SGM4551B - Dual Bidirectional I2C Bus and SMBus Voltage-Level Translator

SG Micro

General Description

The SGM4551B is a 2-bit, SMbus, dual, bidirectional, I2C voltage translator with the ability of enable (EN) function.

For VREF1, the typical operation range is from 1.2V to 3.3V and the typical operation for VREF2 is from 1.8V to 5.5V.

The signal can be transmitted bilaterally from 1.2V to 5V.

SGM4551B Dual Bidirectional I2C Bus and SMBus Voltage-Level Translator GENERAL DESCRIPTION The SGM4551B is a 2-bit, SMbus, dual, bidirectional, I2C voltage translator with the ability of enable (EN) function. For VREF1, the typical operation range is from 1.2V to 3.3V and the typical operation for VREF2 is from 1.8V to 5.5V. The signal can be transmitted bilaterally from 1.2V to 5V. The propagation delay is significant small as the low on-resistance of SGM4551B. Also, if the EN pin is in high position, the voltage translator is transparent and then it allows the connection between SCL1 and SCL2, SDA1 and SDA2 respectively. In addition, in this state, the transmitting direction is bidirectional.
