LED drivers bring high-end lighting technology to mainstream vehicles
A I
llegro MicroSystems, a global leader in sensing and power solutions for motion control and energy-efficient systems, has expanded its automotive lighting portfolio to include two new offerings for advanced driver assistance system (ADAS) applications. The A80803 leverages multi-topology conversion and patented IP to enable smooth high/low/high beam transitions in a single integrated circuit (IC). The A80804 linear LED driver provides high power for automotive lighting applications through multiple, independently-configurable channels. Both products help designers reduce the number of ICs required to create safety-enhanced automotive lighting systems, enabling
higher performance and more compact designs at lower system cost. The A80803 is a switch-mode, constant- current controller for high-power LED automotive lighting applications that addresses many common pain points for headlight designers, with features that make it easier for headlight designers to bring advanced functionality to mainstream vehicles. The multi-topology single-ended controller design, combined with wide input/output voltage capability, provides a universal solution for a wide variety of use cases and/or number of LEDs. Options for SPI-based control or EEPROM-based end-of-line programming for standalone operation further extend the range of possibilities.
The A80804 is Allegro’s fi rst four-channel linear driver for high-power LEDs. In addition to targeted applications such as DRL/ position and stop/tail lights, it gives lighting designers increased design fl exibility for popular features such as sequential turn signals, animation effects, and theater-
style transitions. No switching elements or inductors are required, and the A80804’s low EMI output helps it achieve CISPR25 Class 5 compliance. It also offers multiple analogue and PWM dimming methods, dual brightness mode operation, and is confi gurable without the need for a microcontroller.
ITTIA launches edge data processing and management database for microcontrollers, MCUs
TTIA, a provider of high-performance embedded database software for autonomous systems and Internet of Things (IoT) devices, has released the ITTIA database for microcontroller (MCU) devices, ITTIA DB IoT.

ITTIA DB IoT for MCUs is a time series embedded database for data processing and data management on devices running real time operating systems (RTOS). This database technology is suitable for device applications
that require fast response to process data, such as events and alarms, that both push and pull updates. It is architected for sensors to process streams of data and enables devices to separate valuable information from massive raw data by monitoring, collecting, processing, and running embedded continuous queries. This embedded database balances edge and cloud computing for scalable IoT Systems. ITTIA DB IoT will enable manufacturers of embedded systems and internet of things (IoT)
devices to optimize data management costs, reduce latency, increase scalability, and benefi t from the ease of development for deploying and managing complex embedded systems. The ability of ITTIA database for MCUs empowers devices to process time series data streams in real time, while devices locally manage collected data for future analysis and querying. Systems embedded with ITTIA DB IoT effi ciently ingest time series data from various data sources
onto local fl ash media, export analyzed data in timestamp order, and run real time queries according to application data management requirements.
ITTIA DB IoT is available for evaluation at:
