I have recently ordered 1 x VNH3SP30 Motor Driver Carrier MD01B
I was just reading the charts and found below saying about the pwm,
VNH3SP30 and VNH2SP30 Comparison: VNH3SP30 VNH2SP30 Operating supply voltage (Vcc) 5.5 - 36 V* 5.5 - 16 V Maximum current rating 30 A 30 A MOSFET on-resistance (per leg) 34 mΩ 19 mΩ Maximum PWM frequency 10 kHz 20 kHz Current sense none approximately 0.13 V/A Over-voltage shutoff 36 V* 16 V minimum (19 V typical) Time to overheat at 20 A** 8 seconds 35 seconds Time to overheat at 15 A** 30 seconds 150 seconds Current for infinite run time** 9 A 14 A
* Manufacturer specification. In our experience, shoot-through currents make PWM operation impractical above 16 V.
** Typical results using Pololu motor driver carrier with 100% duty cycle at room temperature.
Does this mean if I want to PWM (vary the speed) of 24v actuators under load, will this work correctly with this VNH3SP30 board? or will it 'jump' voltage and not work How/What would you recommend please?
Thanks in advance, Galen
