LTM2894 Isolated USB Data Transceiver FEATURES DESCRIPTION n Isolated USB Transceiver: 7500V for 1 Minute The LTM 2894 is a complete galvanically-isolated USB 2.0 RMS n CSA (IEC/UL) Approved, File 255632 compatible Module (micromodule) transceiver. n Reinforced Insulation The LTM2894 is ideal for isolation in host, hub, bus split- n USB 2.0 Full Speed and Low Speed Compatible ter or peripheral device applications. It is compatible with n Auto-Configuration of Bus Speed USB 2.0 full speed (12Mbps) and low speed (1.5Mbps) n 4.4V to 36V V and V Operating Range BUS BUS2 operation. Automatic speed selection configures integrated n 3.3V LDO Output Supply Signal References V and LO pull-up resistors on the upstream port to match those V LO2 sensed on the downstream device. n 50kV/s Common Mode Transient Immunity n The isolator Module technology uses coupled inductors 20kV HBM ESD on USB Interface Pins n to provide 7500V of isolation and 17.4mm of creepage 1414V Maximum Continuous Working Voltage RMS PEAK n between the upstream and downstream USB interface. 17.4mm Creepage Distance n This device is ideal for systems requiring isolated ground 22mm 6.25mm Surface Mount BGA returns or large common mode voltage variations. Uninter- rupted communication is guaranteed for common mode APPLICATIONS transients greater than 50kV/s. n Isolated USB Interfaces Enhanced ESD protection allows this part to withstand n Host, Hub, or Device Isolation up to 20kV (human body model) on the USB transceiver n Industrial/Medical Data Acquisition interface pins to local supplies and 20kV through the isolation barrier to supplies without latchup or damage.
