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 allow up to 16 times microstepping via SPI, any resolution via analog control Mixed decay feature for smooth motor operation Slope control user programmable to reduce electromagnetic emissions Chopper frequency programmable via a single capacitor or external clock Current control allows cool motor and driver operation Internal open load detector 7V to 30V motor supply voltage More than 3000mA using 8 external MOS transistors External drivers can be added for higher motor voltages and higher currents (e.g. 75V, 10A) Only 4 external PMOS transistors required for unipolar operation 3.3V or 5V operation for digital part Low power consumption via low RDS-ON power stage Standby and shutdown mode available Copyright © 2002, TRINAMIC Microchips GmbH TMC239 DATA SHEET (V1.00 / Apr. 24th, 2003) 2 Life support policy TRINAMIC Microchips GmbH does not authorize or warrant any of its products for use in life support systems, without the specific written consent of TRINAMIC Microchips GmbH.
