Maxim EV Battery Management System
Maxim has launched MAX17843, a 12-channel, high-voltage smart sensor data-acquisition device that allows automotive OEMs to enhance the safety of their lithium-ion battery packs with communications, diagnostics and lower system costs.
MAX17843 meets high safety standards, adhering to ISO 26262 and ASIL D requirements (also applicable for ASIL C). Its differential universal asynchronous receiver/transmitter (UART) using capacitive isolation reduces bill of materials (BOM) costs and failure in time (FIT) rates. With this, designers can save up to 90% of their isolation BOM cost.
Microsemi Avalanche Board
Microsemi and Future Electronics have announced the availability of the Avalanche board, featuring a Microsemi PolarFire non-volatile field programmable gate array (FPGA). The Avalanche development board includes a RISC-V-based soft CPU pre-programmed to the kit, offering a RISC-V-based board for low cost market applications utilizing RISC-V open instruction set architectures (ISAs) at mid-range densities.
This supports the ongoing expansion of Microsemi’s Mi-V ecosystem, which brings together industry leaders involved in the development of RISC-V to leverage their capabilities and streamline RISC-V designs for users. The Avalanche development board also features serial flash memory, double data rate type three (DDR3) DRAM and a VSC8531 triple speed PHY powered by Microsemi’s LX7167 2.4A hysteretic step-down regulator.
Pasternack Phase Locked Oscillators
Pasternack has unveiled a line of phase locked oscillators (PLOs) that deliver accurate and stable output frequencies with low phase noise, making them ideal for use in radar and other exciter or frequency generation systems. Typical applications include phase locked loops, frequency synthesizers, function generators, and as a local oscillator source in receiver and transmitter stages.
The 20 phase locked oscillator models are offered with fixed output frequencies of 50, 100, 500, 1000, 2000, 4000 and 6000MHz. Typical performance for these PLOs includes a phase noise of -105dBc/Hz at 10kHz offset, a buffered output power level of 7dBm, second harmonic suppression levels of -25dBc, and spurious suppression levels of -70dBc. They require an external frequency reference of either 10MHz or 100MHz and feature a transistor-transistor logic (TTL) lock detect output to signal an out-of-lock condition.
Samsung Application Processors
Samsung has announced its Exynos 9 Series 9810 application processor. The Exynos 9810, built on the company’s second-generation 10nm FinFET process, increases performance in smartphones and smart devices with its third-generation custom CPU, faster gigabit LTE modem and image processing with deep learning-based software.
The Exynos 9810 has an eight-core CPU under its hood, four of which are custom cores that can reach 2.9GHz, with the other four optimized for efficiency.
TI Headlight DLP Technology
Texas Instruments (TI) has unveiled DLP technology for high-resolution headlight systems. The DLP chipset combines programmability and high resolution (more than one million addressable pixels per headlight), exceeding the resolution of existing adaptive driving beam (ADB) technologies by more than 10,000 times.
Automakers and Tier-1 suppliers can use this programmable ADB solution to design headlight systems that maximize brightness for drivers on the road while minimizing the glare to oncoming traffic or reflections from retroreflective traffic signs. This DLP technology works with any light source, including LED and laser illumination, and gives engineers a way to more precisely control light distribution on the road with customizable beam patterns.
