BQ76952: DSG MOS ON delay too long

Part Number: BQ76952

hi,

When Host(MCU) try to control DSG MOS Fet status from OFF to ON through I2C commands or DSGFet pin, the delay varies from 80 ms to 200 ms.

The detailed samples just like the following:

1) Host turns DSG MOS ON through DSG FET Pin:

Data1:80ms
Data2:173ms
Data3:205ms
Data4:94ms
Average:138ms

One of the signal capture is as following:

2) Host turns DSG MOS ON through I2C commands:

Data1:166ms
Data2:72ms
Data3:72ms
Data4:178ms
Data5:186ms
Average:134.8ms

When Host turns DSG MOS ON through TEST MODE, the delay will reduced to 1000- uS level.

The delay time is too high and unacceptable. Please help to improve it.

Thanks!
