NXP is aiming at ASIL D safety approval with a vehicle battery junction box controller IC, intended to fire the pyrotechnic disconnect switch during a serious fault, as well as report faults over a serial bus. MC33777A, as it will be known, redundantly measures currents, voltages and temperatures, then deduces situations – a short circuit or a crash, for example ...

Nexperia has put more single and dual small-signal mosfets into DFN1110D-3 (SOT8015) and DFN1412-6 (SOT1268) packages, with side-wettable flanks for automated optical inspection. “The 1.1 x 1mm DFN1110D-3 package has seen increasingly wide adoption, and is quickly becoming the de-facto industry standard package for small-signal mosfets and bipolar transistors intended for use in automotive applications,” according to the company. “Superior ...

TDK has introduced a series of high-value metal-framed multi-chip ceramic capacitors for automotive electric power trains, on-board chargers and wireless power transfer systems, where the capacitors must handle high currents or voltages, or have high capacity. “To meet these needs, TDK developed the CA series, the largest MLCCs in the industry [6 x 5.6 x 6.4mm] with a metal frame ...

Magnachip has come up with four new 40V MXT MV MOSFETs designed in PDFN 33 packages for automotive applications. PDFN33 packages reduce footprint by more than 60% and the weight by approximately 75% compared to PDFN56. Three of the devices – AMDV040N029LVRH, AMDV040N036LVRH, and AMDV040N042LVRH – have a gate threshold voltage of 1.8V. Magnachip’s New Automotive 40V MXT MV MOSFETs The key ...

Vishay has added five solenoid-based haptic actuators to its IHPT range, which come with operation licenses from Immersion Corporation. There are four sizes, from 29 x 21mm to 44 x 37mm, that can provide forces up to 120N. Not immediately obvious from the photo, each transducer us in two parts: the top left part is a separate laminated metal bar ...

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, ...

Nexperia has announced 20 bipolar power transistors in 2 x 2mm DFN2020D-3 packaging, half of them automotive-qualified. The span 50 and 80V ratings, 1 to 3A currents and both npn and pnp polarities. “DFN2020D-3 packaged devices deliver an 80% reduction in board space when compared to SOT89, and a 90% reduction compared to SOT223,” according to the company. “The package ...

Q2 sales of  EVs – including battery, hybrid and fuel cell vehicles – were up nearly 30% q-o-q and 24.2% y-o-y at 3.769 million units, says TrendForce. Battery EV (BEV) salesreached 2.328 million units in 2Q24, an 8% YoY growth. Tesla, the market leader, saw a 4.7% decline in sales y-o-y. BYD (excluding Denza) ranked second, with BEV sales growing ...

It seems to be Ideal Diode Week at Electronics Weekly (here and here) as Diodes is also promoting one, this time an ideal diode that can cope with ±65V on its input and drops only 20mV when conducting. The automotive-compliant AP74700Q operates down to 3.2V (or 3.9V at start-up) to allow for cold cranking of a vehicle engine. Inside, a ...

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 ...
