Application Scenarios & Design Considerations

4-PHASE STEPPING MOTOR DRIVE FOR UNIPOLAR CONSTANT-CURRENT CHOPPER DRIVER

Alternative Part Number

  • STK6982B --: Same STK69xx series dual power amplifier IC with nearly identical pinout and supply voltage ratings, commonly used as a direct substitute for STK6981B.
  • STK6983B --: Higher-power sibling in the same STK698x family with compatible pin arrangement and similar application circuit, suitable when slightly higher output is acceptable.
  • STK6961B --: Related STK69xx audio power amplifier with comparable supply and output characteristics, usable as a functional replacement with minor circuit adjustment.
  • STK672-440B --: Successor stepper motor driver IC from the STK672 series, functionally similar to the STK6981B and available from the former Sanyo semiconductor line now under ON Semiconductor.
  • TB6560AHQ --: Widely used bipolar stepper motor driver with comparable current and voltage ratings, commonly used as a replacement in designs that used the STK6981B.
  • L298N --: Classic dual H-bridge motor driver that can replace the STK6981B in many applications, though it requires external diodes and may need heatsinking.
  • TDA7294 --: Popular DMOS audio power amplifier IC offering comparable output power and voltage ratings, usable as a functional alternative with appropriate heatsink and circuit adaptation.
  • TDA7265 --: Popular dual audio power amplifier IC with similar output power class and supply range, usable as a functional replacement with minor circuit adaptation.
