operation.
The VP and VM pins are single-ended receiver outputs of the DP and DM pins,
respectively.
The DP (data plus) and DM (data minus) pins implement the USB data signals. When in
transparent general-purpose buffer mode, the ISP1301 operates as a level shifter
between the (DAT/VP, SE0/VM) and (DP, DM) pins.
The ID (identification) pin is connected to the ID pin on the USB mini receptacle. An
internal pull-up resistor (to VREG3V3) is connected to this pin. When bit ID_PULLDOWN
is set, the ID pin will be shorted to ground.
This pin acts as an input to the V
When the VBUS_DRV bit of the OTG Control register is asserted, the ISP1301 tries to
drive V
8 mA.
This pin is an input and supplies power to the ISP1301. The ISP1301 operates when V
is between 2.7 V and 4.5 V.
The C1 and C2 pins are to connect the flying capacitor of the charge pump. The output
current capacity of the charge pump depends on the value of the capacitor. For maximum
efficiency, place capacitors as close as possible to the pins.
