Motor Driver

Amplifies motor control signal e.g. from a microcontroller to control a motor.

Common Motor Drivers​

  • L3L293D
    • Controls 2 DC Motors
    • 4.5 - 36V
    • 600mA Continious Current, 1.2 A Peak Current
    • Transistor based
  • L298N
    • 4.5 - 46V
    • 2A Continous Current, 3 A Peak Current
    • Current Sense
    • Transistor based
  • TB6612FNG
    • 2.5 V - 15 V
    • 1.2 A Continous, 3.2 Peak Current
    • Produces little heat
    • MOSFET based
  • VNH2SP30
    • For one motor
    • 12V - 16V
    • Current 14 A continious, peak: 30 A
    • Produces little heat
    • MOSFET based

How to choose a driver​

  1. Choose driver based on the motor voltage
  2. The coninous current provided by the driver must be bigger than the motors stall current
  3. For battery powered usecases use MOSFET based drivers because they have less power drop
