Trinamic (TMC2209-LA-T) Motor Driver/Controller, 4.75V to 29V

Motor Driver/Controller, Stepper, 4.75V to 29V, 2A/1 Output, QFN-28Product OverviewTMC2209-LA-T is an ultra-silent motor driver IC for two phase stepper motors.TMC2209 pinning is similar to a number of legacy drivers as well as to theTMC2208. TRINAMICs sophisticated StealthChop2 chopper ensures noiselessoperation, maximum efficiency, and best motor torque. Its fast currentregulation and optional combination with SpreadCycle allow highly dynamic motionwhile adding. StallGuard for sensorless homing. The integrated power MOSFETshandle motor currents up to 2A RMS with protection and diagnostic features forrobust and reliable operation. A simple to use UART interface opens up tuningand control options. Store application tuning to OTP memory. Industries' mostadvanced STEP/DIR stepper motor driver family upgrades designs to noiseless andmost precise operation for cost-effective and highly competitive solutions. Itis used in 3D printers, printers, POS, office and home automation, textile,sewing machines, CCTV, security, ATM, cash recycler and HVAC.2-phase stepper motors up to 2.8A coil current (peak), 2A RMSSTEP/DIR Interface with 8, 16, 32 or 64 microstep pin settingSmooth running 256 microsteps by MicroPlyer interpolationStealthChop2 silent motor operationCoolStep current control for energy savings up to 75%Low RDSon, low heat-up LS 170mohm and HS 170mohm (typ at 25°C)Voltage range from 4.75VDC to 29VDCLow power standby to fit standby energy regulationsPassive braking, freewheeling and automatic power downIntegrated pulse generator for standalone motionProduct InformationMotor Type: StepperNo. of Outputs: 1OutputsOutput Current: 2ADriver Case Style: QFNNo. of Pins: 28PinsSupply Voltage Min: 4.75VSupply Voltage Max: 29VOperating Temperature Min: -40°COperating Temperature Max: 125°C
