Customer found the delay timing was around 500ms from asserting the DFETOFF through MCU to DSG FETs off. At the B label in the below waveform, customer asserted the DFETOFF pin, and A label showed DSG FET was turned off with Vds increasing(CH1). Could you please help check whether the delay makes sense?
Hi Aki,
Please see the timing below for FET turn-on based on DFETOFF:
Although the timing is 250ms, this is for evaluation in NORMAL mode. SLEEP mode is a longer poll time. Please exit SLEEP mode by sending the 0x009A SLEEP_DISABLE() command before evaluation.
Best,
Andria
Hi Aki,
For the turn off see below:
You may try these settings to see if there is any improvement.
