Logic - Translators, Level Shifters: FXL5T244BQX Application Field and Working Principle

Logic translators and level shifters are widely used to connect different types of electronic components, which require different signal levels. They can be used in many areas, such as medical, consumer, automotive and industrial applications. FXL5T244BQX is an industry-leading ultra low voltage bidirectional logic translator and level shifter, which is designed with global 5V regulated single supply and advanced MOSFET technology. It is especially suitable for wide voltage applications that require both 5V and 3V logic level compatibility.

Application Field

The FXL5T244BQX can be widely used in consumer, automotive and industrial applications, such as industrial control, digital signal interface and communication systems. The FXL5T244BQX is also suitable for communication-related applications, such as digital television, STB (set-top boxes) and mobile phones. It can be used to connect ICs (integrated circuits) with different signal levels and ensure signal compatibility.In addition, the FXL5T244BQX is an ideal bridge solution for use in systems that require both 5V and 3V logic levels, such as motor control and power management applications.

Working Principle

The FXL5T244BQX adopts advanced MOSFET technology, which allows the two type voltages to be changed in the same chip. It achieves bidirectional level shifting and transfers signals between the two type of ICs (integrated circuits), without affecting the performance of their circuits. The FXL5T244BQX chips are connected together in a multistage cascade to form a voltage level shifting circuit. The input voltage is transferred from the low to the high voltage level by the high voltage level MOSFET, and then the output of the high voltage supply is returned to the low voltage level MOSFET by the low voltage MOSFET at an appropriate time interval. Meanwhile, the FXL5T244BQX chips use the reference voltage obtained from the voltage divider between the high and low voltages to ground. This reference voltage is used either to set the driving voltage of the MOSFETs, or as bias voltage. The reference voltage is also used to detect the output voltage of the MOSFETs, to ensure that the output of the translated signal is accurate.

Conclusion

The FXL5T244BQX is an advanced ultra low voltage bidirectional logic translator and level shifter, which is suitable for wide voltage applications that require both 5V and 3V logic level compatibility. It adopts advanced MOSFET technology to transfer the voltage level between two type ICs, without affecting their performance. The FXL5T244BQX can be used in consumer, automotive and industrial applications, such as digital television, STB (set-top boxes) and motor control. The FXL5T244BQX chips are also connected together in a multistage cascade to form a voltage level shifting circuit, which uses reference voltage to detect the output voltage of the MOSFETs for accurate signal translation.
