USB Transceivers, with Low VIO 3/5-Wire Interface
The MAX14581/MAX14582 USB-compliant transceivers
are designed to minimize the area and external compo-
nents required to interface low-voltage ASICs to USB.
These devices comply with USB 2.0 specification for full-
speed-only (12Mbps) operation. The transceivers include
an internal 3.3V regulator, an internal 1.5kI D+ pullup
resistor, and built-in ±15kV ESD HBM protection circuitry
to protect the USB I/O ports (D+, D-). The MAX14581/
MAX14582 also have internal series resistors, allowing the
devices to be wired directly to a USB connector.
These devices operate with logic-supply voltages as low
as +1.2V, ensuring compatibility with low-voltage ASICs.
A low-power disable mode reduces current consumption
to typically less than 13FA (typ) from V
function controls the D+ pullup resistor, allowing devices
to logically disconnect while remaining plugged in.
The devices have 36I (typ) internal series resistors
on D+/D- for direct connection to the USB connector.
These devices can be used as either peripheral or host
(FS) USB transceivers. As a host USB transceiver, the
MAX14581/MAX14582 require external 15kI pulldown
resistors and driving ENUM logic-low.
The MAX14581 (3-wire) is equipped with DAT and SE0
interface signals. The transceiver provides a USB detec-
tion function that monitors the presence of USB V
signals the event by means of a BD pin.
The MAX14582 (5-wire) is equipped with VP, VM, and
RCV interface signals. The detection of V
MAX14582 is encoded as VP = VM = logic-high.
These devices operate over the extended -40NC to
+85NC temperature range and are available in 12-bump
WLP packages.
