To build the next generation of robotic actuators, engineers need components that guarantee two things: precise position feedback and fluid motion. Allegro MicroSystems enables this leap by combining our high-resolution XtremeSenseTM TMR and inductive sensors with smooth, low latency 48V gate drivers. Together, these highly integrated solutions empower you to design compact, efficient joints that deliver lifelike, responsive actuation and pinpoint accuracy.
Humanoids, Cobots and AMR built on Allegro's best-in-class accuracy magnetic current sensors, cutting-edge inductive motor position sensors, and highly integrated 48V gate drivers. These applications benefit from precise torque control, robust joint positioning, and compact efficient actuator designs that extend battery life and improve safety in human-robot interactions.
Build the next generation of industrial robots, linear transport systems, and forklifts with Allegro’s robust semiconductor portfolio. Our compact motor position sensors and power-dense current sensors deliver reliable positioning and precise motion control in space-constrained joints. For efficient, high-voltage power conversion, highly integrated Power-Thru™ isolated gate drivers maximize SiC and GaN performance, ensuring ultimate reliability and uptime in demanding environments.
Empower your consumer robot designs with Allegro's micropower Hall switches and latches, featuring wider airgap tolerances that reduce overall system costs. For compact, high-performance motion control, our integrated FET motor drivers utilize QuietMotion™ integrated FOC algorithms to drastically reduce audible noise.
