.
I would like to ask you the following question;
The operation of TS3USB221 when Vcc isn't input.
I understand the input of D+/D- isn't output to 1D+/1D- or 2D+/2D- when Vcc is no input.
Is my understanding correct?
This charge pump circuit can't operate if Vcc isn't input.
Therefore, the driver which control a switch between A and B under the following figure is operated by charge pump circuit.
As a result, the driver can't operate and turn off the switch.
Best Regards
Hidetoshi Matsunami
