OBDII is the second-generation onboard diagnostic (OBD) interface. The first generation of OBD coincided with the advent of onboard computers in vehicles. Initial OBD systems were intended to provide technicians with information on the status of various vehicle systems, with an indicator light on the dash to alert drivers of a malfunction. OBDII includes more […]

How is the MOST bus optimized for the automotive industry?
The media-oriented systems transport (MOST) bus was initially intended for implementation on optical fiber to support high bit rates, but fiber and copper transport layers are currently defined. MOST provides a solution for automotive peripherals like radios, CD and DVD players, GPS navigation systems, and infotainment electronic control units (ECUs). This FAQ describes the MOST […]
Automotive-grade three-terminal MLCC provides 4.3 µF in a 0402-in size.
Murata today announced it has set a new capacitor performance benchmark with the introduction of its NFM15HC435D0E3. The product is the world’s first automotive-grade three-terminal multi-layer ceramic capacitor (MLCC) to provide a capacitance of 4.3 µF in a 0402-inch (1.0 × 0.5 mm) size. It also delivers superior power decoupling and noise removal, which are […]
Software-defined vehicles, cool technology, and car interiors to drool over at AutoTech: Detroit
The AutoTech: Detroit (formerly the TU Automotive) event took place in Novi, Mich. recently and featured about 100 exhibits plus conference tracks on ADAS and autonomous technology, connectivity, and mobility. Also part of the event was the Wards Auto Interiors & UX conference. We had a chance to tour the show floor and in some […]

Finding the correct LiDAR application
The automotive ADAS designers tout the up-and-coming LiDAR detection technology, coupled with mmWave radar and the camera, to support autonomous vehicle design further. But this is not the complete LiDAR story. Let’s see what happens when engineers get this new toy. This technology, combined with GPS, is finding a home in agriculture, astronomy, oceanography, cameras, […]
How fast can Li-on batteries be charged?
The speed at which a battery can be recharged is measured using the ‘C-rate,’ where ‘C’ is the battery’s capacity in mA or A. At a 1 C rate, a battery can be completely recharged in one hour. The speed of charge primarily depends on the voltage. For example: For small batteries used in portable…
