STMicroelectronics has introduced stripped down versions of its STM32MP2 MCU family for smart factory applications. Called STM32MP21, they all get a single 1.2 or 1.5GHz Arm Cortex-A35 application processor and a single 300MHz Cortex-M33 for booting and sleep-wake control. Arm’s TrustZone is available for secure code separation, and ST’s proprietary ‘resource isolation framework’ (RIF) is present to defend against tampering. ...

Allegro MicroSystems has created a pair of ICs that transmit isolated control signals and power to silicon carbide mosfet gates. AHV85003 is the transmitter and AHV85043 is the receiver, which need to be connected together through an isolation transformer. “With selectable gate-to-source voltages of 15V, 18V and 20V, and adjustable regulated negative voltage, designers can swap between SiC FETs from ...

Finnish company Enedo Power has turned to GaN transistors to put a 1,200W ac-dc power supply into a 41 x 107 x 206mm (900cm3) volume. Called HDP1200, they run from 85 – 305Vac (de-rated to 1kW below 137Vac) and produce 24V or 48V depending on type, plus a 5V 1.5A stand-by output. Efficiency is up to 95.5%, and a fan ...

Cortec has improved the strength and tack of its Eco Wrap industrially compostable wrapping firm, it said. “Five years ago, Cortec introduced Eco Wrap, [a] blown film produced with certified compostable resin and a proprietary tackifier additive,” according to the company. The new version “is tackier and stronger than the previous iteration while remaining certified industrially compostable by TÜV Austria, ...

The 4Kp30 multi-sensor camera reference design is by Altera and designed for its Agilex 5 FPGAs. It uses industry-standard MIPI connectivity: D-PHY and MIPI CSI-2 for the FPGA interface and Altera’s FPGA AI tool for smart camera development to develop glass-to-glass edge vision for smart cameras, with real-time 4K AI interference. The MIPI interface supports up to 2.5Gbps per lane ...

Globalfoundries (GF) and onsemi have signed an agreement to develop and manufacture advanced GaN power products using GF’s 200mm eMode GaN-on-silicon process. The focus for initial development will be 650V power devices for AI datacentres, electric vehicles, renewable energy, industrial systems,  aerospace, defence and security. “This collaboration brings together onsemi’s system and product expertise with GlobalFoundries’ advanced GaN process to ...

TI has remained remarkably quiet about its latest precision voltage reference IC: REF81. It is a modified form of the equally quietly released REF80, which is a temperature-controlled buried Zener reference with 0.05ppm/°C drift and better than 1ppm stability. Its output is around 7.6V, and it is specified over 0 to +70°C. After 1,000 hours (and up to 5,000h), stability ...

Diodes has introduced a series of low saturation npn and pnp bipolar transistors optimised for automotive power switching and control. “With BVceo up to 100V, continuous current to 10A – and 20A peak – and saturation voltage as low as 17mV, these transistors minimise conduction losses,” according to the company. There are 12 devices, all in 3.3 x 3.3mm surface-mount ...

For brushed dc motors, Rohm has developed a pair of driver ICs. BD60210FV is for two 8 – 18V 1A motors (4A peak) and comes in a 5 x 6.4mm 16pad SSOP. It has a number of modes, including stand-by/forward/reverse over two wires, or stand-by/forward/reverse/brake over four wires, and as four half-bridges – to control a single two-phase stepper motor, ...

E-peas has announced an solar harvesting power management IC that can accept inputs from 5µA to 1A “spanning the full dynamic range of hybrid indoor-outdoor photo-voltaic cells”, it said. “These hybrid PV cells have a wide power output that can vary from microwatts under indoor lighting to several watts when in direct sunlight,” the company explained. With external components including ...
