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 A Out, QFN-28 Product Overview The TMC2208 are ultra-silent motor driver ICs for two phase stepper motors. Their pinning is compatible to a number of legacy drivers. TRINAMICs sophisticated stealthChop2 chopper ensures noiseless operation, maximum efficiency and best motor torque. Its fast current regulation and optional combination with spreadCycle allow for highly dynamic motion. Integrated power-MOSFETs handle motor current up to 1.4A RMS. Protection and diagnostic features support robust and reliable operation. A simple to use UART interface opens 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 setting Smooth Running 256 microsteps by microPlyer™ interpolation stealthChop2™ silent motor operation spreadCycle™ highly dynamic motor control chopper Low RDSon LS 280mR & HS 290mR (typ. at 25°C) Voltage Range 4.75… 36V DC Automatic Standby current reduction (option) Internal Sense Resistor option (no sense resistors required) Passive Braking and Freewheeling Single Wire UART & OTP for advanced configuration options Integrated Pulse Generator for standalone motion Full Protection & Diagnostics Product Information: Motor Type: Stepper No. of Outputs: 1Outputs Output Current: 1.4A Driver Case Style: QFN No. of Pins: 28Pins Supply Voltage Min: 4.75V Supply Voltage Max: 36V Operating Temperature Min: -40°C Operating Temperature Max: 125°C
