Analogue / Linear / Mixed Signal ICs

TI announced a co-packaged 650V GaN half bridge and driver at APEC in Florida this week, intended for use in active-clamp fly-back dc-dc converters delivering less that 75W. Called LMG2610, the IC includes a pair of GaN transistors in a half-bridge, gate drivers, a bootstrap diode and a high-side gate-drive level shifter, all in a  9 x 7mm QFN package. ...

Power Integrations is aiming at industrial and automotive power supplies up to 100W, by building 900V GaN transistors into its InnoSwitch3 fly-back switcher family – something it announced at APEC in Florida. Previously 750V was the highest rating amongst the GaN members of this family. There are two product lines now with 900V gallium nitride options: The AEC-Q100-qualified InnoSwitch3-AQ family ...

Rohm has announced a high-side current sensor with a -0.2 to +26V input common-mode range and ±1.0% maximum gain error. Packaged in a 2.9 x 2.8 x 1.25mm SSOP6, BD14210G-LA senses voltage across an external high-side resistor and transfers this to a voltage relative to the 0V rail with a fixed gain of 20. Max offset is ±0.6mV (refered to ...

While the global semiconductor industry is in turmoil these days, one Japanese company is rapidly increasing its presence in the industry, under strong leadership. That company is ABLIC Inc., an analog semiconductor specialist. Its uniqueness stems from the fact that in its early beginnings before it was named ‘ABLIC’, the company’s specialized craftsmanship was born in the semiconductor department of ...

Analogue devices has created a fast-responding low-noise low drop-out linear regulator, digitally-programmable to output various voltages between 500mV and 4.2V at up to 3A. Input range is 600mV to 5.5V. Dubbed LT3073, its output, set through three tri-level pads, can be: in 50mV increments from 500mV to 1.2V, in 100mV increments from 1.2 to 1.8V, and then 2, 2.5, 3, ...

February is definitely the month for automotive high and low-side drivers, proved beyond doubt as Diodes has just followed Rohm, Toshiba and STMicroelectronics with its contribution: a protected 4A (25A pulsed) high-side switch. Called ZXMS81045SPQ, it operates across 5 – 28V (41V abs max) and responds to both 5V and 3.3V logic inputs. Packaging is SO-8 with an exposed heat sinking ...

Micro Crystal has introduced a ±1°C temperature sensor that includes a real-time clock, draws only 160nA (3V), and is automotive-approved. Called RV-3032-C7, it comes in an hermetically sealed reflow solderable 3.2 x 1.5 x 0.8mm ceramic SON-8 package – which is Pb-free, RoHS compliant and AEC-Q200 qualified. It is actually a module, as the company, a division of Swatch, has ...

It seems to be the week for high and low-side driver announcements, with STMicroelectronics now following on from Toshiba and Rohm. ST’s offering are, like Rohm’s, for automotive use. They are single, double and quad high-side gate drivers in a common 6 x 4.9 x 1.7mm gull-wing thermal pad package, “with pin assignments that simplify scaling circuit designs to add ...

Rohm has released one and two channel 40V low-side switches with AEC-Q100 qualification for automotive and industrial use. BV1LExxxEFJ-C (single-channel, 4.9 x 6 x 1mm HTSOP-J8) and BM2LExxxFJ-C (dual-channel, 4.9 x 6 x 1.65mm SOP-J8) “are suitable for systems such as car body control, engine and transmission control units, LED lighting modules or industrial programmable logic controllers”, according to the ...

Toshiba has created octal high-side and low-side protected load drivers in SSOP30 packaging (9.7 x 7.6 x 1.2mm, 0.65mm pitch). The company is promoting them as smaller alternatives to SSOP24 packaged drivers like TPD2005F and TPD2007F. The new parts use the company’s latest analogue process which is BiCD – combining bipolar, CMOS and DMOS elements. The high-side switching TPD2015FN (right) ...
