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 Table 1, the DS1336 allows a load
to be switched from its main power supply V
CC
to a battery backup supply when V
CC
falls out of
tolerance. A user may selectively tie together any combination of the output pins to provide the desired
high current supply, providing up to 300 mA per OUT pin or a maximum of 1.5A. Depending upon the
user鈥?backup supply load requirements, either of the V
BAT
outputs may be tied to the OUT pins to supply
