Features
The TMC236 / TMC236A (1) is a dual full bridge driver IC for bipolar stepper motor control applications. It is realized in a HV
CMOS 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 i serial interface (SPI™ ) or by analog / digital input signals. Short circuit, temperature, under
voltage and over
voltage protection are integrated. Control via SPI with easy-to-use 12 bit protocol or external analog / digital signals Short circuit, over
voltage and over temperature protection integrated Status flags for overcurrent, open load, over temperature, temperature pre-warning, under
voltage Integrated 4 bit DACs allow up to 16 times microstepping via SPI (can be expanded to 64 microsteps) Any resolution via an...
