I2C Bus 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. NOTE: If you are working with low-voltage I2C Bus, you may be interested in our iPort/USB 2 I2C Bus host adapter with Circuit Sense.

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.
