Toshiba Electronics Europe GmbH has launched 100V N-channel power mosfets for automotive applications, available in the surface mount SOP advance (WF) package. Designed for 48V system applications, the devices are suitable use in boost converters for integrated starter generators and LED headlights as well as motor drives, switching regulators and load switches. The XPH6R30ANB device boasts on-resistance RDS (ON) value ...

Analog Devices has introduced the LTM4668 and LTM4668A µModule regulators, quad-output dc-dc regulators with up to 4.8A output capability. The devices integrate switching controllers, power FETs, inductors and support components, reducing power consumption and board space, ADI says. They are designed for telecom, networking and industrial applications. Operating over an input voltage range of 2.7V to 17V, the LTM4668 and ...

Microchip is offering high security IoT authentication to companies with no prior security knowledge, that are producing as few as 10 units. Authentication, in this case, is proving the identity of a device attempting to connect across a network using asymmetric cryptography. Called ‘Trust Platform’, this is a ‘pre-provisioned’ hardware-based secure key storage system, which also offers solutions for mid and ...

Thingy:91 is a cellular and GNSS IoT prototyping platform with world-wide coverage across 700MHz to 2200MHz, created by Nordic Semiconductor and Fractus Antennas. Based on Nordic’s nRF9160 SiP multimode LTE-M/NB-IoT system-in-package with GPS, the battery-powered Thingy:91 comes with a roaming SIM card, 16 sensors and a nRF52840 for short-range wireless communication with Bluetooth 5, Thread, Zigbee and ANT. The SIM is a Nano ...

Maxim is claiming industry’s smallest package, and longest battery life, for its latest real-time clock (RTC) chip – at 2 x 1.5mm and <180nA. The chip is called MAX31341B. “Systems that use microcontrollers for accurate timekeeping waste battery life, which is unacceptable in wearable applications. MAX31341B is designed with power-management circuitry that remains on during dormant periods, providing timekeeping so ...

The IQOV-220 OCXO features high stability and low phase noise. It delivers frequency stability performance down to ±0.5ppb (parts per billion) over the full industrial temperature range of -40 to 85°C with a short term stability (Allan deviation) of 0.5ppt (tau=1s). With a holdover spec of 6µS over 24 hours, a close in phase noise of typically -140dBC/Hz at 10Hz ...

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 ...

Maxim’s DS2477 secure co-processor is intended to protect industrial, medical and IoT applications with authentication and physical security. “It is a secure I2C co-processor with built-in 1-Wire master that combines FIPS202-compliant secure hash algorithm [SHA-3] challenge and response authentication with Maxim’s ChipDNA feature to provide protection against security attacks,” said Mouser, which is stocking the part. ChipDNA is Maxin’s brand for ...

Maxim is claiming simple route to protecting sensitive data in IoT end-nodes with a pair of security supervisor chips. Called MAX36010 and MAX36011, “these make it easier for designers to implement robust tamper detection, cryptography and secure storage while safeguarding sensitive information via logical and physical protections, without having to be security experts themselves – that can be integrated into a ...

Toshiba has announced an automotive chip that can bridge between PCIe and two Ethernet standards: Ethernet AVB and Ethernet TSN, to connect central processors to telematics, infotainment and driver assistance systems, as well as sensors, at up to 1Gbit/s. Called TC9562XBG, “it’s not just a simple hardware-bridge between PCIe and Ethernet”, Toshiba Electronics Europe told Electronics Weekly. “Through the built-in ...
