DESCRIPTION
The DS1336 Afterburner Chip is designed to provide
power switching between a primary power supply (V
CC
)
and a backup battery power supply (V
BAT
). Five V
CC
and two battery paths are provided which can be used
individually or in parallel to supply uninterrupted power
in applications such as SRAM networks. When used
with one of the Dallas power monitoring devices listed in
Section 10, Page 119, Table 1, the DS1336 allows a load
to be switched from its main power supply V
CC
to a bat-
tery backup supply when V
CC
falls out of toler-
ance. A user may selectively tie together any combina-
tion of the output pins to provide the desired high current
supply, providing up to 300 mA per OUT pin or a maxi-
mum of 1.5A. Depending upon the user’s backup sup-
ply load requirements, either of the V
BAT
outputs may be
tied to the OUT pins to supply current when V
CC
is out of
tolerance. The DS1336 switches back to the higher cur-
rent V
CC
from battery current when PF and PF become
inactive.
