DESCRIPTION

The DS1336 Afterburner Chip is designed to provide power switching between a primary power supply

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

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
