The TMC2240 is a smart high-performance stepper motor driver IC with serial communication interfaces (SPI, UART) and extensive diagnosis capabilities. It combines industries’ most advanced stepper motor driver based on the 256-usteps built-in indexer and two fully integrated 36V, 3.0A (max) H-Bridges plus non-dissipative Integrated Current Sensing (ICS).TMC2240 features abundant diagnostics and protections such as short protection / OCP, thermal shutdown, under voltage lockout. During thermal shutdown and under voltage lockout events the driver is disabled. Furthermore, TMC2240 provides functions to measure the driver temperature, estimate the motor temperature, and measure one external analog input.ApplicationsTextile, Sewing Machines, Knitting MachinesLab and Factory Automation3D Printers, ID Printers/Card PrintersLiquid Handling, Medical ApplicationsOffice Automation and Paper HandlingPOS, Massage ChairsATM, Cash Recycler, Bill Validators, Cash MachinesCCTV, SecurityPumps and Valve ControlHeliostat and Antenna Positioning

The TMC239 is a smart high current microstepping driver for bipolar stepper motors. It provides an SPI interface as well as the classical analog / digital control. A full set of protection and diagnostic features makes this device very rugged. It directly drives external MOSFETs for currents up to 6A. This way it reaches an extremely high efficiency and allows driving of a high motor current without cooling measures even at high environment temperatures. With the new chip-scale QFN package a 4A motor driver can be realized on the size of a stamp!The high motor current makes this device ideal for miniaturized highly dynamic and high torque drive systems.APPLICATIONSTextile, Sewing MachinesOffice AutomationPrinter and ScannerATMCash recyclerPOSAntenna PositioningPumps and ValvesLab AutomationLiquid HandlingMedical

The TMC246 provides an integrated motor driver solution for Laboratory Automation, Scanners and other automated equipment applications. The device has an integrated microstepping current control and the sensorless stall detection technology StallGuard™ and is intended to drive a bipolar stepper motor. The output driver block consists of low RDSon TrenchFET power MOSFETs configured as full H-bridges to drive the motor windings. The TMC246 is capable of driving up to 1.5A of current from each output (with proper heatsinking). TMC246 is designed for a supply voltage of 7 to 34V. The device has a SPI interface for control and diagnostics.APPLICATIONSReplace Classic Bipolar Driver ICsOffice AutomationPrinter and ScannerHeliostat ControllerATM, Cash recyclerPOSCCTV, SecurityAntenna PositioningPumps and ValvesLab AutomationLiquid HandlingMedica
