Description
This STEVAL-SPMD250V2 demonstration board
is designed for evaluating the performance and
the features of the SPMD250STP module. The
board works in conjunction with the PractiSPIN™
HW and the PractiSPIN™.spmd SW, which allow
the user to operate with the SPMD250STP
module.
The SPMD250STP is part of the EASY
POWER™ series of fully integrated modules
designed to drive bipolar permanent-magnet
stepper motors.
All EASY POWER modules offer an easy-to-use,
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 2.5 A.
The SPMD250STP implements full/half-step drive
capability, working at a fixed chopper frequency of
17 kHz. It is possible to select between fast and
November 2010

slow decay current. Home position indication is
available, as well as synchronization for multi-
motor applications. The module internally
generates the phase sequence, significantly
reducing the burden of the controller. Integration
of a power MOSFET stage significantly reduces
both commutation and conduction losses. The
SPMD250STP 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-
SPMD250V1 supports the following
measurements and demonstrations: full/half-step,
CW/CCW, control behavior, motor current
waveforms and measurements, movement
sequences.
