SGM42636
45V, 1.5A Stepper Driver with Integrated Current Sense, 1/256 Microstepping and Advance Decay Mode
The SGM42636 is a highly integrated bipolar stepper motor driver with 7V to 45V voltage range and full-scale current of 1.5A per winding respectively. It can be used in a verity of applications including consumer, industrial, and medical equipment. The integration of power MOSFETs, current sensing, microstepping indexer, and current regulators in these devices, allows compact system design with minimal number of peripheral components.
The integrated current sensing architecture ensures high current accuracy with no need for external lossy current sense resistors.
The popular STEP/DIR/ENABLE interface is used with an indexer that is capable of up to 256 micro-steps allowing smooth and low stepping noise operation.
The current regulators can be configured in several decay modes including the conventional slow and mixed decay, and the advanced dynamic decay and ripple control modes to minimize current ripple.
Sleep mode can be used to reduce the device current to the 1µA level by pulling the nSLEEP pin to the low state.
A comprehensive set of protection features including under-voltage, short-circuit, over-current and over- temperature is supported. The nFAULT indicator output reports occurrences of the faults.
The SGM42636 is available in Green TQFN-4×4-24L, TSSOP-24 (Exposed Pad) and TSSOP-28 (Exposed Pad) packages.
