Power down signal input terminal
After input “H” level, Latch 3 will be set, DOUT=”H” level, and OCV=”L” level.
At this time, all battery connecting terminal will be released, and all bias will be
set OFF.
PF signal output terminal
Remoting ON signal input terminal
After input “L” level, the bias of over-charge detection block will be set OFF. At
this time, DOUT and COUT value will be equal to “H” level.
