Part Number:LMD18200
We are developing a control board with LMD18200 motor driver for a welding equipment application [wire feeder].
The equipment as two functional operative work. In the first one the motor current in costant around 0.6 A max, while in the others the equipment work in “pulsed” mode where the motor is activated first in one direction for 300 ms, then in other direction for 200ms. That generates current pulse with peak of 10A and exponential decrease where current value get 0.6 A in around 150ms. RMS current value is around 4A.
The question concern which bypass value capacitors is/are suggested for LMD18200 Vs power supply. LMD18200 is supplied by a 42 V rail.
Thank you for your support.
