A level shifter, also known as a logic-level shifter or voltage level translator, is a circuit used in digital electronics to translate signals from one logic level or voltage domain to another.
This enables compatibility between integrated circuits with various voltage requirements, such as TTL and CMOS. Level shifters are used in contemporary systems to connect the domains of processors, logic, sensors, and other circuits.
Although levels above and below these voltages are also utilised, the three logic levels that have been used most frequently in recent years have been 1.8V, 3.3V, and 5V. They can be used to convert voltages, either from a higher input voltage to a lower output voltage or from a lower input voltage to a higher output voltage.
The ALVC, AVC, and LVC device families contain these gadgets, which have low power consumption. Translators are crucial because they enable communication and mutual learning. Without precise and efficient translation, we would not be able to share ideas and collaborate with other communities, and the globe would have lagged far behind.
The Global EV Level translator market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
A dual, EV Level translator, isolated MOSFET driver using in-house HVCMOS® technology is launched the HT0440. Discrete MOSFETs that are set up as unidirectional or bidirectional switches can be driven by it. N-channel MOSFETs can be driven as high-side switches up to 400V.
When logic inputs A and B are at logic high, the HT0440 generates two independent DC isolated voltages to the outputs, VOUTA and VOUTB. By connecting an external clock signal to the CLK pin, the HT0440’s internal clock can be turned off. As a result, the power dissipation and AC characteristics can be customised to match certain requirements.
While not in use, the CLK pin ought to be connected to ground. The two logic inputs, A or B, when they are at logic high, provide the internal supply voltage for the HT0440, eliminating the need for any external power sources. Please refer to application note AN-D26 for information on specific circuit application details.
