Part Number: DRV8305-Q1 DRV8305NQPHPRQ1
Our csutomer did EMI test but their system.test result is attached.
EMI test result.xlsx
Large noise is found at DRV8305NQPHPRQ1.
When EN_GATE is high,large noise is found.
When EN_GATE is low also large noise…
Part Number: DRV8305-Q1 Please let us know charge pump block power up timing.
If wake and EN_GATE are low,is Charge pump block powered up regardless of the status of wake and EN_GATE ?
