MAX3301E, MAX3302E
USB On-the-Go Transceivers and Charge Pumps
First ±15kV ESD-Protected USB On-the-Go Transceiver and Charge Pump
|
Status
Active: In Production.
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 transceiver, a VBUS charge pump, a linear regulator, and an I²C-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 VBUS while sourcing more than 8mA of output current.
The MAX3301E/MAX3302E enable 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).
The MAX3301E/MAX3302E provide built-in ±15kV electrostatic-discharge (ESD) protection for the VBUS, 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 packages and operate over the extended -40°C to +85°C temperature range.
