Product Overview

The TMC239A-SA is a dual full-bridge Driver IC for bipolar stepper motor control applications. It has protection, diagnostics and SPI interface. It 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™) or by analogue/digital input signals. Short-circuit, temperature, under-voltage and over-voltage protection are integrated.
  • More than 6000mA using 8 external MOS transistors (4A RMS)
  • Control via SPI with easy-to-use 12-bit protocol or external analogue/digital signals
  • Short-circuit and over-temperature protection integrated
  • Over-voltage protection integrated
  • Status flags for overcurrent, open load, over-temperature, temperature pre-warning and under-voltage
  • 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
  • Up to 58V motor supply voltage using a few additional low cost components
  • External drivers can be added for higher motor voltages and higher currents (e.g. 50V/5A)
  • Only 4 external PMOS transistors required for unipolar operation
  • Low power dissipation via low RDS-ON power stage
  • Standby and shutdown mode available
  • 7 to 34V Motor supply voltage
