Part Number: DRV8263-Q1

Hi team,

What is the delay time of current sense?

Customer wants to know the delay time to adjust their algorithm.

Regards,

Peter

    Hi Peter,

    This timing will depend on the loads (caps, ADC, etc) on the IPROPI pin since this will slow the voltage rise time of the IPROPI pin. IPROPI is a current mirror so more capacitance on IPROPI increases the rise time.

    We do not have a spec for the delay that would be present only from the DRV826x device itself but something in the realm of ~10us would be reasonable.

    Regards,
