DRV8718-Q1: DRV8718-Q1 OLSC time request

Tom Li53

Part Number: DRV8718-Q1

Hello,

How long it will take to finish the OLSC ? Is there a minimum time request for the OLSC operation? Based on our test, it needs about 100mS after set the OLSC to get the right register value. Thanks!

Hi,

Thank you for your question. Please refer this FAQ.

It requires to set PU/PD and read back VDS comparator output via SPI. Need to wait until output settle down by 3mA load current. It depends on output load condition. (The capacitance/motor inductor should exist, it takes time to settle down by 3mA current source/sink.)

So it depends on load condition for completion time.
