Analogue / Linear / Mixed Signal ICs

Nexperia has introduced an inductor-less energy harvesting IC that is able to cold start with 12μW from 270mV. Called NEH7100BU, it can mediate between a harvesting power source, a USB charger, a battery (or capacitor) and the load. To maximise power extracted from photovoltaic cells, which have variable output impedance, and embedded hill-climbing algorithm homes-in on the best operating point ...

Toshiba is aiming vehicle body automation with it its latest three-phase motor diver. TB9084FTG, as it will be known “supports replacing brushed dc motors with quieter, longer-lasting BLDC motors to drive body system applications like powered sliding passenger doors, power tailgates, adjustable seats, electric pumps and fans”, it said. The IC is designed to control the gates of seven external ...

For the gate drivers of high-power IGBTs, mosfets, SiC mosfets and GaN hemts, Infineon has introduced an isolated power supply IC that can generate asymmetric output voltage rails. Each member of the 2EP1xxR family, as it will be known, has a full bridge of mosfets at its output for driving both ends of a transformer primary, whose secondary can be ...

  STMicroelectronics has designed a pair of rail-to-rail comparators that can be power cycled without dragging down circuits connected to their inputs. Both industrial and AEC-Q100 qualified automotive versions are available. For dependable use in power-saving applications where the power rail is periodically cut, they have a guaranteed maximum start-up time of 15μs. “Inspired by industrial robots that use sensors ...

Lumissil Microsystems is aiming at adaptive beam vehicle headlights with controller for dozens of power LEDs. It is for ‘matrix’ headlights, that have an array of close-packed power LEDs and projection optics that focus that any pattern on the array forwards from the vehicle – allowing headlights to produce arbitrary beam patterns – usually controlled by an on-board forward facing ...

ScioSense has launched a two-channel time-to-digital converter for lidar distance measurement. LTDC-X3, as it will be known, offers single-shot resolution of up to 20ps(rms). The chip has one ‘start’ input and two ‘stop’ inputs, and calculates the time differences between the start channel and the stop channels. “In typical lidar designs, the start will be triggered by the laser trigger, ...

Onsemi has installed a 65nm BCD (bipolar CMOS DMOS) process at its fab in East Fishkill, New York, on a line that can handle 300mm wafers. Called ‘Treo Platform’ it can produce ICs with rail voltage from 1V to 90V, and that work up to 175°C. “This provides the foundation for a range of power and sensing solutions,” according to the ...

Toshiba has got together with development board maker Mikroe to create a platform for its TB9M003FG automotive three-phase motor control and driver IC. AEC-Q100 Grade 0 qualified, the IC has a 32bit 40MHz Arm Cortex-M0 CPU and a vector co-processor  for sensorless vector control, as well as gate-drivers to control external n-channel mosfets. AEC-Q101 qualified mosfets are included on the ...

STMicroelectronics is aiming at healthcare wearables with an IC that senses bio-potentials and acceleration, and includes an AI processor and a finite state-machine for pedometer, step detection and step counting. “The machine-learning core and finite state machine enable product designers to implement simple decision trees for neural processing on the chip,” according to the company. “ST1VAFE3BX provides opportunities to extend ...

Toshiba has filled out its TCKE9 electronic fuse and voltage-clamping IC family with two products: TCKE903NL clamps its output between 3.64 and 4.1V and latches off after tripping – cycling the enable pad re-starts it TCKE905ANA clamps its output between 5.4 and 6V and auto-tries after tripping Although not regulators – they are designed to work fully-on – they voltage ...
