45V, 1.5A Stepper Driver with Integrated Current Sense, 1/256 Microstepping and Advance Decay Mode

SGM42685.pdf

The SGM42685 is a stepper motor driver with power supply voltage up to 45V, available for various applications such as consumer, industrial, and medical equipment. Due to the fully integrated of power MOSFETs and current sense circuits, as well as the implementation of microstepping indexer and current regulator internally, only a small number of peripheral circuits are required to drive a stepper motor. The SGM42685 provides peak current driving capabilities of 1.5A.

The SGM42685 adopts a built-in current sense architecture, which ensures high current accuracy while eliminating external sampling resistors. The integrated indexer can reach up to 256 micro-steps, so as to achieve smooth and low noise driving effects. In addition to the traditional slow and mixed decay modes, the internal current regulator offers advanced smart tune ripple control to achieve smaller current ripple.

Universal STEP, DIR, and ENABLE interfaces are provided to control the motion of the stepper motor. By pulling down the nSLEEP pin, the driver can enter sleep mode to obtain ultra-low standby current. Protection functions are integrated such as under-voltage, short-circuit, over-current, and over- temperature, which is indicated through the nFAULT pin.

The SGM42685 is available in a Green TSSOP-24 (Exposed Pad) package.
