Switches TRINAMIC Motion Control GmbH & Co. KG Hamburg, Germany TMC5041 DATASHEET (Rev. 1.10 / 2015-MAR-25) 2 APPLICATION EXAMPLES: HIGH FLEXIBILITY MULTIPURPOSE USE The TMC5041 scores with power density, complete motion controlling features and integrated power stages. It offers a versatility that covers a wide spectrum of applications from battery systems up to embedded applications with 1.5A motor current per coil. The small form factor keeps costs down and allows for miniaturized layouts. Extensive support at the chip, board, and software levels enables rapid design cycles and fast time-to-market with competitive products. High energy efficiency and reliability deliver cost savings in related systems such as power supplies and cooling. MINIATURIZED DESIGN FOR UP TO TWO STEPPER MOTORS Two reference switch inputs Ref. Switches can be used for each motor. A single CPU controls the SPI High-Level whole system, which is M CPU TMC5041 Interface highly economical and space saving, because the TMC5041 covers all functionality required to drive the motor.
