Vishay has extended its Automotive precision resistor range in 0402, 0603 and 0805 case sizes, which now rub up to 7.5MΩ with ±25ppm/K temperature resistance and ±0.1% tolerance. MCS 0402 AT, MCT 0603 AT and MCU 0805 AT offer values from 47Ω to 1 MΩ, 2MΩ and 7.5MΩ respectively. “They join the previously enhanced MCA 1206 AT, which offers resistance ...

Winner Paragraf – GHS, a Hall-effect sensor for mapping EV battery cells   The GHS01AT is believed to be the world’s only graphene Hall-effect sensor optimised for the characterisation and mapping of battery cell current in electric vehicles. The sensor provides direct measurement of current flow to identify and prevent the formation of hot spots that can lead to thermal ...

Diodes has introduced a driver for high-side and low-side mosfet gates in half-bridges up to 100V. Called DGD0579U, it is aimed at cordless power tools, e-bikes and autonomous robot appliances. “Mosfet protection mechanisms are integrated into the device, improving system reliability and optimizing board space,” according to the company. “These include cross-conduction prevention, so that the high-side and low-side mosfets are ...

Next year Panasonic plans to start mass production of a battery which will give a Tesla Model S a range of  750km – up from 650km at the moment. The new battery will have five times the capacity of the previous battery and will be twice as big and, costed on a capacity basis, be 10-20% cheaper. Mercedes’ EQS currently has ...

Toshiba has introduced a photo-relay capable of operating with 1.5kV across its output switch – the company’s first with such an output withstand voltage – “ensuring that it is compatible with the vast majority of traction batteries”, it said. AEC-Q101 qualified and aimed at battery management systems, TLX9160T consists of an infra-red emitting diode optically coupled to back-to-back photo-mosfets. Although intended ...

Toshiba has established a European high-voltage laboratory in Duesseldorf for automotive and industrial markets. “In line with the company’s shift in focus towards more power-related products, Toshiba invested this year in infrastructure and equipment such as high voltage power sources, loads and measuring equipment,” said Toshiba, The lab will will support European customers, particularly for silicon carbide and gallium nitride technologies used ...

Infineon has introduced a dual-channel smart gate driver for high-side load switches, design to control heavy loads in a 48 V board net through an SPI interface. Called 2ED4820-EM and ruggedised against vehicle transients, it can tolerate negative voltages at Vbat down to -90V and voltages up to +105V. Bus current sensing is included, with the amplifier compatible with both ...

Audi RS Q e-tron is a fuel-electric series hybrid made for the Dakar cross-desert race, which finishes today. In series hybrids, all drive is via electricity, there is no rotating mechanical link between heat engine and wheels. Just like a diesel-electric railway train, the intervening electric drive allows the fuel engine to run continuously at its most efficient operating point ...

Toshiba is sampling an Ethernet bridge IC – the TC9563XBG – for use in automotive zonal-architecture, infotainment, telematics or gateways as well as industrial equipment. Volume production is planned for April. The new bridge IC incorporates two 10 Gbps Ethernet Media Access Controller (MAC) supporting a number of interfaces including USXGMII, XFI, SGMII, and RGMII. Both ports support Ethernet IEEE802.1 ...

First samples of Infineon’s 28nm Aurix TC4x family of automotive MCUs are available. “The family provides an upward migration path for the Aurix TC3x family,” according to the company. “It features the next-generation TriCore 1.8 and the new parallel processing unit, a SIMD vector DSP which addresses the demands of various AI topologies – this may include real-time control and ...
