â€˜digital SPIN', or dSPIN, combines the digital
control, analog measurement and power electronic circuitry for controlling
stepper motors using ST's BCD fabrication process. It is the first device in
ST's new dSPIN family of monolithic
motor-control ICs. Implementing the motor-control calculations in hardware
simplifies software design by requiring only acceleration, deceleration, speed
and target position commands from the application microcontroller. This frees
microcontroller resources to support other differentiating features.
voltage-mode approach allows full digital control, feeding the motor phases
with an accurate sinusoidal waveform and resulting in position resolution of
128 microsteps per step. Other advantages include reduced resonances,
mechanical noise and low-speed vibration, as well as reduced speed and torque
ripple at low speeds.
has taken advantage of analog integration using its advanced BCD process to
implement rich protection features on the chip. These include over-temperature
protection, low bus voltage protection, non-dissipative over-current protection
and motor stall detection.

A simple new chemical method for repairing and recycling notoriously difficult carbon fiber composites has been developed by the Fraunhofer Institute for Applied Polymer Research. An entire component can be completely recycled, including reclaiming its expensive carbon fibers for reuse.
In today’s connected world we are seeing the beginning of connected homes, smart grids, self-driving automobiles, drones, and many other amazing devices. Out of all the soon-to-be connected devices, which device poses the greatest dangerous to its users and society?
