FEATURES
It supports more than 6000mA coil current. The low power dissipation makes the TMC249 an optimum choice for drives, where a high reliability is desired. With additional drivers, motor current and voltage can be increased. 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 TMC249 an optimum choice for drives, where a high reliability is desired. Internal DACs allow microstepping as well i 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.●
