Features

AI Translation
  • The TMC246 / TMC246A / TMC246B is a dual full bridge driver IC for bipolar stepper motor control applications.
  • The integrated unique sensorless stall detection (pat. pend.) stallGuard™ makes it a good choice for applications, where a reference point is needed, but where a switch is not desired.
  • Its ability to predict an overload makes the TMC246 an optimum choice for drives, where a high reliability is desired.
  • The TMC246 is realized in a HVCMOS technology combined with Low - RDS - ON high efficiency MOSFETs (pat. pend.).
  • It allows driving a coil current of up to 1500mA even at high environment temperatures.
  • Its low current consumption and high efficiency together with the miniature package make it a perfect solution for embedded motion control and for battery powered devices.
  • Internal DACs allow microstepping as well as smart current control.
  • The device can be controlled by a serial interface (SPI™) or by analog / digital input signals.
  • Short circuit, temperature, undervoltage and overvoltage protection are integrated.
  • Sensorless stall detection stallGuard™ and load measurement integrated
  • Control via SPI with easy - to - use 12 bit protocol or external analog / digital signals
  • Short circuit, overvoltage and over temperature protection integrated
  • Status flags for overcurrent, open load, over temperature, temperature pre - warning, undervoltage
  • Integrated 4 bit DACs allow up to 16 times microstepping via SPI (can be expanded to 64 microsteps)
  • Any resolution via analog control
  • Mixed decay feature for smooth motor operation
  • Slope control user programmable to reduce electromagnetic emissions
  • Chopper frequency programmable via a single capacitor or external clock
  • Current control allows cool motor and driver operation
  • 7V to 34V motor supply voltage (A - type)
  • Up to 1500mA output current and more than 800mA at 105°C
  • 3.3V or 5V operation for digital part
  • Low power dissipation via low RDS - ON power stage
  • Standby and shutdown mode available
