Analogue / Linear / Mixed Signal ICs

Renesas has introduced a four-channel IO-Link master for the industrial IO-Link bus, and a dual-channel resistive sensor signal conditioner. “IO-Link has become increasingly popular in recent years due to its ability to provide real-time data and diagnostics, and its compatibility with existing systems,” said Renesas, adding that it also offers remote configuration and monitoring. CCE4511 is the four-channel IO-Link master, ...

Infineon has created a fast-disconnecting 125V load switch for fault protection in cordless power tools, e-bikes, battery-powered robots and battery vacuum cleaners. Packaged in a 5 x 6mm DSO-8, 1EDL8011 includes a charge-pump to drive the gate of the external high-side n-channel mosfet that does the switching. There are actually two charge pumps: a high-capacity on using the external capacitor ...

Vishay has introduced a 1 Form A solid-state relay with AEC-Q102 qualification and a 100V load voltage, claiming it to be industry’s first. Packaged in low-profile SOP-4 package (5 x 7 x 2.2mm), VORA1010M4 typically turns on and off in 100μs, and operates up to +125°C. “The fast turn-off time is a result of its integrated turn-off circuit, while its ...

Toshiba has created a pair of 32Gbit/s multiplexer/demultiplexer switches, intended to switch two differential pair signal paths, or four single-ended signal paths, between a single port on one side and two ports on the other. The devices are aimed at high speed serial busses including PCIe 5.0/4.0, CXL 2.0/1.0,  USB4 Version 2.0, Gen3/Gen2, USB 3.2 Gen 2/Gen 1,  Thunderbolt 4, ...

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 ...

Allegro MicroSystems had introduced 1MHz bandwidth current sensors that can measure hundreds of amps – the first fruit of its acquisition of Crocus Technologies. The technology is tunneling magnetoresistance, and the sensors are intended to sit over the current-carrying PCB track to be measured. Output is a voltage linearly proportional to the current, responding within 300ns. There are two base ...

NXP has combined short-range 6 – 8.5GHz UWB radar, secure ranging and angle-of-arrival processing on a single chip. Called SR250, it is for “a world that anticipates and automates, enabling a variety of new user experiences based on location, presence or motion detection across consumer or industrial IoT applications”, claimed the company. It is said to support 3D angle-of-arrival and ...

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, ...

Distributor Rutronik has added three surface-mount RTK-enhanced GNSS modules from Unicore to its portfolio. RTK – ‘real time kinematics’ – is a service that increases the accuracy of satellite navigation systems. UM982 GPS L1/L2/L5 BDS B1I/B2I/B3I GLONASS G1/G2 Galileo E1/E5a/E5b QZSS L1/L2/L5 SBAS 16 x 21 x 2.6mm UM980 BDS B1I/B2I/B3I/B1C/B2a/B2b GPS L1/L2/L5 GLONASS L1/L2 Galileo E1/E5a/E5b QZSS L1/L2/L5 SBAS ...

Diodes has introduced a 12-channel constant-current LED driver arranged as four channels of RGB. AL58221 has open-drain outputs that can sink up to 60mA and withstand 24V. Maximum red green and blue currents are set with three resistors, then the individual channels are digitally-modulated to set their brightness. To reduce flicker, adaptive pulse density modulation is used, with diodes claiming ...
