Figure 7. Typical Application System with USB Transceiver
In a condition where D+ and D- are shorted when a
charger is plugged into the USB port, the USB switch is
ON and pulled to VDD, which is about 3.3 V, making both
D+ and D- HIGH and flag1 set HIGH – indicating that a
charging device is connected to the port.
With USB Transceiver (Figure 7)
The FAN3988 sets the FLAG1 pin to logic HIGH or
LOW as an indicator to the system controller that a
standard USB device or a charger is connected to the
USB port. The FAN3988 also monitors the VBUS for
over- or under-voltage conditions. The FLAG2 pin is set
LOW if VBUS is less than 3.3 V or greater than 6.0 V.
In a condition where D+ and D- are connected to a
standard USB device, the D+ is pulled to VDD and D- is
set LOW (due to the 15 kΩ pull-down in the USB
transceiver) and flag1 is LOW.
In a standard USB configuration, there is a switch in the
USB transceiver that is always ON in the full-speed
mode. It is ON during the transition from full-speed
mode to high-speed mode and is turned off after
enumeration is complete.
If D+ and D- are open (floating), D+ is pulled to VDD and
D- floats LOW, which makes flag1 LOW.

When a condition exists where a charger is plugged into
the USB port (D+ D- shorted), the voltage divider of
1 MΩ and 5 MΩ puts a voltage of 2.75 V on the D+ D-
inputs and flag1 is HIGH, indicating a charger is
connected to port.
Without USB Transceiver (Figure 8)
The FAN3988 sets the FLAG1 pin to logic HIGH or
LOW as an indicator to the system controller that a
standard USB device or a charger is connected to the
USB port. The FAN3988 also monitors the VBUS for
over- or under-voltage conditions. The FLAG2 pin is set
LOW if VBUS is less than 3.3 V or greater than 6.0 V.
In a condition where the USB port is connected to a
standard USB device, the D+ input is pulled up to VDD
(system supply) in parallel with the 1.5 kΩ on a USB
transceiver with a parallel R value of 1.497 kΩ. The D-
input is connected to a 15 kΩ pull-down by the USB
device and in parallel with 5 MΩ with a parallel R value
of 14.955 kΩ. This condition makes flag1 LOW.
In a condition where a USB transceiver is not
incorporated or there is a switch between the USB port
and the FAN3988, external resistors must be used to
set the correct input logic states on the D+ D- inputs. A
5 MΩ pull-down on the D- line and a 1 MΩ pull-up to
VDD (system supply) on the D+ line are recommended.
If D+ and D- are open (floating), D+ is pulled to VDD
(system supply) and D- floats LOW, which makes
flag1 LOW.
