New InstaSPIN™-BLDC Solution
Targeted at low cost BLDC applications, TI’s new InstaSPIN-BLDC is a sensorless control technique based on the premise that “simple is better.” In field tests with over 50 different motor types, InstaSPIN-BLDC was able to get each motor up and running in less than 20 seconds!

New Hercules™ safety microcontroller platform
The new Hercules ARM® Safety MCU platform for medical, industrial and transportation safety-critical applications includes three tailored families to choose from so you can optimize and differentiate your design. The RM4x series designed for high-performance safety-critical applications, TMS570 series designed for transportation safety-critical applications, and the TMS470M series designed for safety applications requiring less performance.

Sitara ARM MPU makes its way into industrial drives
Increasingly, industrial drives are being designed with industrial communication interfaces. Considering the large number of communication standards, these interfaces are modular and are therefore able to provide support for a broad range of communication technologies to a traditional industrial drive. One of these is PROFIBUS and is deployed in millions of industrial devices every year, including in drives. The AM1810 Sitara ARM MPU integrates the PROFIBUS interface on the chip itself by using the real-time subsystem called the PRU subsystem (For details, see the PRU White Paper). When coupled with a real-time kernel, the AM1810 with TI’s portfolio of PWM drivers and motor feedback solutions offers a competitive solution for motion control. Learn more about AM1810 and PROFIBUS. Also, earlier this year, TI had announced membership in EtherCAT Technology Group. So, stay tuned for more announcements regarding EtherCAT in 4Q 2011.
Video: Overview of the Hercules™ Platform of Safety MCUs

The Hercules platform of Safety Microcontrollers consists of three ARM Cortex-based microcontroller families that deliver scalable performance, connectivity, memory and safety features for applications that require a high level of reliability. This video gives an overview of the Hercules RM4, TMS570 and TMS470M MCU families and the development tools that are available.

First autofocus driver in ultra-thin packaging for compact camera modules
DRV201 Driver The new DRV201 is the industry’s first auto focus voice coil motor driver that supports both pulse width modulation (PWM) and linear current regulation. PWM current regulation extends battery life and is up to 75% more efficient than linear current regulation. The DRV201’s advanced ringing compensation algorithms enable ultra fast auto focus times in compact cameras, smart phones, and digital still cameras. The DRV201 is housed in TI’s PicoStar™ packaging, which is the industry’s thinnest package at 0.15mm, enabling low-profile camera modules. The device has a robust ESD rating of 4kV.
*New* Integrated Motor Drivers and EVMs
New additions to the DRV8x portfolio provide integrated solutions for even more motor drive applications. Whether you are looking for a scalable 3-phase pre-driver or a brushed DC driver that will give consistent performance over the lifetime of a battery, the products you have asked for are here. New evaluation modules and kits make it easy to check out the device that’s right for your application.

Design News Visits TI Motor Lab
In late June, Texas Instruments gave editors and writers a tour of TI’s Motor Lab. During an introduction, Tim Adcock, director of the Motor Lab, explained that automotive companies, appliance manufacturers, and even toy suppliers have switched from brushed DC motors to brushless DC motors.
EE Times presents, A simple algorithm for microstepping a bipolar stepper motor
By Jose Quinones, Texas Instruments Motor Solutions Team
Here’s a simple algorithm that uses conventional microcontroller blocks to control commercially available H-bridges to properly commutate a bipolar stepper motor through a microstepping profile.
