Application Scenarios & Design Considerations

Stepping Motor Driver IC

Alternative Part Number

  • LB1909MC --: Motor driver IC with similar function and supply voltage range, commonly used as a drop-in replacement in small motor drive applications.
  • BA6287F --: Single-channel motor driver in a similar package with comparable output current and voltage ratings, suitable functional substitute.
  • L293D --: Widely available dual H-bridge motor driver covering similar voltage and current requirements, though pinout differs so layout changes may be needed.
  • TB6612FNG --: Dual H-bridge motor driver in the same family class with similar voltage and current ratings, commonly used as a drop-in replacement for TA7774FG in small motor drive applications.
  • DRV8833 --: Dual H-bridge motor driver with comparable supply voltage range and output current, widely available and functionally similar to the TA7774FG.
  • L298N --: Classic dual H-bridge driver with higher current capability; usable as an alternative when board space allows and slightly higher voltage drop is acceptable.
