PIN ASSIGNMENT
DESCRIPTION
The DS1259 Battery Manager Chip is a low-cost battery management system for portable and nonvolatile
electronic equipment. A battery connected to the battery input pin supplies power to CMOS electronic
circuits when primary power is lost through an efficient switch via the V
CCO
pins. When power is supplied
from the battery, the power-fail signal is active to warn electronic reset circuits of the power status.
Energy loss during shipping and handling is avoided by pulsing reset, thereby causing the battery to be
isolated from other elements in the circuits.
