Analogue / Linear / Mixed Signal ICs

STMicroelectronics has combined two LDOs, a CAN FD transceiver, four PWM-able high-side switches, a watchdog timer and a LIN transceiver into a single automotive-grade power IC. Called SPSB081, its aim is to provide a companion microcontroller with power, two serial interface transceivers, battery-voltage high-side load drivers and power for its peripherals. There are four devices giving 5V or 3.3V from ...

Texas Instruments has announced a 220V (or ±110V) analogue switch with 16 channel of single-throw switching. It has logic-level (1.8 to 5V) control inputs, with thresholds set by the separate 1.7 to 5.5V logic supply, and needs at least 40V across its switch supply pins (0V and +40V, or ±20V, for example) to operate. Absolute max for the controlled signal ...

SiTime has used MEMS instead of quartz crystals to make an oven-controlled oscillator with ±1ppb frequency stability and ±0.02ppb/°C frequency slope – all on a 9 x 7 footprint, including the oven. “No further thermal precautions are needed, additional covers are not needed,” the company told Electronics Weekly. “The physical footprint is 9 x 7 x 3.73mm, and the device ...

Texas Instruments has added an analogue version of the non-optical replacement for digital opto-isolators it just revealed. Called ‘opto-emulators’, both analogue and digital versions replace the LED and photo-diode or photo-transistor within a conventional opto-isolator with an SiO2 barrier across which the a modulated version of the input signal is passed – probably magnetically (Electronics Weekly has requested clarification). The ...

Unleash the Power of Innovation with Industrial Semiconductors from Profusion Ltd. Profusion Ltd is a specialist semiconductor distributor that has supplied the audio industry for nearly 35 years, forging close ties with global partners who design and manufacture a wide range of state-of-the-art components. Many of these parts have a much broader application base than audio, with considerable potential for ...

Toshiba has released the promised expansion of its TCTH0xxxE multi-point over-temperature alarm IC family. Each of these simple ICs, (branded ‘Thermoflagger’) works with one or more PTC (positive temperature coefficient) thermistors to detect over temperature across a PCB, for example, perhaps sensing the individual temperatures of multiple power mosfets . “With safety paramount in many applications, the over-temperature detection ICs ...

Navitas recently announced its fourth generation of GaN power transistors with monolithically-integrated gate drivers. Branded GaNsafe, the company has increased the protection integrated alongside the driver and has moved to 10 x 10mm TOLL packaging, with a custom internal leadframe (diagram below). The initial products are rated at 650V (800V transients), cover Rds(on) from 35 to 98mΩ (table below), and ...

Diodes has released a 3A low-dropout low-noise voltage regulator. Called AP7179D, it has ±1% output accuracy (Vin = Vout + 300mV) across line, load and temperature, according to the company, and it drops 180mV (maximum) with 3A of load. Its low-noise reference and error amplifier contribute to 4.4µVrms typical operation at 800mV output (7μVrms at 5V), and PSSR (power supply ...

E-peas has created a power IC that can mediate between two energy harvesters, a 5V charger, a power store and a load. AEM13920 can work from any combination of two sources including: photo-voltaic cells, thermo-electric generators, RF energy harvesters or kinetic pulsed sources. “For instance, a remote control could have separate PV cells on its front and rear, to maintain ...

Rohm has developed Hall-based magnetic detectors for vehicle use. BD5310xG-CZ types are momentary (dubbed ‘unipolar’): turning on above a fixed south pole magnetic flux density and turning off below the same threshold (with a small amount of hysteresis) BD5410xG-CZ types are latching: turning on above a fixed south pole flux density, then remaining on until an equal north pole flux ...
