DESCRIPTION
The DS1259 Battery Manager Chip is a low-cost battery
management system for portable and nonvolatile elec-
tronic equipment. A battery connected to the battery in-
put 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 bat-
tery, the power fail signal is active to warn electronic re-
set circuits of the power status. Energy loss during ship-
ping and handling is avoided by pulsing reset, thereby
causing the battery to be isolated from other elements in
the circuits.
