Application Scenarios & Design Considerations

BRIDGE DRIVER

Alternative Part Number

  • L293D --: Dual H-bridge motor driver in a DIP-16 package, widely available and functionally similar to the TA7291S for driving small DC motors.
  • SN754410 --: Quad half-H driver with pinout compatible with L293D, suitable as a drop-in style replacement for basic bidirectional motor control.
  • L298N --: Dual full-bridge motor driver with higher current capability, commonly used as a robust alternative when the TA7291S is unavailable.
