Oct 16 14
Texas Instruments (TI) introduced the fully integrated high-brightness LED matrix manager IC for adaptive automotive headlight systems. The TPS92661-Q1 is a compact, scalable solution that enables automobile manufacturers to create innovative LED headlamps that vary beam patterns and intensity dynamically for optimum roadway illumination and enhanced driver safety. Featured in premium vehicles and proliferating into mainstream models in the coming years, adaptive headlamp systems automatically manage the direction and intensity of high and low beams. The TPS92661-Q1 is a compact solution for shunt FET dimming arrays of high-brightness LEDs and includes 12 individually controlled MOSFET switches to steer current through or around the connected LEDs, thereby providing individual pixel-level light adjustment. A serial communication port facilitates control and diagnostic functions from a master microcontroller, such as TI's AEC-Q100-qualified C2000 Piccolo. Features and benefits of TPS92661-Q1: Controls up to 96 LEDs from a single serial port for headlamp beam forming and directional control. Individual 10-bit pulse-width modulation (PWM) brightness control LED for pixel-level light intensity adjustment. LED open/short fault diagnostics and reporting alerts driver via the master microcontroller in the event of headlamp failures or damage.
Texas Instruments Incorporated Introduces DRV10983 BLDC Motor Driver
Oct 16 14
Texas Instruments Incorporated, has introduced DRV10983, the 24-V, sinusoidal, sensorless, brushless DC, or BLDC, motor driver. The DRV10983 gives customers the ability to quickly tune their motors for reliable start-up and optimal performance using a configurable, 3-A driver with integrated control logic. Utilizing 180-degree, sinusoidal, sensorless technology, the DRV10983 is up to 75% quieter than competing solutions for applications like cooling fans, ceiling fans, blowers and small appliances. Pure tone harmonics, a significant noise adder in fan applications, are reduced by as much as 25 dBA. Key features and benefits of the DRV10983 include: Tuning a wide range of motors for optimal performance and reliable start-up through simple register settings without the need for complex microcontroller coding or motor knowledge; advanced on-chip protection, including anti-voltage surge (AVS) over-voltage, over-current, over-temperature, shoot-through, under-voltage lock-out and advanced five-stage rotor lock protection, reduces design complexity and increases system reliability; and single-chip solution with integrated power FETs, sensorless control logic and optional 100-mA, 3.3- or 5-V step-down converter reduce board space, system cost and development time.

Texas Instruments Expands New High-Voltage SAR ADCs Deliver Total System Accuracy for Multi-Channel Industrial Applications
Oct 8 14
Texas Instruments expanded its successive approximation register (SAR) analog-to-digital converter (ADC) portfolio with the first devices in a new high-voltage family. The eight-channel ADS8688 and four-channel ADS8684 allow input ranges up to +/- 10.24 V to be powered by a single 5-V supply, greatly simplifying system power requirements. They feature the industry's lowest gain drift, offset voltage and offset drift, and the high precision reference, giving engineers unprecedented levels of accuracy for their designs throughout the full extended industrial temperature range. Key benefits of the ADS8688 family: No high-voltage supplies needed: Simplifies system design by eliminating the need to generate separate high-voltage supplies. The devices support bipolar input ranges up to +/- 10.24 V and unipolar ranges up to +/- 10.24 V with a single 5-V supply. DC error performance: Achieve better than 99.9% accuracy without calibration with DC error specifications that boost system-level performance. With specified gain drift of 4 ppm/C and offset drift of 3 ppm/C, the devices eliminate the need for designers to spend time calibrating their systems over temperature ranges. Performance across temperature ranges: An integrated precision reference and reference buffer improve low-temperature drift specifications, enabling precision performance without requiring external circuitry across the full extended industrial temperature range of minus 40 C to 125 C. High integration for industrial sensor designs: Each device integrates into one chip 20 active devices, including programmable gain amplifiers (PGAs), driver amplifiers, multiplexer, voltage reference, reference buffer and SAR ADC, plus an auxiliary channel input for interfacing straight to the ADC. This integration allows the ADS8688 and ADS8684 to connect directly to various sensor types that require no signal conditioning. TI offers a range of support tools to speed time to market for designers using the ADS8688 family, including simulation models, hardware evaluation kits and reference designs. System designers can evaluate the ADS8688 and ADS8684 in a fraction of the time they might spend evaluating other precision ADCs by using a new performance demonstration kit (PDK) that features a simple installation process. The PDK includes an evaluation module (EVM) and simple capture card for plug-and-play functionality, replacing online software installations with a simple one-click process. The kit's intuitive, easy-to-use graphical user interface (GUI) enables designers to quickly evaluate ADC performance in specific end equipment.
