General Description

The MAX3301E/MAX3302E fully integrated USB On-the-

Go (OTG) transceivers and charge pumps allow mobile

devices such as PDAs, cellular phones, and digital

cameras to interface directly with USB peripherals and

each other without the need of a host PC. Use the

MAX3301E/MAX3302E with an embedded USB host to

directly connect to peripherals such as printers or

external hard drives.

The MAX3301E/MAX3302E integrate a USB OTG trans-

ceiver, a V

BUS

charge pump, a linear regulator, and an

C-compatible, 2-wire serial interface. An internal level

shifter allows the MAX3301E/MAX3302E to interface

with +1.65V to +3.6V logic supply voltages. The

MAX3301E/MAX3302E’s OTG-compliant charge pump

operates with +3V to +4.5V input supply voltages, and

supplies an OTG-compatible output on V

BUS

while

sourcing more than 8mA of output current.

The MAX3301E/MAX3302E enable USB OTG communi-

cation from highly integrated digital devices that cannot

supply or tolerate the +5V V

BUS

levels that USB OTG

requires. The device supports USB OTG session-request

protocol (SRP) and host-negotiation protocol (HNP).

The MAX3301E/MAX3302E provide built-in ±15kV elec-

trostatic-discharge (ESD) protection for the V

BUS

, ID_IN,

D+, and D- terminals. The MAX3301E/MAX3302E are

available in 25-bump chip-scale (UCSP™), 25-bump

WLP package, 28-pin TQFN, and 32-pin TQFN pack-

ages and operate over the extended -40°C to +85°C

temperature range.

USB On-the-Go Transceivers and Charge Pumps The USB OTG specification defines a dual-role USB device that acts either as an A device or as a B device. The A device supplies power on V BUS and initially serves as the USB host. The B device serves as the initial peripheral and requires circuitry to monitor and pulse VBUS. These initial roles can be reversed using HNP. The MAX3301E/MAX3302E combine a low- and fullspeed USB transceiver with additional circuitry required by a dual-role device.

MAX3301E/MAX3302E USB On-the-Go Transceivers and Charge Pumps session end comparator threshold. Figure 12 shows the level-detector comparators. The interrupt-enable registers (Tables 12 and 13) determine whether a falling or rising edge of VBUS asserts these status bits. ID_IN The USB OTG specification defines an ID input that determines which dual-role device is the default host. An OTG cable connects ID to ground in the connector of one end and is left unconnected in the other end.
PAGE 15
USB On-the-Go Transceivers and Charge Pumps Operating Modes The MAX3301E/MAX3302E have four operating modes to optimize power consumption. Only the I2C interface remains active in shutdown mode, reducing supply current to 1µA. The I2C interface, the ID_IN port, and the session-valid comparator all remain active in interrupt shutdown mode. RCV asserts low in suspend mode; however, all other circuitry remains active. Table 1 lists the active blocks’ power in each of the operating modes.

MAX3301E/MAX3302E USB On-the-Go Transceivers and Charge Pumps 2-Wire I2C-Compatible Serial Interface A register file controls the various internal switches and operating modes of the MAX3301E/MAX3302E through a simple 2-wire interface operating at clock rates up to 400kHz. This interface supports data bursting, where multiple data phases can follow a single address phase. Table 2.

USB On-the-Go Transceivers and Charge Pumps Bit Transfer One data bit is transferred during each clock pulse. The data on SDA must remain stable while SCL is high (see Figure 16). Acknowledge The acknowledge bit (ACK) is the 9th bit attached to any 8-bit data word. ACK is always generated by the receiving device. The MAX3301E/MAX3302E generate SDA SCL DATA LINE STABLE, CHANGE OF DATA DATA VALID ALLOWED an ACK when receiving an address or data by pulling SDA low during the ninth clock period.
