KICKSTARTER OPERATION
A conceptual block diagram of the internal circuitry of
the DS1227 is illustrated in Figure 4 for reference. While
in an initial power down state, the DS1227 will sense ac-
tivity from an external stimulus applied to one of three
input pins and kickstart system power by applying volt-
age from the input power source to the primary V
CCO
output (V
CCO1
). Activity detected on any of the ON1,
RXIN, and SENSE pins initiates the kickstarting action.
When kickstarting occurs and the DS1227 is configured
for boost operation, the on-chip, step-up DC-to-DC con-
verter is started and the voltage on V
DCO
will be boosted
from its initial V
BAT
level to V
DCON
before V
CCO1
is
turned on. If the DS1227 is configured for voltage
Pass-Through operation, then the DC-to-DC converter
will remain disabled and voltage on the V
DCO
line will be
switched to the V
CCO1
pin immediately following the de-
tection of an active transition on a stimulus input.
