Performance Motion Devices MC73110

QUICK TAKE:
Generating PWM waveforms at frequencies up to 40 kHz, the MC73110 motor controller promises to lower torque ripple while maintaining smooth operation. The single-axis device provides digital velocity and torque control for brushless dc motors and requires just a MOSFET or IGBT triple half bridge to create a complete intelligent motor controller.

MORE INFO:
The MC73110 operates in one of three modes: internal velocity profile mode, velocity mode with an external command signal, and torque mode with an external command signal. It provides software-programmable velocity and current loops, six-step and sinusoidal commutation, analog or digital command input, profile generation, and digital current loop. It can be operated as a stand-alone intelligent motion IC, or via serial commands as a programmable axis controller. The IC comes in a 64-pin PQFP and operates from a 3.3V supply. (See figure)

APPLICATIONS
The MC73110 is well-suited for low-cost brushless motor amplifiers. It can be used in applications such as medical automation, centrifuges, tape drives, machine tools, scientific instrumentation, semiconductor equipment, HVAC, pumps and compressors, and general automation. The higher-speed PWM output is ideal for low inductance motors and with applications that require high motor velocity or high acceleration.

PRICING & AVAILABILITY
Available now, the MC73110 starts at $18 each in OEM quantities.
