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 ...

Infineon has lined up a Rust programming language compiler for two of its TriCore architecture processor families: the existing TC3x and forthcoming TC4x. “Rust, with its unique memory safety features, has emerged as a viable complement or potential substitute for C/C++ in automotive software development,” according to the company. Working with Infineon, HighTec EDV-Systeme has released an ISO 26262 ASIL ...

TDK has announced automotive smart motor drivers that can handle 4 x 1A peak current and include an Arm Cortex-M3 processor core. HVC 5222D with 32kbyte of flash and HVC 5422D with 64kbyte can drive brushless dc, brushed dc (2A) and stepper motors. They also have 4kbyte ram, 2kbyte of emulated eeprom and 1kbyte of non-volatile registers, and are “SEooC ...

Automotive connectors play a crucial role in the circuitry of vehicles, as their dependability directly affects the overall functioning of the vehicle system. As the demands for automotive safety, environmental consciousness, comfort, and intelligence continue to increase, the requirements for automotive connector products have also intensified. These products now need to possess enhanced capabilities such as miniaturization, integration, resistance to ...
