Low cost microstep driver IC for bipolar steppermotors

The IMT 903 is a PWM chopper type sinusoidal micro step bipolar stepping motor driver IC.
A stepping motors can be controlled by a single low loss and highly integrated driver IC with 2,5A and 35V max.

Advantages

For one steppermotor with up to 2,5A and 35V max.
allows for space and cost savings with a maximum of functionality and a minimum of external components
microstep switching
selectable from 1/1, 1/2, 1/4, 1/8, (1/16) step enables smooth and constant running and reduces system resonance considerably .
low R_DSON = 0,22 Ohm
reduces power dissipation significantly and avoids system resonances
serial transmission protocol (e.g. SPI)
reduces the number of PINs
