TMC262 Driver pre-stage

The TMC262 is an integrated stepper motor solution for Laboratory Automation, 3D-Printing, Scanners and other automated equipment applications. The device is capable of driving up to a gate current of 40mA and is powered by Trinamic StallGuard2™, CoolStep™, SpreadCycle™, MicroPlyer™ technology. TMC262 is designed for a supply voltage of 9...60V. The device provides a SPI and S/D interface.

The new TMC262C improves motor silence and adds low side short protection. The C-version is recommended for new designs.
