The TMC239A-SA from Trinamic Motion Control GmbH is an integrated circuit designed for driving two-phase bipolar stepper motors. It supports high motor currents up to 7A RMS and operates within a voltage range of 7V to 34V DC. The digital circuitry operates on 3.3V or 5V DC.
This driver IC provides advanced microstepping, offering up to 16x microsteps via SPI operation or up to 64x microsteps using analog voltage control for coil currents. It features an SPI interface for control and configuration, along with integrated protection mechanisms against overvoltage, overtemperature, and short circuits. Diagnostic features include overcurrent and open load detection.
The TMC239A-SA is housed in a 28-SOIC surface-mount package, making it suitable for various automation and control applications. Its design emphasizes low power dissipation through low RDS-ON power stages and includes features like mixed decay for smooth operation and slope control for reduced electromagnetic emissions.
Applications for the TMC239A-SA include textile machinery, office automation, printers, scanners, ATMs, cash recyclers, POS systems, antenna positioning, pumps, valves, lab automation, and liquid handling systems.
