Product Summary

The IMT901 is a PWM chopper type sinusoidal micro step bipolar stepping motor driver. Sinusoidal micro step operation is generated by means of built-in hardware and is outputted for operation by clock signal inputting.

Parametrics

IMT901 absolute maximum ratings: (1)Supply voltage VCC: 5.5V; (2)VM: 40V; (3)Output current lout: 1.5A (AVE), 2.5A (peak); (4)Power dissipation Pd: 4W/40W without/with heat sink TC=85℃; (5)Operation temp.: -40℃ to 85℃; (6) Storage temp.: -55℃ to 150℃.

Features

IMT90 features: (1) only one IC for power and logic (up to 2.5A/phase) reduces considerably space, assembly time and cost of a microstep driver with a max. Functions yet with a min. of ext. components; (2) selectable from: 1/1-, 1/2-, 1/4-, 1/8-Step enables individual application-related microstep switching, smooth and constant running and reduces considerably system resonance; (3) Current down system or current zeroing reduces or eliminates motor power losses and heating during standstill.
