Industry's Smallest and Lowest (V) Full-Speed USB Transceivers, with Low VIO 3/5-Wire Interface

The MAX14581/MAX14582 USB-compliant transceivers are designed to minimize the area and external components required to interface low-voltage ASICs to USB. These devices comply with USB 2.0 specification for fullspeed-only (12Mbps) operation. The transceivers include an internal 3.3V regulator, an internal 1.5kΩ 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 13µA (typ) from VBUS. An enumerate function controls the D+ pullup resistor, allowing devices to logically disconnect while remaining plugged in.

The devices have 36Ω (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 15kΩ pulldown resistors and driving ENUM logic-low.

The MAX14581 (3-wire) is equipped with DAT and SE0 interface signals. The transceiver provides a USB detection function that monitors the presence of USB VBUS and 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 VBUS in the MAX14582 is encoded as VP = VM = logic-high.

These devices operate over the extended -40°C to +85°C temperature range and are available in 12-bump WLP packages.
