Hello
I used BQ34Z950 IC to develop protection circuit for lithium ion battery pack 4s3p.
But facing problem regarding discharge Mosfet Drive Pin (DSG) of IC. This pin goes high (to 16v) whenever charging voltage is applied but there is no current flow in the battery pack. As applied voltage is removed pin goes again to 0v.
PACK pin shows the same behavior. While out off 5 leds 3 led state is ON for battery pack voltage 14.8v. These LED indication seems to be correct.
TOUT pin goes (2.5v)high after definite period of time.
Does device goes in shutdown mode? Is there any other reason for such behavior?
Thanks in advance
