1 Features
The TMC262 family is an energy efficient two phase stepper motor driver with high resolution
microstepping capability. It integrates the low resonance chopper spreadCycle for quiet and fast motor
operation. Its step and direction interface allows simple use. An SPI interface allows for
parameterization and diagnostics and can also be used to drive the motor. The TMC262 directly drives
four external N/P channel dual MOSFETs for motor currents up to 8A and up to 60V. Protection and
diagnostic features further reduce system cost and increase reliability. The TMC260 and TMC261
integrate a power stage for applications up to 40V resp. 60V and 1.7A. Their basic pinning is
compatible to the TMC236, allowing a simple upgrade path for existing applications. Its energy
efficiency and low power dissipation allow for a miniaturized design with minimum additional
infrastructure requirements making it a very cost effective driver.

ENN
19 DI VIO Enable not input for drivers. Switches off all MOSFETs.
CLK
21 DI VIO Clock input for all internal operations. Tie low to use internal

*) The OA and OB dual pin outputs directly are connected electrically and thermally to the drain of the
MOSFETs of the driver output stage. A symmetrical, thermally optimized layout is required to ensure
proper heat dissipation of all MOSFETs into the PCB. Use thick traces and enough vias for the motor
driver outputs.
