between fast and slow decay current. The module
internally generates the phase sequence,
significantly reducing the burden on the controller.
Integration of a power MOSFET stage
significantly reduces both commutation and
conduction losses. The SPMD150STP offers
complete output protection against all types of
short conditions. The metal package acts as an
integrated heatsink, with no ventilation or
additional components required. The metal case
also isolates the inner circuit from external
agents, making the module suitable for operation
in harsh environments.
The STEVAL-SPMD150V1 supports the following
measurements and demonstrations: full/half-step,
microstepping, CW/CCW, control behavior, motor
stepper motors.

fully-protected solution to implement precise
position control, with high torque at rest, and
without the need for external components. The
module operates over a wide 12 V to 40 V input
voltage range and supports an output maximum
current of 1.5 A.
The SPMD150STP implements full/half-step and
microstepping driving capability, working at a
variable chopper frequency. It is possible to select
