How does SLAM help autonomous vehicles?
SLAM (simultaneous localization and mapping) is used in autonomous vehicles of all types to build a map and simultaneously locate the vehicle in that map. SLAM algorithms allow the vehicle to analyze and map out unknown environments. With this map information, the vehicle can implement path planning and obstacle avoidance. Visual SLAM uses cameras and/or […]
Compact intelligent power modules target home-appliance power inverter apps
Infineon Technologies AG adds a new member to the CIPOS Tiny Intelligent Power Module (IPM) family: the CIPOS Tiny IM323-L6G 600 V 15 A. The new IPM is based on TRENCHSTOP IGBT RC-D2 switches and state-of-the-art SOI gate driver technology to realize maximum efficiency and improved reliability, along with minimized system size and cost. The […]
Why I’m divided on “Right to Repair”
Mandating a “right to repair” seems like a good idea, but what are the details and risks? As an engineer, I like to fix things, or at least try to. That’s why I have been following the “right to repair” (RTR) movement, which is getting a lot of attention these days (just Google it and […]
Common-source dual GaN FET features 58 mΩ RDS(on), 20-A pulsed output current
EPC announces the introduction of the EPC2221, a common source dual gallium nitride FET rated at 100 V, 58 mΩ, and 20 A pulsed current. The EPC2221 can be used in lidar systems for robots, surveillance systems, drones, autonomous cars, and vacuum cleaners. The low inductance and capacitance of the EPC2221 allow fast switching (100 […]
Thick-film resistors feature high temperature stability
Commercial and industrial power electronics increasingly demand robust power supplies with high stability and low thermal resistance. For these requirements, standard chip resistors may not be the best solution. Wide terminal chip resistors, such as Stackpole’s RMCW, provide terminations on the long sides of the chip to provide better current handling and thermal resistance. The […]
Secure storage subsystem handles Qi 1.3 wireless charging
In order to ensure high-quality wireless charging power transmitters, the Wireless Power Consortium (WPC) has released the Qi 1.3 specification with the extended power profile. This new specification created a demand for high-security silicon authentication devices for full-service support. In response, Microchip Technology Inc. is announcing the new industrial-grade TrustFLEX ECC608 and the automotive-grade Trust Anchor TA100 combined […]
