To get the best out of GaN power transistors, which are far faster than silicon or silicon carbide transistors, microwave design techniques including RF simulation is essential, according to Cambridge start-up QPT. Final assembly, EMC screen partially lifted The alternative is to slow operation until the advantages of GaN fade away, or to risk durability as unseen ultra-fast overshoot and ...

Battery maker Exide Technologies has switched to silicon carbide transistors for a 7kW industrial electric vehicle charger. Its chargers convert 220Vac to between 24 and 80V for lead-acid and lithium-ion powered vehicles. The 7 kW unit uses 750V mosfets (G3R60MT07D) and 1.2kV Schottky diodes (GD10MPS12A) from Navitas, and the same SiC platform is good for 10kW, and could be paralleled ...

Toshiba is aiming at over-temperature detection in mobile devices and home appliances with a family of ICs, intended to work with positive coefficient thermistors. Power consumption is under 12μA with 10μA of that going through the thermistor as sensing current. Lower current (<2μA) versions are planned. Inside is a current source to feed the PTC and a reference voltage with ...

ST is offering SESIP Level 3 security certification in 64bit microprocessors aimed at industry-4.0, with industrial interfaces and edge AI acceleration. Called the STM32MP2 series, these are the first 64bit STM32 ICs (all before are 32bit), and the first of this series will be the STM32MP25, available with single or dual 1.5GHz 64bit Arm Cortex-A35 cores (up to 6,000 DMIPS), ...

Advantech is aiming at industrial AI with a computer that combines a 12th Gen Intel Core (i9, i7, i5 or i3) CPU with Nvidia’s L4 GPU. Two slim doors provide access for the company’s Flex I/O expansion boards Called MIC-770 V3, “this industrial edge solution is boasts 7,424 Cuda cores and 30.3Tflop/s with 24Gbyte GDDR6 GPU memory in a 72W ...

Two new industrial communications products from Brainboxes will be on the Farnell stand at the National Manufacturing Supply Chain Exhibition in Dublin. PE-505 is a 55 x 55 x 10mm five-port 10 and 100Mbit/s (10BASE-T/100BASE-T) isolated (1.5kV) Ethernet switch PCB with non-blocking layer 2 operation, that can be built into equipment. Operation is from 3.3V (1.3W) or 4.5 – 12V ...

P-Duke has announced ultra-wide input isolated 40W dc-dc converters for railway and industrial use. RED40-72xxxU converter will work over 14 – 160Vdc (11:1 range) and comes in a 2 x 1in (~25 x 50mm) footprint package. “Using just one dc-dc converter model for various supply voltages – 24, 28, 36, 48, 72, 96 or 110Vdc – in different regions avoids ...

EPC is aiming at eMobility, forklifts and high-power drones with a 150Arms brushless motor driver design using its GaN power transistors. Documents for EPC9186, as it will be known, are not available yet, but the company promises operation from 14V to 80V for “applications such as electric scooters, small electric vehicles and agricultural machinery” in addition to the items above. ...

Texas Instruments has releases an RS-485 transceiver that can be pin-programmed to suit networks with different bus voltage, logic voltage, network length and throughput. Called THVD1424, it includes switchable on-chip 120Ω termination resistor, slew rate control, and both half-duplex (two-wire) and duplex (four-wire) modes – allowing a single PCB type to be created that can be software re-configured for different ...

TDK-Lambda has introduced a series of rugged non-isolated 300W buck-boost dc-dc converters. The RGC series has a 9 to 53V imput range and adjustable output voltages of 9.6 to 48V (8Amax), or 5 to 28V (12.5Amax), depending on version. The idea is to cover 12, 18, 24, 36 and 48V batteries and power sources. Remote shut-down reduces input current to ...
