Analogue / Linear / Mixed Signal ICs

Infineon Technologies has launched an ultra-low resistance high-side switch in a 9.9 x 11.7 x 2.3mm surface-mount package. For automotive use on 12V circuits, the IC is “ISO 26262-ready for supporting the integrator in evaluation of hardware element according to ISO 26262:2018 Clause 8-13”, said the company. Called BTS50005-1LUA, its nominal on-resistance is 0.6mΩ (1.1mΩ max at 150°C) and carrying ...

Texas Instruments has created a series of precision current monitors with digital outputs, for use across power rails from  -100mV to +85V, at up to ±78.64A. In each case, an internal ΣΔ ADC measures current across an integrated sensing resistor, as well as voltage and temperature – communication with the host if via I2C. The ICs need a separate supply ...

STMicroelectronics has created its first galvanically isolated gate driver for GaN transistors. Called STGAP2GS the wide body SO-8W packaged single-channel driver can work with rails up to 1.2kV. The package is 5.8mm long by 10.3mm across pins tips, with 7.5mm between leg roots on either side of the isolation barrier. A separate supply (above), or dual supplies (left) if a ...

Diodes has created a range of precision current shunt monitors that have a -0.3 to 26V common-mode sense range irrespective of supply voltage, allowing both high-side and low-side measurement – and a reference pin is provided for bi-directional current measurement. Called the ZXCT21xQ family, there are six gain options: 50V/V  ZXCT213Q 75V/V  ZXCT215Q 100V/V  ZXCT214Q 200V/V  ZXCT210Q 500V/V  ZXCT211Q 1kV/V  ...

For vehicle functional-safety applications, STMicroelectronics has combined hot-swap, soft-start and ideal-diode OR-ing in an IC intended to work with a pair of external n-channel mosfets over 4 to 65V. Called STPM801, “the ideal-diode controller drives an external mosfet replacing a Schottky diode conventionally used for reverse-input protection and output-voltage hold-up”, said ST. “When a reverse-voltage event occurs, in case of ...

Analog Devices has released some details of a 10GHz bandwidth analogue front-end, possibly to be revealed in full at IMS in San Diego this week. The 16nm CMOS device is said to have four 12bit 20Gsample/s ADCs and four 16bit 28Gsample/s DACs – and seems like a faster cousin of the 28nm AD9081 released a few years ago – if ...

The OPAx992-Q1 family of 40V rail-to-rail op-amps from Texas Instruments are AEC-Q100 qualified for automotive use. There are single (OPA992-Q1), dual (OPA2992-Q1) and quad (OPA4992-Q1) versions. Intended to be general purpose, the amplifiers’ differential and common-mode input ranges reach the supply rails. 115dB common-mode rejection is claimed, and the devices are rated to be used as comparators as well as ...

Microchip has created a set of dual-channel single-lane USB 3.2 Gen1 SuperSpeed reclocker redriver ICs for automotive and industrial cables up to 15m long. “Adding electronic components to applications across automotive, industrial and consumer industries has spurred the need for far-reaching USB cabling products,” according to the company. EQCO510 is the automotive version, qualified to AEC-Q100 Grade 2 and operates ...

Toshiba is aiming at over-temperature detection in mobile devices and home appliances with a family of ICs, intended to work with positive coefficient thermistors. Power consumption is under 12μA with 10μA of that going through the thermistor as sensing current. Lower current (<2μA) versions are planned. Inside is a current source to feed the PTC and a reference voltage with ...

Texas Instruments has releases an RS-485 transceiver that can be pin-programmed to suit networks with different bus voltage, logic voltage, network length and throughput. Called THVD1424, it includes switchable on-chip 120Ω termination resistor, slew rate control, and both half-duplex (two-wire) and duplex (four-wire) modes – allowing a single PCB type to be created that can be software re-configured for different ...
