Tool/software:
Hi,
We test below condtions.
The MCU tries to control DSG MOSFET status from OFF to ON; the delay varies from 5 ms to 220 ms.
1. To pull low DFETOFF pin
2. Send the ALL_FETS_ON() i2c command
The MCU tries to control DSG MOSFET status from ON to OFF, the delay is about 300 uS.
1. To pull high DFETOFF pin
2. Send the ALL_FETS_OFF() i2c command
Comparing turning on DSG MOSFET and turning off DSG MOSFET, turning on DSG MOSFET takes too long.
We alredy read the previous discussion thread (e2e.ti.com/.../bq76952-dsg-mos-on-delay-too-long).
It looks like the AFE is doing the measurement loop in the normal mode, so maybe turning on the DSG MOSFET takes too long.
Is there any way to change the DSG MOSFET state from off to on in 10ms in normal mode? The test mode does not meet our product normal usage.
thsnks.
