DESCRIPTION
The TMC262 driver for two-phase stepper
motors offers an industry-leading feature
set, including high-resolution micro-
stepping, sensorless mechanical load
measurement, load-adaptive power
optimization, and low-resonance chopper
operation. Standard SPI™ and STEP/DIR
interfaces simplify communication. The
TMC262 drives four external N- and P-
channel dual MOSFETs for motor currents
up to 8A and up to 60V. Integrated
protection and diagnostic features support
robust and reliable operation.
High integration, high energy efficiency
and small form factor enable miniaturized
designs with low external component
count for cost-effective and highly
competitive solutions.
