Ordering number : ENA2295 STK672-432AN-E Thick-Film Hybrid IC 2-phase Stepper Motor Driver http://onsemi.com Overview The STK672-432AN-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).  FAULT1 signal (active low) is output when overcurrent or overheat is detected. The FAULT2 signal is used to output the result of activation of protection circuit detection at 2 levels.  Built-in power on reset function.  A micro-step sine wave-driven driver can be activated merely by inputting an external clock.  External pins can be used to select 2, 1-2 (including pseudo-micro), W1-2, 2 W1-2, or 4W1-2 excitation.  The switch timing of the 4-phase distributor can be switched by setting an external pin (MODE3) to detect either the rise and fall, or rise only, of CLOCK input.  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 (0.152Ω: 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 standby.  No motor sound is generated during hold mode due to external excitation current control.  PWM operation is separately excited system. As for PWM phase the constant current control which shifts the phase of Ach Bch.  Supports compatible pins with STK672-430AN/-440AN/-442AN-E.  Specifications Absolute Maximum Ratings at Tc = 25C Parameter Maximum supply voltage 1 Maximum supply voltage 2 Input voltage Output current 1 Output current 2 Output current 3 Allowable power dissipation 1 Allowable power dissipation 2 Operating substrate temperature Junction temperature Storage temperature Symbol Vcc max VDD max Vin max IOP max IOH max IOF max PdMF max PdPK max Tcmax Tjmax Tstg Conditions No signal No signal Logic input pins 10μs 1 pulse (resistance load) VDD = 5V, CLOCK  200Hz 16pin Output current With an arbitrarily large heat sink.
