Hello ,
I have just tried couples of times to set this pin HIGH but until now i didn't succeeded.
I would require a 2nd opinion on this issue.
my configuration is for a 10s BMS
On this system i have tried the following setting to simulate an SOT over the SAFE pin :
Settings :
1.Enable_PF_A - SOT - 10 hex
2.Enable_PF_B - TS1 - 10 hex
3.PF -> SOT default 65°C with delay 5s
4.Manuf.Status Init -> 0170 hex (Safe_en;PF_en_LF_en;Fet_en)
5.SBS com -> 0131 hex -> VSCL0 set 1 (as is mentioned in other topics VScale is needed)
Wanted result was that SAFE_Pin is set to HIGH (Vdd)
I did actually recorded a change in PF_status as following
1. Safety _status _B >02 hex > OTD event
2.PF_Status_A_-> SOT event
3.Operation status _A -> 017b hex event
Note: i have tried also to get the same by setting also the Fuse PF_safe_A and B -> recorded the event as for a blowing fuse in BMS software
Questions :
1.Is it possible that i forget something to configure ?
2.Does the Safe_pin needs an Pull-up restor to Vdd?
