Figure A.1 SYM22801 Mechanical Drawing
A.2 Electrical Characteristics
The SYM22801 maximum power requirements, including SCSI
TERMPWR, under normal operation are as follows:
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
4 A is sustained no longer than 30 seconds before the self-resetting
TERMPWR short circuit protection device opens.
The PCI PRSNT1# and PRSNT2# pins are set to indicate a 15 W
maximum configuration.
