The FXLP34P5X Logic-Translators, Level-Shifters is a device from the family of products under the “Viva-Lite” brand from Samsung Electronics. The FXLP34P5X is an integrated circuit consisting of N-Channel and P-Channel low-voltage MOSFET-based level shifters. It combines the functions of level-shift and logic translator in one package. It is very popular in the automotive industry due to its compact size and efficiency.

The FXLP34P5X offers the choice of two operating modes, the Bi-directional (BT) mode and the Uni-directional (UT) mode. In both of these modes, the device translates the input signals from 5V CMOS VCC level to 3.3V levels. The level-shifting is done by using a low-current charge-pump technique. The device offers a wide range of supply voltage options, from 3.0V to 5.6V. It also has a pin for Mode Selection, which can be used to select between the BT and UT operating modes.

The primary application field of the FXLP34P5X is the automotive industry. It is used to level-shift signals between low-voltage (3.3V) and high-voltage (5V) components in automotive engines and other systems. The device is also suitable for applications where a bidirectional level shift is required, such as in communication interface buses and embedded systems.

In terms of its working principle, the FXLP34P5X works by using a charge-pump technique. This is accomplished by using two configured back-to-back power MOSFETs connected in series across the input and output supply voltage (VCC and VCCs). The MOSFETs act to level-shift the signals from the low-voltage side to the high-voltage side by using a charge pump technique.

When the device is in the Bi-directional mode, a single FET acts as a level-shifter, and a Bi-directional Connection is made between the input and the output sides. This allows both high-side and low-side voltages to be level-shifted across the same pair of FETs. As the input signal switches between the high and low states, the MOSFETs switch states accordingly, thereby maintaining the desired VCC and VCCs voltage levels at the output.

When the device is in the Uni-directional mode, the two MOSFETs are used in parallel, with one acting for signal level shifting from the Low-Voltage to the High-Voltage side, and the other acting for level-shifting from the High-Voltage to the Low-Voltage side. Thus, the Uni-directional mode allows the division of the input signal into two parts, each of which is then level-shifted separately.

Overall, the FXLP34P5X Logic-Translators, Level-Shifters is a high-performance device that provides a simple and efficient way to level-shift signals between low-voltage and high-voltage systems. Its primary application is in the automotive industry, but it can also be applied in communication interface buses and embedded systems. The device uses a charge-pump technique to level-shift signals, and offers bothBi-directional and Uni-directional modes of operations.
