DS1336 Datasheet Afterburner Chip

Manufacturer: Dallas Semiconducotr

Overview: DS1336 Afterburner Chip www.dalsemi.com.

General Description

VCC/IN1 IN2 - IN5 OUT1 - 5 VBATIN VBAT01 VBAT02 PF, PF GND - +5V Input and Input 1 - Inputs 2 - 5 - Outputs 1 - 5 - External Battery Input - Diode Protected Battery Output - Low Voltage Drop Battery Output - Power-fail Inputs - Ground 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.

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 VCC to a battery backup supply when VCC falls out of tolerance.
