TMC5041-LA

简介

The TMC5041 cDriver™ is an integrated motor driver and motion controller solution for CCTV cameras, pumps and other automated equipment applications. The device has two integrated SixPoint™ ramp controllers, microstepping indexers, the sensorless stall detection technology StallGuard2™ and the completely noiseless current control mode StealthChop™ and is intended to drive two bipolar stepper motor. The output driver blocks consists of low RDSon N-Channel power MOSFETs configured as full H-bridges to drive the motor windings. The TMC5041 is capable of driving up to 1.5A of current from each output (with proper heatsinking). TMC5041 is designed for a supply voltage of 5...28V. The device provides a SPI interface for configuration and diagnostics and a step and direction interface.Special Featuresmicrostep tableCoolStep™passive brakingshort detectionSpreadCycle™Stall detectionStallGuard2™StealthChop™
