POWERSTEP01TR

POWERSTEP01TR is a system-in-package integrating microstepping controller and 10A power MOSFETs. The powerSTEP01 is a system-in-package integrating 8 N-channel 16mohm MOSFETs for stepper applications up to 85V with an SPI programmable controller, providing a full digital control of the motion through a speed profile generation and positioning calculations. It integrates a dual low RDS(on) full-bridge with embedded non-dissipative overcurrent protection. The device can operate with both voltage mode driving and advanced current control fitting different application needs. The digital control core can generate user’s defined motion profiles with acceleration, deceleration, speed or a target position easily programmed through a dedicated register set. typical applications are high power bipolar stepper motor, stage lighting, surveillance systems, textile and sewing machines, pick and place machines.
