AEC-Q200 transformer isolates battery management signals

bourns SM91872AL automotive transformer

Bourns has created an AEC-Q200 compliant 1:1 signal isolation transformer for automotive battery management systems. SM91872AL is surface-mount and will fit into a 17.4 x 10.6 x 8.1 envelope – including its visible legs. Inductance is 150 to 450µH (100kHz 100mV) across its -40 to +125°C operation range, and leakage inductance is 1µH max. Both sides have a maximum resistance ...

Automotive CXPI interface has GPIO, ADC and PWMs

Toshiba VQFN package

Toshiba is developing an interface IC for the automotive CXPI (clock extension peripheral interface) bus whose hardware logic “can control data communication by CXPI protocol and GPIO, eliminating the need for dedicated software development”, according to the company. Not a lot more has been revealed about the function of the IC, called TB9033FTG, except that it has 16 GPIO pins, ...

Protection diode for OPEN Alliance 100Base-T1 and 1000Base-T1

Vishay Ethernet ESD diodes

VETH100A1DD1 is a bidirectional ESD protection diode for automotive Ethernet, compliant with OPEN Alliance 100Base-T1 and 1000Base-T1. Made by Vishay, it comes in a wettable flank DFN1006-2B package  measuring 1 x 0.6 x 0.45mm. Working range is ±24V, and clamping is typically at 31V for 1A, “a result of its snap-back technology with a trigger voltage >100V”, said the company. ...

SMD resistors to AEC-Q200

Bourns-CRT-A-automotive-smd-resistors

Bourns has created a surface-mount thin-film resistor series with AEC-Q200 compliance for automotive use. Model CRT-A resistors are available with tolerance of ±0.1, ±0.25, ±0.5 or ±1%, and temperature coefficients of ±50, ±25, ±15 or ±10ppm/°C. These compact, yet high power-rated resistors offering accurate resistance levels are increasingly required in space-constrained applications such as mobile phones, SD cards, DDR memory ...

Automotive voltage regulator with reset and watchdog

Infineon TLS820F3ELV50 linear regulator

Infineon has introduced six automotive linear regulators, protected against 40 or 45V, and supplying 3.3 or 5V at up 500mA, some with enable, watchdog or reset circuits (see the table below). Picking the TLS820F3ELV50 as an example, it has an input range of 3 to 42V (45V abs max) and outputs 5V ±2% at up to 200mA. “These regulators are ...

Single-pair Ethernet tranceivers suite automotive links up to 40m

Microchip LAN887x single pair ethernet transceiver

Microchip is aiming at automotive single-pair Ethernet links up to 40m long with a 7 x 7mm transceiver ICs called LAN8870B. Single-pair Ethernet is also being used in avionics, robotics and automation, it said. “For interoperability across industries, LAN887x PHYs are designed to be compliant with IEEE 802.3bp for the 1000BASE-T1 specification, and IEEE 802bw-2015 for the 100BASE-T1 specification*,” according ...

Video: Siemens EDA on software defined vehicles, V2X, AI, and security

EW-SIEMENS-160724-V2-thumb-300x200.jpg

Lee Harrison, Director, Product Marketing at Siemens EDA covers trends in the testing market, software defined vehicles, V2X, security, and advanced automotive hardware, such as multi-die chips to help scale complexity in a cost-effective way. He also talks AI and the use of SSN (streaming scanned networks) and why it represents a once in a decade testing technology. Note that ...

Intel’s discrete GPU for vehicle cockpits

Intel discrete automotive graphics IC

Intel has announced a discrete graphics processing unit, aimed at vehicles being shipped in 2025. ‘Arc Graphics for Automotive’, or A760A, has 28 of the company’s Xe GPU cores, 28 ray tracing units, 448 matrix engines (XMX) for AI and 448 vector engines. It will be software-compatible with the GPUs integrated into its software-defined-vehicle processors, and used as an add-on ...

Considerations when designing chips for automotive use

Sondrel-1-300x200.jpg

Challenges faced by automotive chip designers include longer than average expected lifespans and rigorous functional safety standards, explains Paul Martin. The expected lifetime for the vast majority of chips is typically a few years, but chips for automotive use have an expected lifespan of 10 to 15 years, to match the lifespan of the average car, and a supply lifetime ...

LED drivers for animated effects

IS3xCS8979 led driver block

Lumissil Microsystems has created a pair of LED drivers that include a 32MHz 8051 microcontroller. “These new controllers enable lighting engineers to create customised dynamic LED lighting animations tailored to their system requirements,” according to the company. “They feature integrated non-volatile memory to store animation sequences and LED parameters, essential for dynamic lighting effects such as colour transitions, pulsing, fading ...
