Functional Description
The FUSB1500 transceiver is designed to convert
CMOS data into USB differential bus signal levels and to
convert USB differential bus signals to CMOS data. The
FUSB1500 supports the SE Mode interface from the
controller and has an extended Control Mode that
enables a simplified dedicated charger functionality via a
weak pull-up resistance (nominally 125k
). This mode is
described in Table 4.
To minimize EMI and noise, the outputs are edge-rate
controlled with the rise and fall times defined for full-
speed (12Mbps) and low-speed (1.5Mbps) data rates.
The rise and fall times are balanced between the
differential pins to minimize skew.
The FUSB1500 is defined as a self-powered device, or
bus-powered where the regulation down to 3.3V is
external to the FUSB1500, so it accepts the regulated
3.3V as its supply input. The VIO rail supports I/Os of
1.65V to 3.6V.
If VIO is lost, the pins go into the high-Z state. If VIO is
present, but the VREG3V3 power supply is lost, the high-Z
detection circuit still functions.
USB Mode
Table 1 describes the specific pin functionality when
USB Traffic Mode is selected. This is also referred to as
normal mode. Table 2 and Table 3 describe the specific
truth tables for driver and receiver operating functions.

Notes:
16. Signal levels on the D+ and D- pins are determined by external connections and Table 4 (Extended Control
Configurations).
17. When in Suspend Mode (see Table 4 for suspended configurations), the differential receiver is inactive and the
RCV output is forced LOW. Out-of-suspend signaling (K) is detected via the single-ended receiver outputs VP
and VM.
18. The states of VP and VM are functions of signal levels on D+/D- in normal mode.

Note:
20. VP = VM = HIGH indicates Sharing Mode.
21. Denotes the signal level on output RCV prior to the SE0 event. This level is stable during the SE0 event period.
22. Sharing mode is not a function of D+/D- but is entered when VIO is present and VREG3V3 is disconnected.
