Other Parts Discussed in Thread: DRV110
Hi,
We had issues of peak ripple current with DRV110EVM Evaluation module (valve load ).
we are observed the peak current at the time of valve on condition ,valve on/off & off/on conditions.
Please waveform details as below.
case 1:(Peak current waveform 1)
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.
