Description

The MAX3301E fully integrated USB On-the-Go (OTG) transceiver and charge pump allows 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 with an embedded USB host to directly connect to peripherals such as printers or external hard drives.

The MAX3301E integrates a USB OTG transceiver, a VBUS charge pump, a linear regulator, and an I2C™- compatible, 2-wire serial interface. An internal level shifter allows the MAX3301E to interface with logic supply voltages from +1.65V to +3.6V. The MAX3301E's OTG-compliant charge pump operates with +3V to +4.5V input supply voltages, and supplies an OTG-compatible output on VBUS while sourcing more than 8mA of output current.

The MAX3301E enables USB OTG communication from highly integrated digital devices that cannot supply or tolerate the +5V VBUS levels that USB OTG requires. The device supports USB OTG session-request protocol (SRP) and host-negotiation protocol (HNP) by controlling and measuring VBUS using internal comparators.

The MAX3301E provides built-in ±15kV electrostaticdischarge (ESD) protection for the VBUS, ID_IN, D+, and D- terminals. The MAX3301E is available in 5 x 5 chip-scale (UCSP™) and 32-pin (5mm x 5mm x 0.8mm) thin QFN packages and operates over the extended -40 to +85 temperature range.
