Voltage level shifters from Diodes are designed for automotive systems
Voltage-level shifters available from Diodes have been extended to include the PI4ULS3V304AQ. It uses advanced level shifting technology for modern automobile design, says Diodes. It addresses the challenge of lower voltage microprocessors and microcontrollers incorporated into automotive systems, which are required to drive external devices operating at different voltage levels to their own (such as sensors and EMI filters).
The four-bit IC supports a guaranteed data rate of 140Mbits per second, to enable high speed operation. The ability to offer bi-directional, voltage-level translation, allows push-pull applications to be addressed.
Through the PI4ULS3V304AQ’s A and B ports, two different power supply rails can be tracked. The IC can offer 0.9 to 2.0V translation on the A port and translation from 1.65 to 3.6V on the B port. Propagation delay is kept to just 13 nano seconds while running at full 100pF capacitive drive. The AEC-Q100 Grade 1-qualified device is suitable for infotainment, driver assistance and telematics in automotive systems.
Operating temperature range is -40 to +125 degrees C and there is also 2kV electro-static discharge (ESD) protection. The innovative output enable (EN) function means that either of the PI4ULS3V304AQ’s respective I/O ports (A or B) can be shut down when not needed, in order to lower the power draw. Automated bi-directional operation eliminates the need for inclusion of a direction control pin.
Diodes supplies the PI4ULS3V304AQ in a 12-pin UQFN package.
Diodes supplies semiconductor products to companies in the consumer electronics, computing, communications, industrial, and automotive markets. Its portfolio includes discrete, analogue and mixed signal products with packaging technology. It to meet customers’ needs. The company has operations in 31 sites around the world, including engineering, testing, manufacturing, and customer service.
