Trinamic (TMC2208-LA-T) Motor Driver/Controller, UART, 1 Output

Motor Driver/Controller, Stepper, UART, 1 Output, 4.75 V to 36 V Supply, 1.4 AOut, QFN-28Product OverviewThe TMC2208 are ultra-silent motor driver ICs for two phase stepper motors.Their pinning is compatible to a number of legacy drivers. TRINAMICssophisticated stealthChop2 chopper ensures noiseless operation, maximumefficiency and best motor torque. Its fast current regulation and optionalcombination with spreadCycle allow for highly dynamic motion. Integratedpower-MOSFETs handle motor current up to 1.4A RMS. Protection and diagnosticfeatures support robust and reliable operation. A simple to use UART interfaceopens up more tuning and control options.2-phase stepper motors up to 2A coil current (peak)STEP/DIR Interface with 2, 4, 8, 16 or 32 microstep pin settingSmooth Running 256 microsteps by microPlyer interpolationstealthChop2 silent motor operationspreadCycle highly dynamic motor control chopperLow RDSon LS 280mR & HS 290mR (typ. at 25°C)Voltage Range 4.75 36V DCAutomatic Standby current reduction (option)Internal Sense Resistor option (no sense resistors required)Passive Braking and FreewheelingSingle Wire UART & OTP for advanced configuration optionsIntegrated Pulse Generator for standalone motionFull Protection & DiagnosticsProduct Information:Motor Type: StepperNo. of Outputs: 1OutputsOutput Current: 1.4ADriver Case Style: QFNNo. of Pins: 28PinsSupply Voltage Min: 4.75VSupply Voltage Max: 36VOperating Temperature Min: -40°COperating Temperature Max: 125°C
