It is realized in a HVCMOS technology and directly drives eight external Low-RDS-ON high efficiency MOSFETs. The driver transistors can be chosen depending on output current or environment temperature. Its low current consumption and high efficiency together with the miniature package make the TMC239 a perfect solution for embedded motion control and for battery powered devices. It supports more than 3000mA coil current. With additional drivers, motor current and voltage can be increased. Internal DACs allow microstepping as well as smart current control. The device can be controlled by a serial i interface (SPI™ ) or by analog / digital input signals. Short circuit, temperature and undervoltage protection is integrated. Control via SPI with easy-to-use 12 bit protocol or external analog / digital signals Short circuit and over temperature protection integrated Status flags for overcurrent, open load, over temperature, temperature pre-warning, undervoltage Integrated 4 bit DACs allo...
