STK672-642AN-E
Overview The STK672-642AN-E is a hybrid IC for use as a unipolar, 2-phase stepper motor driver with PWM current control. Applications - Office photocopiers, printers, etc. Features - Built-in overcurrent detection function, overheat detection function (output current OFF). - FAULT signal (active low) is output when overcurrent or overheat is detected. - Built-in power on reset function. - The motor speed is controlled by the frequency of an external clock signal. - 2 phase or 1-2 phase excitation switching function. - Phase is maintained even when the excitation mode is switched. - Rotational direction switching function. - Supports schmitt input for 2.5V high level input. - Incorporating a current detection resistor (0.089Ω: resistor tolerance 2%), motor current can be set using two external resistors. - The ENABLE pin can be used to cut output current while maintaining the excitation mode. - With a wide current setting range, power consumption can be reduced during...
