ST6G3237BTBR

Logic - Translators, Level Shifters

The ST6G3237BTBR is a type of differentiating logic-level translators from STMicroelectronics that operate from a single 1.65 to 3.6 V supply with 400mA output drive, allowing for translation from a low-voltage logic level to a higher voltage one.

It is especially suited for the translation from open-drain and push-pull outputs from low voltage I2C-Bus and SMBus components toLevels compatible with standard microcontroller banks which can be up to 3.6 V.

Applications for these types of logic-level translators are numerous. ST6G3237BTBR can be used in control systems, digital processing systems and industrial control systems. It can be used in automotive applications. The key advantages of this type of translators can be found in digital communication, battery management systems and LED backlight in lCD displays.

Working Principle

The ST6G3237BTBR is a full bridge logic translator. It contains two NMOS transistors and two PMOS transistors, controlled by the voltage of VGATE. The VB and VI pins on the chip control the performance of the logic-level translators. VB is a bridge voltage pin, and VI is an input voltage pin. The output voltage (VO) will depend on the voltage of VI and VB. If VI is greater than VB, VO will be equal to VB. If VI is less than VB, then VO will be equal to VI.

ST6G3237BTBR works as a high-level transfer in this work mode. This means a low input voltage (VI) will generate a low output voltage (VO). It is important to note that the output voltage will still be limited to the voltage value of VB. The logic-level translator can work as a low-level transfer as well, when VI is greater than VB. In this case, a high input voltage will generate a high output voltage.

The advantage of these types of logic-level translators is that they are able to automatically detect the incoming signal from the low-voltage device, and then manually switch between the low and high voltages if necessary. This allows for different types of low-voltage signals and digital systems to interface together without any external circuitry or components. The ST6G3237BTBR is especially suited for the translation from push-pull and open-drain outputs from low voltage I2C-Bus and SMBus components to levels compatible with standard microcontroller banks.
