A.1.2 Electrical Characteristics
The SYM22902 maximum power requirements that include SCSI
TERMPWR (termination power) under normal operation are:
The PCI
PRSNT1
and
PRSNT2
pins are set to indicate a 7.5 W maximum
configuration.
Under abnormal conditions, such as a short on SCSI TERMPWR, + 5 V
current may be higher. At temperatures of at least 25
°
C, a current of
8 A is sustained no longer than 0.5 seconds before the self-resetting
TERMPWR short circuit protection device opens.
