addressed at I
locations 16h, 17h) to support USB OTG SIE implemen-
tations that are limited to I
between 0h and 15h.
Table 17 provides the contents of the ID registers of the
MAX3301E/MAX3302E. Addresses 00h and 01h com-
prise the vendor ID registers. Addresses 02h and 03h
comprise the product ID registers. Addresses 14h and
15h comprise the revision ID registers.
Many cell phones are required to interface to car kits.
Depending upon the car kit, the interface to the phone
may be required to support any or all of the following
functions:
•
•
•
•
D+ and D- of the MAX3301E/MAX3302E go to a high-
impedance state when in shutdown mode, allowing
external signals (including audio) to be multiplexed onto
these lines.

Two external resistors (27.4Ω ±1%) are required for
USB connection. Install one resistor in series between
D+ of the MAX3301E/MAX3302E and D+ of the USB
connector. Install the other resistor in series between D-
of the MAX3301E/MAX3302E and D- of the USB con-
nector (see the Typical Operating Circuit ).
Five external capacitors are recommended for proper
operation. Install all capacitors as close to the device as
possible. Decouple V
capacitor. Bypass V
capacitor. Bypass TRM to GND with a 1µF (or greater)
ceramic or plastic capacitor. Connect a 100nF flying
capacitor between C+ and C- for the charge pump (see
the Typical Operating Circuit ). Bypass V
with a 1µF to 6.5µF ceramic capacitor in accordance
with USB OTG specifications.
To protect the MAX3301E/MAX3302E against ESD, D+,
