Comparing motor/valve power drivers - IBT2/4, MD13S, L298N

I’m wondering what the difference is between the L298N, IBT and MD13S.

To answer my own question, here are some basic comparisons.

L298N ($2.42 CDN)

  • Input voltage : 7.5V-46V
  • Current : 2A (3-4A short peak)
  • Input level : 5V
  • Max Freq : 40KHz
  • Notes : Considered “old” but cheap, allows individual control of each channel (4 ch)

IBT-2 ($9 CDN)

  • Input voltage : 6V-27V
  • Maximum Current : 43A
  • Input level : 3.3V-5V
  • Max Freq : 25KHz
  • Notes :

IBT-4 ($14.23 CDN)

  • Input voltage : 5V-15V
  • Maximum Current : 50A
  • Input level : 3.3V-12V
  • Max Freq : 200KHz
  • Notes :

MD13S ($16.40 CDN)

  • Input voltage : 6V-30V
  • Current : 13A (30A for 10s)
  • Input level : 3.3V-5V
  • Max Freq : 20KHz
  • Notes : Simple control IO, very efficient (no heatsink needed for 13A @ 25 deg C)

If anyone wants to add to this, let me know the details and I can edit this post.
