Texas Instruments (TI) has introduced isolated modulators for use in precision motor control and system protection in robotics.
The trio of devices enable increased precision and higher resolution of 12 to 14 effective number of bits (ENOB) for accurate and reliable phase current sensing and DC voltage sensing measurements, TI said. The goal is to achieve smooth torque operation and fine motor control while decreasing size and cost in robotics.
TI said the precision of the AMC0106M05, AMC0136 and AMC0106M25 isolated modulators make it possible for robots to complete a variety of tasks like:
- Threading a needle
- Handling small nuts or bolts
The ICs also require 50% less space than other reinforced isolation solutions, TI said. This reduction in size means designers can add features for more precision control and reliable operation in compact robotic applications.
“These modulators from TI enable designers to increase robotics accuracy and productivity in new use cases and smaller form factors, from the factory floor to the operating room,” said Karthik Vasanth, vice president and general manager of Data Converters and Clocks at TI. "For example, where humanoid robots could previously only complete simple tasks, our new functionally isolated modulators now allow them to carry out more dexterous and precise jobs.”
