Features
The TMC239 / TMC239A (1) is a dual full bridge driver IC for bipolar stepper motor control applications. The TMC239 is realized in a HVCMOS technology and directly drives eight external LowRDS-ON high efficiency MOSFETs. It supports more than 6000mA coil current. The low power dissipation makes the TMC239 an optimum choice for drives, where a high reliability is desired. With additional drivers, motor current and voltage can be increased. The driver transistors can be chosen depending on output current or environment temperature. 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 .
