Analogue / Linear / Mixed Signal ICs

Dialog has automotive-qualified one of its GreenPak family of one-time-programmable chips with multiple analogue and digital functions – intending it to replace multiple devices in navigation, infotainment and driver assistance systems, as well as display clusters and body electronics. Called SLG46620-A, it comes in a 6.4 x 6.5mm TSSOP-20 and is AEC-Q100 Grade 2. “In today’s automotive market, manufacturers are required to ...

Renesas has announced its fourth-generation lithium-ion battery management IC for electric vehicles – promising “unmatched lifetime accuracy”, which it quantifies as ±6mV (at ±6σ) 15-year board level accuracy. Called ISL78714, the chip monitors and balances up to 14 series connected cells with initial ±2mV accuracy (14bit ADC) across 1.65V to 4.28V and -20ºC to +85ºC, which drops to ±2.5mV post board ...

Toshiba Electronics has announced the launch of a sensorless control pre-driver IC for brushless DC (BLDC) motors used in industrial and automotive applications. The main applications will include electric pumps for water, oil and fuel as well as electric fans. The TB9062FNG pre-driver can control BLDC motors using a simple pulse-width modulation (PWM) input, without the need for high-performance MCUs ...

UnitedDS Semiconductor (UDS), UMC’s design affiliate, and Taiwan design house TeraSillC are shipping 24GHz radar transceiver ICs reports made on UMC’s low-power CMOS process, reports DigitTimes. Called  Orthrus, the chips come in 1T1R (one transmitter one receiver) and 1T2R specs. TeraSillC’s CTO S. A. You says the Orthrus radar transceiver integrates all the sub-systems required by high-performance radar system and ...

Teledyne e2v and Logic-X have developed an FPGA mezzanine card incorporating GHz ADCs and DACs from Telydyne. The 12bit EV12DS460A DAC provides an analogue bandwidth extending beyond 7GHz “facilitating multi-band, direct digital synthesis up to 26.5GHz K-band with a latency of three clock cycles”, according to Logic-X. The 12bit EV12AS350B ADC combines 5.4Gsample/s, an input bandwidth over 4.8GHz, latency as ...

Maxim has introduced a bi-directional current sense amplifier with pulse-width modulation (PWM) edge rejection. Called MAX40056 it is intended to reduce vibration in motor drives. The claim is that it can reject PWM slew rates of >500V/µs and settles within 500ns to provide a 0.3% accurate (of full-scale) measurement of winding current “allowing motor control designers to increase drive frequency ...

TI has introduced an automotive system basis chip which integrates a controller and transceiver for Controller Area Network with Flexible Data Rate (CAN FD). Designed to meet the high-bandwidth and data-rate flexibility needs of in-vehicle networks, the TCAN4550-Q1 uses the Serial Peripheral Interface (SPI) bus of almost any microcontroller to implement, with minimal hardware changes, a CAN FD interface or ...

Believed to be one of the first devices to support Bluetooth Core 5.1, Nordic Semiconductor’s nRF52811 SoC is now available from Rutronik UK The Bluetooth Core 5.1 specification was introduced early this year and adds tracking and location functions. The nRF52811 is a multi-protocol SoC that supports IEEE 802.15.4 for Thread and ZigBee and also Bluetooth Direction Finding and Bluetooth Long Range for direction ...

Texas Instruments has revealed the fastest 12bit ADC – the ADC12DJ5200RF – that can sample two channels at 5.2Gsample/s, that can be interleaved into a single 10.4Gsample/s channel. That is two channels of 12bit 2.6GHz instantaneous bandwidth, or one of 5.2GHz instantaneous bandwidth. “The design comes from our centre in Friesing Germany – they have been designing high-speed ADCs there for ...

Cissoid has announced an adjustable linear regulator and logic gates that operate with junction temperature from -55°C up to 175°C – exceeding AEC-Q100 Grade 0 standard, the Belgian high-rel chip maker pointed out. Members of the firm’s new CXT series of automotive grade components, all with the same temperature range, the first is CXT-STA4919, a 50mA adjustable linear voltage regulator that can create ...
