LTC1759
ELECTRICAL CHARACTERISTICS
The
G
denotes specifications which apply over the full operating temperature range (T
J
= 0
°
C to 100
°
C), otherwise specifications are
T
A
= 25
°
C. V
CC
= DCIN = 18V, V
BAT1, 2
= 12.6V, V
DD
= 3.3V unless otherwise specified.
Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
This limit is greater than the absolute maximum for the charger.
Therefore, there is no effective limitation on voltage when this option is
selected. If the charger is requested to charge with a higher voltage than
the nominal limit, the VOLTAGE_OR bit will be set.
Note 3:
Total system accuracy from SMBus request to output voltage or
output current.
Note 4:
Test Circuit #1.
Note 5:
Voltage accuracy is calculated using measured reference voltage,
obtained from V
SET
pin using Test Circuit #2, and VDAC resistor divider
ratio.
Note 6:
When supply and battery voltage differential is low, high oscillator
duty cycle is required. The LTC1759 has a unique design to achieve duty
cycle greater than 99% by skipping cycles. Only when V
BOOST
drops below
the comparator threshold, will TGATE be turned off. See Applications
Information section.
Note 7:
Power failure bit is set when the battery voltage is above 89% of
the power adapter voltage (V
DCIN
).
Note 8:
The charger provides wake-up current when a battery is inserted
into the connector, prior to the battery requesting charging current and
voltage. See Smart Battery Charger Specification (Revision 1.0), section
6.1.3 and 6.1.8.
Note 9:
In system start-up, C6 (boost capacitor) has no charge stored in it.
The LTC1759 will keep TGATE off, and turn BGATE on for 0.2
μ
s, thus
charging C6. A comparator senses V
BOOST
and switches to the normal
PWM mode when V
BOOST
is above its threshold.
Note 10:
Refer to Smart Battery Charge Specification (Revision 1.0),
section 6.1.2.
Note 11:
Maximum total external capacitance on RNR and THERM pins
is 75pF.
Note 12:
SMBus operation guaranteed by design from –40
°
C to 85
°
C.
