DS1336 Datasheet PDF - Dallas Semiconductor -> Maxim Integrated

DESCRIPTION
The DS1336 Afterburner Chip is designed to provide power switching between a primary power supply(VCC) and a backup battery power supply (VBAT). Five VCC and two battery paths are provided which can be used individually or in parallel to supply uninterrupted power in applications such as SRAM networks.

FEATURES
Provides power switching of up to 1.5 amps at voltages between 3.0 and 5.0 volts
Five separate power switches
Selectable battery switches for use with
battery-backed systems
Very low on impedance of 0.7O
Battery backup current of 4 mA
Diode-isolated battery path
Available in 16-pin DIP or 16-pin SOIC surface
mount package
Low voltage drop battery path
Connects directly to a variety of Dallas Semiconductor devices, adding increased switching capability for large battery backup current applications
