Performance Motion Devices now sells new Juno Step Motor Control Integrated Circuits (ICs) in a 56-pin VQFN package. The new Juno Step Motor Control IC is the latest addition to the Juno Velocity and Torque Control IC family … the industry’s first family of compact ICs with full four-quadrant motion control; direct input accepted from quadrature encoders; profile generation; and advanced current control.

Juno ICs are for designs with limited space that need to control noise, vibration, and power consumption. Juno ICs are also easy to deploy with embedded motion commands and onboard intelligence.

The Juno Step Motor Control IC 56-pin VQFN package has the highest PWM frequencies offered by Performance Motion Devices and the smallest IC parts — measuring 7.2 x 7.2 mm. Juno Step Motor Control ICs are available both with encoder input and without.

The Juno Step Motor Control IC also comes with numerous safety features … including stall detection, over- and under-voltage sense, overcurrent detection, over-temperature, and i²t current foldback. Coupled with compact MOSFETs, the Juno Step Motor Control IC can replace older step motor amplifiers and dramatically reduce the size and heat output.

“Juno Step Motor Control ICs offer embedded motion and use a proprietary current control technique that results in ultra-smooth, quiet, and efficient motion of the step motor,” said Chuck Lewin, CEO of Performance Motion Devices.

“By driving step motors more quietly and rapidly, existing step motor-based systems can get a performance boost and avoid an expensive transition to a brushless dc motor. In short, this IC lets step-motor users upgrade the controls but keep the motor … and get a big jump in machine performance.”

The Juno IC family is suitable for a wide range of applications including precision liquid pumping, packaging and lab automation, pick and place machines, flow rate control, XYZ tables, and many other robotic, scientific, and industrial applications.
