| POWER DR I V E R F O R S T E P P E R M O T O R S I N T E G R A T E D C I R C U ITS TMC2 36 Micr oste p Dr iver for up to 1.5A M A IN CH A R AC T ER IS T IC S INFO The TMC236 is a smart power microstepping driver for bipolar stepper motors. It provides an SPITM interface as well as the classical analog /digital control. A full set of protection and diagnostic features makes this device very rugged. The integrated low-RDS-ON TrenchFET(R) power MOSFETs give an extremely high efficiency and allow driving of a high motor current of up to 1.5A per phase without cooling measures even at high environment temperatures. The small footprint and high efficiency make the device a perINTERFACE * full protection and diagnostics * low power dissipation * 16 times microstepping via SPI, 64 times using additional shift register, even more via analog control * mixed decay for smooth operation * programmable slope control for low EME * internal or external chopper clock * standby and shutdown mode * easy-to-use SPITM interface * classical analog interface ELECTRICAL DATA fect solution for embedded motion control and even for battery powered designs. The evaluation can be done with the TMC246, as the only difference is the additional stallGuardTM feature. PACKAGE * up to 1500 mA coil current (peak) * 7V to 34V motor supply (TMC236A) * 3.3V or 5V operation for digital part * standard PQFP-44 package * RoHS compliant C/CLK TMC236 OSC IN A IN B 2x 4 bit DACs PWM control & Gate Driver Coil A internal Driver Stage Current monitoring Step Motor 10 mm SPI Control & Diagnostics PWM control & Gate Driver Temp / Volt protection Coil B ERROR 3.3 / 5V DC 7..34V DC internal Driver Stage OR DE R C O DE D E S C RI P T I ON TMC236A-PA TMC428A-EVAL 1.5A driver, PQFP-44 Evaluation board for TMC428, TMC246A and TMC249A with stallGuardTM www.trinamic.com - for detailed information and datasheets 11 |
