DS1227
022698 20/20
NOTES:
1. Applicable only when Boost mode operation is in effect.
2. Applicable only when Pass Through mode operation is in effect.
3. Valid when 2.5V < V
DCO
< 5.0V.
4. Measured with Boost Mode operation in effect; I
CCO1
= I
CCO2
= I
CCO3
= I
CCO4
= 0. This value represents the
amount of current drawn by the DS1227 itself during and does not include current supplied on the I
CCO
out-
puts nor does if boost operator includes inefficiencies of DC-to-DC conversion.
5. Input transition current on the INT/ACK pin is specified to indicate the amount of current required to switch the
pin from a high to a low or from a low to a high condition. Once the pin has switched states, then the leakage
current specification is applicable.
6. ON1 and RXIN have internal weak p-channel pull-up devices.
7. When BOOST operation is in effect, the total combined current supplied out of V
CCO1
, V
CCO2
, V
CCO3
, and
V
CCO4
is limited by the V
DCI
peak current.
8. Actual efficiency is dependent on external discrete component characteristics.
9. Battery replacement in the boost mode requires the discharge of the capacitor attached to V
DCO
(pin 5). The
following, or similar, circuit is recommended (see Figure 11).
