Analogue / Linear / Mixed Signal ICs

Toshiba is aiming at air conditioners, air purifiers and pumps with an IGBT-based brush-less dc motor driver, suitable for sine-wave generation, in a ~13 x 33mm through-hole HDIP30 package. TPD4165K, as it will be know, can handle a maximum output of 3A, compared with 2A for the company’s earlier TPD4163K or TPD4164K. Absolute maximum input voltage has been raised to ...

It seems to be Ideal Diode Week at Electronics Weekly (here and here) as Diodes is also promoting one, this time an ideal diode that can cope with ±65V on its input and drops only 20mV when conducting. The automotive-compliant AP74700Q operates down to 3.2V (or 3.9V at start-up) to allow for cold cranking of a vehicle engine. Inside, a ...

Nexperia has put an ideal diode, including its p-channel mosfet, and reverse polarity protection, in a 2.1 x 1.25 x 0.95mm TSSOP6 package. Called NID5100, it is aimed at industrial and consumer applications, and has an automotive-qualified cousin named NID5100-Q100. “NID5100 supports ‘OR-ing’ multiple power supplies while retaining reverse polarity protection and provides fast response time for smooth power transfer,” ...

Infineon has introduced six automotive linear regulators, protected against 40 or 45V, and supplying 3.3 or 5V at up 500mA, some with enable, watchdog or reset circuits (see the table below). Picking the TLS820F3ELV50 as an example, it has an input range of 3 to 42V (45V abs max) and outputs 5V ±2% at up to 200mA. “These regulators are ...

Infineon Technologies is to integrate 600 and 700V GaN power hemts alongside gate driver chips inside single packages, in 5 x 6mm or 6 x 8mm SMD packages. IGI70NxxxA2xS is to be a 700V range that combines a single GaN transistor with a single-channel driver in 5 x 6mm PQFN with with 140 to 500mΩ options (IGI70NxxxA2PS), or 6 x ...

Lumissil Microsystems has created a pair of LED drivers that include a 32MHz 8051 microcontroller. “These new controllers enable lighting engineers to create customised dynamic LED lighting animations tailored to their system requirements,” according to the company. “They feature integrated non-volatile memory to store animation sequences and LED parameters, essential for dynamic lighting effects such as colour transitions, pulsing, fading ...

Nexperia has created a pair of 17mΩ 13.5A resettable electronic fuses for 12V hot-swap applications in 3 x 3 x 0.75mm DFN3030-10 (SOT8037-1) packaging. NPS3102A and NPS3102B operate with 9 to 18V on the input (21V abs. max) and can limit output current to anywhere between 2 and 13.5A range, programmed using a resistor – the voltage across which can ...

Senseeker has introduced a 1,280 x 1,024 version of its 10µm digital read-out IC (‘droic’) for short-wave infra-red imaging arrays, including quantum dot-based detector types. RD0131 as it will be known has a capacitive transimpedance amplifier (CTIA) front-end. There are three selectable gains, with well capacity of: 22k electrons (high-gain), 160ke- (medium) or 1.1Me- (low). In high gain, room temperature ...

Würth Elektronik has created a range of opto-isilated triacs for controlling light AC loads and larger triacs. They are called WL-OCTR, and come in a choice of packages: through hole DIP-4 or DIP-6, or surface-mount SOP-4. Through-hole parts offer 5kV breakdown between input and output, which drops to 3.75kC for surface mount. DIP parts can also be supplied with legs ...

At DAC 2024, Efabless celebrated a milestone of 40 commercial companies designed chips using its chipIgnite and Google-sponsored OpenMPW programme. Of these, some are ready for production volumes, the majority are at the prototype/proof of concept stage, said CEO, Michael Wishart. The platform allows start-ups and smaller companies to prototype designs and innovate without having to buy a license, he ...
