Other Parts Discussed in Thread: DRV110
Hi,
We had issues peak ripple current with DRV110EVM Evaluation module.
Please waveform details as below.
Case 1: Peak to peak ripple current while valve on to off & off to on condition .
Case 2: Peak to peak ripple current while valve on-off condition
.
Setting with DREV110EM module:
1. Hold current set to 50mA @ 200K POT R5
2.Peak current set to 220mA @ 270k POT R4.
3.PWM frequency set to 200k @ 20KHZ POT R6.
observation: Valve current peak to peak ripple is more during valve on condition ,off-on /on-off condition.
Please let me know any clarification required further .
and do the needful as soon as possible.
