INTEGRATED CIRCUITSPOWER DRIVER FOR STEPPER MOTORS INFO MAIN CHARACTERISTICS www.trinamic.com – for detailed information and datasheets 10 mm TMC 236 Microstep Driver for up to 1.5A The TMC236 is a smart power microstepping driver for bipolar stepper motors. It provides an SPI™ interface as well as the classical analog/digital control. A full set of protection and diag nostic features makes this device very rugged. The integrated low-RDS-ON TrenchFET® 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 environ ment temperatures. The small footprint and high efficiency make the device a per- fect solution for embedded motion control and even for battery powered designs. The evaluation can be done with the TMC246, as the only differ- ence is the additional stallGuard™ feature. 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 INTERFACE easy-to-use SPI™ interface classical analog interface ELECTRICAL DATA up to 1500 mA coil current (peak) 7V to 34V motor supply (TMC236A) 3.3V or 5V operation for digital part PACKAGE standard PQFP-44 package RoHS compliant ORDER CODE DESCRIPTION TMC236A-PA 1.5A driver, PQFP-44 TMC428A-EVAL Evaluation board for TMC428, TMC246A and TMC249A with stallGuard™ TMC236 3.3 / 5V DC 7..34V DC IN A IN B ERROR SPI C/CLK Temp / Volt protection 4 bit DACs OSC Control Diagnostics PWM control Gate Driver Coil A internal Driver Stage internal Driver Stage Current monitoring PWM control Gate Driver Coil B Step Motor
