I2C and SMBus  Voltage Level Translator

iVoLTTM (pronounced “i-volt”), is an I2C Voltage Level Translator module that gives system developers and test engineers a bridge to low voltage I2C and SMBus devices operating down to 1.5 volts.

As portable device developers strive to reduce power budgets, they must deal with devices and interconnect buses operating at low voltages. Since I²C plays a big part in multi-media consumer products, it is only natural that low voltage devices are using I²C for its cost, space, and power saving features.

The iVoLT is an I²C Bus voltage translator module, designed to interface standard I²C and SMBus devices operating at different voltage levels. Based on Gunning Transceiver Logic-Transceiver voltage clamps, the iVoLT translates I²C Bus high voltage (3.3 V to 5 V) Clock, Data, and /INT signals to I²C Bus low voltage (at least 1 Volt below high side) signals. Supporting bi-directional I²C Bus voltage level translation, the iVoLT provides voltage translation between buses operating at up to 400 kHz.
