Melexis has created a magnetic sensor with functional safety for steer-by-wire systems. “For innovations like steer-by-wire systems, position sensors are a critical component that must exhibit exceptional reliability, functional safety and accuracy,” it said. “The requirements for sensors in electric vehicles are heightened, necessitating excellent EMC robustness and stray field immunity. Simultaneously, solutions must be easy to integrate.” MLX90427 as ...

Molex has introduced MX-Dash, a family of single automotive connectors that combine power, signal and high-speed data inserts for zonal architectures. In wire-to-wire and wire-to-board form, they are aimed at autonomous driving modules, cameras, GPS, infotainment, lidar, displays and sensors. There are sealed and un-sealed options, and configurations with 0.50, 0.64, 1.20, 1.50, 2.80 or 4.80mm terminals as well as coaxial ...

HMI, the analogue and power management specialist, has launched its HL8518, a single-chip 80 mΩ high-side switch ideal for automotive applications needing power switch for low wattage lamp, high-side relays and valves, and general resistive, inductive, and capacitive loads. The HL8518 is a single-channel, high-side power switch with 80mΩ (typical) Rds(on) power FET. It combines comprehensive diagnostic capabilities, full protection ...

Recom has created a chassis-mount isolated dc-dc converter for nominal battery voltages from 24 to 90V. Called RMOD360-UW, it can deliver full power continuously with inputs between 27 and 106V, as well as 240W down to 18V, and it will deliver 360W from up to 126V for 10 minutes. Output is 24.5Vdc. A 300W relative, RMOD300-UW, comes in three versions ...

Infineon is aiming at 24 and 48V ancillary motors in vehicles, with a three-phase bridge gate driver with advanced protection features. “The gate driver IC offers functional safety according to ISO 26262 ASIL B,” according to Infineon. “It has a range of protection functions such as timeout-watchdog, drain-source monitoring, over-voltage, under-voltage, cross-current and over-temperature protection, as well as off-state diagnostics.” ...

Samsung is aiming at electric vehicle on-board chargers with a 1,000v 22nF multi-layer ceramic capacitor. CL32C223JIV1PN# (yes, there is a # in the part number) is aimed at CLLC resonant power supply topologies and is constructed with a COG dielectric. Operation is across -55 to +125°C and it has a ±5% tolerance. Packaging is a 2.5mm tall 3.2 x 2.5mm ...

Last week Belgian fabless chip company Melexis announced a unique inductive sensing IC that includes a tiny transformer, drive circuit and sense circuit, so Electronics Weekly decided to have a closer look. No permanent magnet, external or internal, is needed, and external magnetic fields are rejected. MLX92442 only requires a nearby electrically conductive object for triggering. It comes in either ...

Infineon has had its forthcoming TC4x automotive microcontrollers cleared for safe AI processing by the Fraunhofer Institute for Cognitive Systems (IKS). “Embedded AI is becoming increasingly important for safety-critical real-time applications,” said Infineon. “However, this also creates new requirements and standards that must be considered during the complete product lifecycle.” The TC4x family includes ‘PPU’ (parallel processing unit), an AI-accelerator ...

Programmierbare Logik & Systeme is offering debug and trace for NXP’s S32N55 16 core software-defined vehicle processor, announced yesterday. It is included in the 2024 version of UDE, the company’s universal debug engine. With UDE “the Cortex-R52 main cores and the Cortex-M7 auxiliary cores are all visible and can be controlled from one common debugger user interface”, according to PLS. ...

NXP has announced a real-time processor for vehicle central control computers with 16 1.2GHz Arm Cortex-R52 processors. Hardware isolation and virtualisation are provided to allow sharing of on-die hardware between different code blocks without interaction “to support the consolidation of cross-vehicle electronic control units in vehicle central compute applications”, said NXP. “Vehicle functions can be independently managed, including fault handling ...
