DESCRIPTION

· The Juno Family of ICs offers advanced velocity and torque control for Brushless DC, DC Brush, and step motors.
· They are the first compact ICs with full four quadrant motion control, direct input quadrature encoder, profile generation, and advanced current control.
· Designed for medical, scientific, industrial, and robotic applications, they minimize motor noise, vibration, and power consumption.
· Easy to deploy with embedded motion commands, on-board intelligence, and direct analog and digital amplifier signal interfacing.
· Interface with external bridge-type switching amplifiers using proprietary current and switch-signal technology for smooth operation.
· Provide motor commutation, microstep generation, pulse and direction input, and internal profile generation based on motor type.
· Equipped with integrated safety features like overcurrent, over/undervoltage, and overtemperature sense.
· Offered in three major product groups: Velocity Control ICs, Step Motor Control ICs, and Torque Control ICs.
