A little off the subject of braking, but on the subject of VHN3SP30 driver
chips.
I noticed on Pololu's site, they mention the VNH3SP30 is limited to a supply
voltage of about 16 volts due to shoot through issues. Anyone have any
comments on that?
I was looking at driving some 24 volt motors that peak around 10 amps and
average about 2 on my CNC laser. Currently I am using a Deventech MD22
controller, but want something I can directly control. Figuring I could get faster
response versus MD22 since it has its own processor that generates PWM given
I2C, Analog or Hobby Servo type signals (1.0 to 2.0 ms pulse width every 20 ms
or so).
