Product Introduction

MS4982is a bipolar microstepping motor driver chip with built-in4bit DAC, supporting full-step,1/2，1/4，1/16, four steppingmodes; the chip hasrelativelylarge35V，±1.5Adriving capability.MS4982It is pulse-controlled stepping mode. EachSTEPpulse applied to thepin advances the motor by one microstep; no phase sequence table is needed, norhigh-frequency control lines or complex program control interfaces.

MS4982 It also features a rectifier with fixed current decay period, which canautomatically select the current decay mode: slow decay and mixed decay. In mixeddecay mode, it is fast decay during the initial decay period and slow decay for the remaining time. Thisdecay mode helps reduce motor noise, increase stepping accuracy,and reduce power consumption.

The internal synchronous rectification circuit reduces power consumption. It has built-in over-temperature protection,overcurrent protection, undervoltage protection, and short-circuit protection circuits, and the chip doesnot require a special power-on sequence.

MS4982It has a built-in5V LDOcircuit as an internal low-voltage powersupply, no external power supply is needed, and the logic interface is compatible with5V，3.3V TTLlevels.
