STK672-740A-E

Ordering number : ENA1136B STK672-740A-E Thick-Film Hybrid IC 2-phase Stepping Motor Driver http://onsemi.com Overview The STK672-740A-E is a hybrid IC for use as a unipolar, 2-phase stepping motor driver with PWM current control. Applications Office photocopiers, printers, etc. Features Built-in overcurrent detection function (output current OFF). Built-in overheat detection function (output current OFF). If either overcurrent or overheat detection function is activated, the FAULT signal (active low) is output. Built-in power on reset function. Phase signal input driver activated with an active Low and incorporates a simultaneous ON prevention 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. Provides the output current cutoff ENABLE pin.
