supply voltage (3.3 V); it is recommended to connect a decoupling
capacitor of 0.01 µF
H_OC2
E10
overcurrent sense input for downstream port 2; both the digital and
analog overcurrent inputs can be used for port 2, depending on the
hardware mode register setting; when not in use, it is recommended to
connect this pin to the VDD_5V pin
H_OC1

I
overcurrent sensing input for downstream port 1; both the digital and
analog overcurrent inputs can be used for port 1, depending on the
hardware mode register setting; when not in use, it is recommended to
connect this pin to the VDD_5V pin
