STMicroelectronics POWERSTEP01TR, Stepper Motor Motor Driver IC 89-Pin, VFQFPN

The STMicroelectronics integrating micro stepping controller, 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.

Sensorless stall detection
Integrated voltage regulators
SPI interface
Low quiescent standby currents
