DRV8243-Q1: Questions about off-state diagnostics

Grey Guo

Part Number: DRV8243-Q1

Tool/software:

Hi team,

My customer has some questions about off-state diagnostics of DRV8243-Q1. Could you help reply?

What's the filter time after changing EN/PH configuration?
When device is off, customer wants to do periodic off-state diagnosis (ms level) continuously? They are concerned that it may affect the life of device. Do you see any impact here?
Hong long is it recommended to reserve to read OLP CMP after EN/PH is changed?

Best Regards

Grey

Hi Grey,

Thank you for your question.

1. Internal logic delay/filter should exist (may be ~us), but normally external load has capacitor and inductor. L/C delay could be more(xx ms).

2. No concern. Internal PU/PD is ~1Kohm resistive load.

3.It highly depends on external capacitor and inductor. Customers need to check on their bench. Normally all customers do it by themselves.
