· Infineon to supply advanced power chips for Xiaomi EVs

TAIPEI -- Top German chipmaker Infineon has reached an agreement to supply Chinese EV maker Xiaomi with advanced power semiconductors until 2027, in a move to tap the growing electric car market in China and beyond.Infineon said on Monday that it will provide Xiaomi's electric cars with its silicon carbide (SiC) chips and modules, as well as a wide range of key microcontroller chips. The chipmaker said the collaboration can "reinforce Infineon's position as the global market leader in automotive semiconductors."Xiaomi, which is also the world's third-largest smartphone maker, started selling its first electric vehicle in March. It aims to shake up the EV market with its premium SU7 Max, priced at 299,900 yuan ($41,500), compared with 684,900 yuan for Tesla's Model S and 1.5 million yuan for an electric Porsche.Zhenyu Huang, vice president of Xiaomi EV and general manager of its supply chains, said the deepening ties with Infineon will not only "help stabilize the supply of silicon car...

· STMicroelectronics launches automotive gate driver for system monitoring and protection

Technology company STMicroelectronics has introduced the L99H92 automotive gate driver which provides an SPI port for programming and diagnostics, a charge pump, protective features and two extra current-sense amplifiers for system monitoring.Featuring two high-side and two low-side drivers, the L99H92 can control a single H-bridge powering one bidirectional DC motor or two half bridges for two unidirectional motors. Common applications for this driver include electric sunroofs, window lifts, powered trunks, sliding doors and seat-belt pre-tensioners.The built-in charge pump provides stable operation of the high-side drivers even as the vehicle battery voltage fluctuates, which the company says enables the outputs to function reliably with a supply voltage as low as 5.41V.The charge-pump output can be accessed externally to control a metal–oxide–semiconductor field-effect transistor (MOSFET) for reverse-battery protection.The gate-driving current is programmed through the...
