Performance Motion Devices Juno® Velocity & Torque Control ICs

Performance Motion Devices Juno® Velocity and Torque Control ICs provide advanced control for brushless DC, DC brush motors, and step motors. These compact ICs integrate full four-quadrant motion control, direct input quadrature encoder, profile generation, and advanced current control. Juno ICs are targeted for medical, scientific, industrial, and robotic applications that need to minimize motor noise, vibration, and power consumption. Juno ICs are easy to deploy with embedded motion commands, on-board intelligence, and direct analog and digital amplifier signal interfacing.

Juno ICs interface to external bridge-type switching amplifiers and utilize Performance Motion Device’s proprietary current and switch-signal technology for ultra-smooth operation. Depending on the type of motor controlled, Juno ICs provide motor commutation, microstep generation, pulse and direction input, internal profile generation, and much more.

Juno ICs are equipped with advanced amplifier management features such as overcurrent, over/undervoltage, and overtemperature sense. A special outer control loop allows a wide range of motor-related control applications, including pressure, flow rate, and temperature control.

Juno ICs are offered in three major product groups:

Juno Velocity Control ICs: Sophisticated velocity and torque control of 3-phase DC brush and brushless DC motors
Torque Control ICs: Ultra precise torque control for 3-phase brushless DC and DC brush motors with direct analog or SPI command input
Step Motor Control ICs: State of the art step motor control with pulse and direction or SPI command input

These devices are offered in compact 64-pin TQFP and ultra-compact 56-pin VQFN packages.
