Say goodbye to cross-country road trips
Leland Teschler • Executive editor Officials estimate it will cost $50 billion to field the chargers needed for the expected number of electric vehicles on U.S. roads by 2030. But it’s possible that spending every penny of this amount won’t prevent the extinction of the cross-country road trip. Here’s the logic behind that statement: It’s […]
High-current/low-inductance power inductors handle automotive apps
TDK Corporation developed new HPL505032F1 power inductors for use in automotive circuits. The inductors enable level 5 ADAS applications for cameras by offering high-current and low-inductance for power circuits in central processing units and graphic processing units, such as advanced driver-assistance systems (ADAS). The new products achieve high power efficiency by adopting a low-resistance frame […]
Fast recovery epitaxial diodes feature low reverse leakage/reverse recovery charge
Taiwan Semiconductor announces the availability of the PU1xMx / PU2xMx families of fast recovery epitaxial diodes. This high-reliability (AEC-Q101 qualified) FREDs offer optimized switching speed vs. reverse recovery time. Their soft reverse recovery results in lower noise switching while achieving low losses and increased efficiency. The Micro SMA package heat spreader contacts provide excellent heat […]
IGBTs incorporate 650-V SiC Schottky barrier diode
ROHM Semiconductor announced the RGWxx65C series of hybrid IGBTs with an integrated 650V SiC Schottky barrier diode. The devices, qualified under the AEC-Q101 automotive reliability standard, are ideal for automotive and industrial applications that handle high power, such as photovoltaic power conditioners, onboard chargers, and DC/DC converters used in electric and electrified vehicles (xEVs). The RGWxx65C […]
Common-mode chokes designed for noise suppression in high-speed interfaces
Murata has released two new automotive common mode choke coils intended for noise suppression in high-speed interfaces that use Serializer/Deserializer (SerDes) on Power Over Coax (PoC). In-vehicle cameras have become increasingly popular in the autonomous vehicle market. SerDes is typically used in image data transmission interfaces. This, in turn, has led to the deployment of […]
Common-mode chokes optimized for high-speed interface noise suppression
Murata has released two automotive common mode choke coils intended for noise suppression in high-speed interfaces that use Serializer/Deserializer (SerDes) on Power Over Coax (PoC). Since this application requires a higher current compared to conventional differential interfaces, the DLW21SH391XQ2 and DLW21PH201XQ2 were developed specifically to handle a range from 300mA to 500mA. With sensor nodes becoming more compact, […]
Isolated buck converters boast wide input voltage range of 4 V to 48 V
Optimized for isolated buck regulator designs, the STMicroelectronics A6986I and L6986I DC/DC converter ICs have a wide input-voltage range and low quiescent current to ensure robust and energy-efficient operation in automotive and industrial applications up to 5W. The isolated buck topology drastically lowers the bill of materials in systems that require a regulated non-isolated primary voltage and one […]
