Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2.
Battery voltage must be adequate to drive gates of power path
P-channel FET switches. This does not affect charging voltage of the
battery, which can be zero volts during wake-up charging.
Note 3.
DCIN, BAT1, BAT2 are held at 12V and GDCI, GB1I, GB2I are
forced to 10.5V. SCP is set at 12V to measure source current at GDCI,
GB1I and GB2I. SCP is set at 11.9V to measure sink current at GDCI, GB1I
and GB2I.

compensation components.
Note 6.
The LTC1760C is guaranteed to meet specified performance from
0

C to 70
°
C and is designed, characterized and expected to meet specified
performance at –40
°
C and 85

C, but is not tested at these extended
temperature limits.
Note 7.
Charger servos to the value reported by a Voltage() query. This is
the internal cell voltage measured by the battery electronics and may be
lower than the terminal voltage. See “Operation Section 3.6” for more
information.
