The TMC5130A is a high performance stepper motor controller and driver IC with serial communication interfaces. It combines a flexible ramp generator for automatic target positioning with industries' most advanced stepper motor driver. Based on TRINAMICs sophisticated stealthChop chopper, the driver ensures absolutely noiseless operation combined with maximum efficiency and best motor torque. High integration, high energy efficiency and a small form factor enable miniaturized and scalable systems for cost effective solutions. The complete solution reduces learning curve to a minimum while giving best performance in class. 2-phase stepper motors Drive Capability up to 2A coil current (2.5A peak) Motion Controller with sixPointTM ramp Step/Dir Interface with microstep interpolation microPlyerTM Voltage Range 4.75. 46V DC SPI & Single Wire UART Encoder Interface and 2x Ref.-Switch Input Highest Resolution 256 microsteps per full step stealthChopTM for extremely quiet operation and smooth motion spreadCycleTM highly dynamic motor control chopper dcStepTM load dependent speed control stallGuard2TM high precision sensorless motor load detection coolStepTM current control for energy savings up to 75% Integrated Current Sense Option Passive Breaking and freewheeling mode Full Protection & Diagnostics Compact Size 9x9mm2 TQFP48 package BLOCK DIAGRAM
