STK672-540 Overview
ENA0754A STK672-540 Thick-Film Hybrid IC 2-phase Stepping Motor Driver http://onsemi. Overview The STK672-540 is a hybrid IC for use as a unipolar, 2-phase stepping motor driver with PWM current control. Applications Office photocopiers, printers, etc.
STK672-540 Key Features
- The motor speed can be controlled by the frequency of an external clock signal
- 2-phase excitation or 1-2 phase excitation is selected according to switching the state of the MODE pin (low or high)
- The phase is maintained even if the excitation mode is switched in the middle of operation
- The direction of rotation can be changed by applying a high or low signal to the CWB pin used to select the direction
- Supports schmitt input for 2.5V high level input
- Incorporating a current detection resistor (0.11Ω: resistor tolerance ±2%), motor current can be set using two external
- Equipped with an ENABLE pin that, during clock input, allows motor output to be cut-off and resumed later while
