TMC260A-PA

TMC260A Double full bridge driver chip

TMC260A is One a Double full bridge driver chip，Suitable for bipolar, stepper motor drives. Internally integrated patented technology ， Sensorless Stall detection Features，Available in

function for position control without external sensors; This function also predicts the overload of the motor and is suitable for applications requiring high reliability. Integrated MOSFETs inside the chip, using the unique Low-RDS-ON technology to achieve low power consumption, high efficiency performance, strengthen the motor and driver's own cooling without external cooling equipment, even in the case of high external temperature can be achieved 1.7 A drive current output. The TMC260A's low power consumption, high efficiency, and small size make it the perfect choice for embedded motion control and even battery-powered devices. The integrated DAC function enables microstep control of current. The TMC260A can be connected via SPI serial interface. And STEP / DIR signal input control, in addition, the chip also has short-circuit, over temperature, under voltage, overload and other protection functions.
