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.
