Infineon Technologies has launched an ultra-low resistance high-side switch in a 9.9 x 11.7 x 2.3mm surface-mount package. For automotive use on 12V circuits, the IC is “ISO 26262-ready for supporting the integrator in evaluation of hardware element according to ISO 26262:2018 Clause 8-13”, said the company. Called BTS50005-1LUA, its nominal on-resistance is 0.6mΩ (1.1mΩ max at 150°C) and carrying ...

For vehicle functional-safety applications, STMicroelectronics has combined hot-swap, soft-start and ideal-diode OR-ing in an IC intended to work with a pair of external n-channel mosfets over 4 to 65V. Called STPM801, “the ideal-diode controller drives an external mosfet replacing a Schottky diode conventionally used for reverse-input protection and output-voltage hold-up”, said ST. “When a reverse-voltage event occurs, in case of ...

Fraunhofer Institute for Microelectronic Circuits and Systems IMS has had a version of its 32bit AIRisc RISC-V microcontroller intellectual property certified by by TÜV SGS to the ISO 26262 ASIL-D automotive safety standard. Called AIRisc-Safety, it can now be licensed from the organisation, which also offers customised versions for asic and FPGA integration. “Certification means that industrial customers directly receive a ...

NXP has introduced real-time microcontrollers for automotive ECUs, certified to ISO/SAE 21434 for cybersecurity and ISO 26262 ASIL D for functional safety. Part of its S32 range, they are: S32Z for safety processing and domain/zonal control S32Z1 series (future) 4x Cortex-R52 S32Z2 series 8x Cortex-R52 S32E for electric vehicle control and actuation S32E2 series 8x Cortex-R52 E parts are essentially Z parts with a ...

STMicroelectronics has announced a microcontroller for electric vehicle on-board chargers, particularly those using silicon carbide power components. “Typical automotive MCUs in the market today cannot execute the charging-control algorithms at a rate that can support the higher SiC switching frequencies,” claimed ST. “Instead, additional DSP chips are needed specifically to handle the control loop.” The new parts are “automotive-qualified MCUs ...

Diodes has added diagnostics to two-wire Hall-effect switches to ready them for ISO 26262 automotive functional safety. “They monitor main device blocks, supply voltage and temperature, with a third lower current output state,” according to the company. “This enables them, as a ‘safety element out of context’ [SEooC] to support ISO 26262 functional safety system integrations.” Applications are foreseen in automotive ...

Microchip has introduced versions of its MPLAB XC compilers certified for functional safety by TÜV SÜD, with the aim of simplifying the certification of customer projects built around PIC, AVR, SAM and dsPIC processors. “XC functional compilers certified by TÜV SÜD aid in satisfying the verification and validation requirements specified in the ISO 26262 standard for automotive safety, IEC 61508 ...

UK-based Imagination Technologies is aiming at in-car graphics and automated driving, with GPU intellectual property designed to achieve ISO 26262 qualification. For customers seeking such qualification, Imagination is backing the IP with additional investment “in the people, resources, culture and management structure needed to support automotive solutions,” company marketing director Bryce Johnson told Electronics Weekly. “Our testing, documentation and built-in hardware ...

Renesas has introduced a safety analysis tool intended to ease the integration of the firm’s products into safety-critical automotive systems “while increasing user confidence in system compliance to the latest safety standard”, it said. The failure mode effects and diagnostics analysis (FMEDA) software is optimized for ISO 26262, which addresses safety of electrical and electronic systems within road vehicles. It, said ...
