TMC236B-PA

电机驱动器/控制器, 步进电机, 2输出, 3.3 V至5 V电源, 34 V/1.1 A输出, PQFP-44

The TMC236B is a dual full bridge driver IC for bipolar stepper motor control applications. It 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. The low power dissipation makes the TMC236 an optimum choice for drives, where a high reliability is desired. Internal DACs allow microstepping as well as smart current control. The device can be controlled by a serial interface SPI™i or by analog / digital input signals. Short circuit, temperature, undervoltage and overvoltage protection are integrated.
