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
