ID and Manufacturer Register Address Map
Table 16 provides the contents of the ID registers of the
MAX3301E. Addresses 00h and 01h comprise the ven-
dor ID registers. Addresses 02h and 03h comprise the
product ID registers. Addresses 14h and 15h comprise
the revision ID registers.
Audio Car Kit
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:
Audio input
Audio output
Charging
Control and status
The MAX3301E allows support of the CEA-936A car kit
interface standard.
External Components
External Resistors
Two external resistors (27.4
±1%) are required for
USB connection. Install one resistor in series between
D+ of the MAX3301E and D+ of the USB connector.
Install the other resistor in series between D- of the
MAX3301E and D- of the USB connector (see the
Typical Operating Circuit
).
External Capacitors
Five external capacitors are recommended for proper
operation. Install all capacitors as close to the device as
possible. Decouple V
L
to GND with a 0.1μF ceramic
capacitor. Bypass V
CC
to GND with a 1μF ceramic
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
BUS
to GND
with a 1μF to 6.5μF ceramic capacitor in accordance
with USB OTG specifications.
ESD Protection
To protect the MAX3301E against ESD, D+, D-, ID_IN,
and V
BUS
have extra protection against static electricity
to protect the device up to ±15kV. The ESD structures
withstand high ESD in all states; normal operation, sus-
pend mode, interrupt shutdown, and shutdown. For the
ESD structures to work correctly, connect a 1μF or
greater capacitor from TRM to GND and from V
BUS
to
GND. ESD protection can be tested in various ways; the
D+, D-, ID_IN, and V
BUS
inputs/outputs are character-
ized for protection to the following limits:
±15kV using the Human Body Model
±6kV using the IEC 61000-4-2 Contact Discharge
Method
±10kV using the IEC 61000-4-2 Air-Gap Discharge
