STK672-732AN-E Stepper Motor Driver IPM (Intelligent Power Module) Unipolar 2-Phase www.onsemi.com Overview The STK672-732AN-E is a IPM 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. Phase signal input driver activated with an active Low and incorpororates a simulataneous ON prevention function. Supports schmitt input for 2.5 V high level input. Incorporating a current detection resistor (0.141 : 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. Supports compatible pins with STK672-740AN-E.
