Hi Team,
The customer has two questions for DRV8860.
1. For Fault Register Reset question:
If the Data register is written 0 and the nFAULT pin is floating, is the OL(Open Load Detection) flag bit 1 or 0? At this time, execute the Fault Register Reset command and then read the fault register, is the OL(Open Load Detection) flag bit 1 or 0?
2. For the enable pin question:
The enable pin is needed to pull down the low logic when the registers can be read and written in the datasheet.
But the customer does a test. The test result shows a high level or a low level for the enable pin cannot affect the registers read / write operation.
That is the registers can be read and written correctly when the enable pin is a high level or a low level.
How to set the enable pin? If the enable pin is needed to pull down the low logic, will the output state for DRV8860 be changed?
