Hi all,
this is maybe a silly question but I'm really not sure about this:
The BQ24450 spec (same as UC3906) states a parameter called
Vpre_rev: PRE-CHG reverse hold-off voltage
For UC3906 it's called trickle bias reverse hold-off voltage.
Now, what's the difference between that and the max. rated
reverse voltage at PRE-CHG/trickle bias pin?
I mean, if I could only apply up to 7V at this pin it would damage
the device as soon as I remove Vin and have a e.g. 12V battery
still attached. But this is how I understand this spec.
Thanks in advance,
Timo
