Vishay has introduced a photovoltaic mosfet gate driver qualified to AEC-Q102 for automotive use. Called VOMDA1271, “the component is available in a SOP-4 housing. The driver is the only one of its kind in this package size with an isolation voltage of 3.750 V [sic] and a typical open-circuit output voltage of 8.5V”, according to component distributor Rutronik, which is ...

Toshiba has added over-temperature and over-voltage protection features to an 80V 1.4A photo-relay, all inside a 4pin DIP package. Called TLP241BP, it can switch ac or dc though its single isolate 280mΩ (max) output switch – implemented as a pair of back to back mosfets – and handle pulses up to 4.2A (100ms, 1/10 duty). Output leakage is 1μA max ...

I really like this one, the waxing and waning. It's described as a Moon phase device, which models the aspects of our satellite orb.

“Car headlights should be better regulated to reduce the dazzle they cause on-coming drivers”, according to a report produced by Scottish charity Lightaware. Called ‘Modern vehicle headlights dazzle drivers and may compromise road safety’, it highlights the extra-sharp sharp angular transition between the brightest part and the dim ‘cut-off’ of dipped headlight beams made possible by technologies such as LED ...

Polish distributor, TME, has signed a distribution agreement with US optoelectronic component manufacturer, Inolux. Stock items include surface mount, through hole and IR leds. Surface mount coloured light emitting devices for indicators or beacons make up the largest part of the range. There are also white leds, rated up to 0.1W, with viewing ranges from a well focused beam (20°) ...

The AEC-200 Y2 class interference suppressor capacitors by Cornell Dubilier that meet a 2,000 hour THB (temperature, humidity and bias) life test are available from New Yorker Electronics. The MYH series were subjected to 2,000 hours THB testing at 85°C, 85% relative humidity at rated voltage, which is twice the industry standard test hours required to meet IEC 60834, Class ...

A new reference design by Vishay, and available from DigiKey, uses its eFuse resettable fuse with TrenchFET mosfets. It is designed for projects where semiconductor-based resettable fuses replace mechanical relays and traditional (non-resttable) fuses. Typical design applications will be 48V e-mobility projects – battery management systems, EV testing and solar installations as well as industrial and home automation, industrial and ...

Bourns has added 20 Multifuse polymer PTC resettable fuses in 1206 packages to its circuit protection portfolio, the Model MF-NSMF series. The new higher power rated fuses provide expanded over current/over temperature protection selection options in the compact 1206 footprint to save board real estate or to reduce design size and costs. The latest additions to the portfolio use the ...

Nisshinbo Micro Devices  has launched a Voltage Tracker for automotive applications including ECU, body  equipment and power supply for off-board sensors. Voltage Trackers are useful as a buffer power supply, where a reference supply voltage is replicated with high tracking accuracy and the safety level of the electronic system is generally increased. The NJW4250 voltage tracker operates up to an ...

There are two sensor choices, reed and Hall-effect switches. They have many similarities but also significant differences, explains Martin Reizner. Demand for reed switches has risen significantly in the recent past. This is primarily due to their mechanical structure, which reduces energy consumption to zero when the switch is in a passive state. That is why reed switches are an ...
