Flexible 12-channel Automotive LED Driver from STMicroelectronics Simplifies State-of-the-Art Lighting

Geneva, October 7, 2019 –The STMicroelectronics ALED1262ZT 12-channel LED driver targets advanced automotive rear combination lamps and interior lighting, bringing features to support complex and innovative visual effects.
 
Independent 7-bit PWM dimming on all channels allows flexible control of tail, stop, and indicator lights, with dynamic effects. Each channel delivers constant output current at 19V for controlling multi-LED series strings. Adjustment from 6mA to 60mA ensures a wide dimming range with high maximum brightness. The LED lighting driver responds to I2C commands from a host microcontroller and provides two pre-programmed configurations that allow standalone operation for extra flexibility.
 
With diagnostic features including open-LED detection and over-temperature warning with thermal shutdown, the ALED1262ZT ensures long-lasting robustness and stability. The input-voltage range from 5.5V to 38V allows use in direct battery-connected systems. In addition, the ALED1262ZT is designed for low-noise operation, with slow turn-on/off time per channel and spread-spectrum clock operation to simplify integration with other in-vehicle electronics.
 
The ALED1262ZT is in production now, in a 6.4mm x 7.8mm thermally efficient HTSSOP24 exposed-pad package, from $1.00 for orders of 1000 pieces.
 
ST has also released an evaluation board, STEVAL-LLL002V1, available from www.st.com or distributors, to help designers explore the ALED1262ZT’s features and jump-start new lighting designs.

Why Does It Take a Pandemic to Realize the Value of Remote Patient Monitoring?

Sponsored by Maxim Integrated

The headlines that COVID-19 are bringing to us each day serve to highlight the promise of remote patient monitoring. According to the U.S. Centers for Disease Control and Prevention, 6 in 10 American adults live with at least one chronic disease and 4 in 10 adults have two or more. The time is now to embrace and accelerate the deployment of remote patient monitoring to ensure that chronic conditions are managed in a way that can improve outcomes and reduce the need for regular healthcare facility visits.

Cloud Computing for Electronic Design (Are We There Yet?)

Sponsored by Cadence Design Systems

When your project is at crunch time, a shortage of server capacity can bring your schedule to a crawl. But, the rest of the year, having a bunch of extra servers sitting around idle can be extremely expensive. Cloud-based EDA lets you have exactly the compute resources you need, when you need them. In this episode of Chalk Talk, Amelia Dalton chats with Craig Johnson of Cadence Design Systems about Cadence’s cloud-based EDA solutions.
