Analogue / Linear / Mixed Signal ICs

Power Integrations has added to its isolated gate driver family, for mosfets and IGBTs, with a 5A driver in a wide-body eSOP package. 5A is enough for switches handling 300A, or more if an external booster circuit (see diagram) is added to push the drive to 60A. “This device provides n-channel drive for both the low and high side booster mosfet ...

Maxim is aiming at medical wearables with a set of chips for sensing various vital signs. In particular, its chips are aimed at wearables that meets US Fedral Drug Administration (FDA) sensing specifications – so far, said Maxim, no wearables have achieved FDA approval. MAX86141 is an autonomous dual-channel (for two photodiodes) optical pulse oximeter plus heart rate sensor, measuring ...

  AMS has announced a configurable capacitive sensing front end which allows speed and resolution to be traded to optimise designs. Called PCap04, it can capture and digitise 50,000 times per second at its fastest setting, or achieve 8aF resolution at its most sensitive. “Configurability also enables sensor manufacturers to trade measurement speed off against power consumption. In low-power mode, ...

AMS has launched a NFC tag IC with industrial-grade quality, intended for high-reliability long term use. Called AS3956, it is intended to act as a contactless bridge between a microcontroller and NFC readers or NFC-equipped phones. The chip is able to operate fully powered by the RF field, without any external supply, and can supply 5mA to external loads. “This, combined ...

TI has launched an inductor-inductor-capacitor (LLC) resonant controller with an integrated high-voltage gate driver that enables, claims TI, the industry’s lowest standby power, as well as longer system lifetimes. The UCC256301 provides a cost-effective system solution that helps meet stringent energy-efficiency standards for a wide range of AC/DC applications, including digital televisions, gaming adapters, desktop computer and notebook adapters, and ...

Rohm has anounced a high definition audio system reference design, aimed at Hi-fi audio equipment, Bluetooth speakers, separate audio components and USB audio DACs.

Silicon Labs has announced a family of car radio receiver chips with a common software API, claiming designers can share R&D effort across multiple product lines, from low-cost, single-tuner AM/FM radios to high-performance systems with multiple tuners and antennas. Si4795x (branded Global Eagle, (right)),  Si4796x and Si4797x (together branded Dual Eagle) are analogue AM/FM receivers and digital radio tuners, all with ...

Designed to support the supervisory circuits of microprocessors, the APX803L micro-power voltage detector from Diodes offers a detection between 1.2 and 5.0V in 0.1V steps, while consuming 1μA (typ, 2.5μA max). Threshold accuracy is ±1.5%, and no external components are required. Whenever the monitored power supply rail drops below the chosen threshold, the APX803L asserts a reset signal within 20μs ...

LTC2063 from Analog Devices draws just 1.3μA (typ, 2μA max) from a 1.8V supply and achieves 5μV maximum input offset at 25°C

Microchip has introduced a range of CAN transceivers which includes an automotive Grade 0 qualified device. Designated the ATA65XX family, the devices support the recently established CAN FD (Flexible Data-rate) protocol for up to 5Mbit/s communication speed and the new CAN PN (Partial Networking) standard for improved energy efficiency for vehicles. The devices are compliant with the ISO 118980-2/5/6, 11898-2:2016 ...
