LTC692/LTC693
The
G
denotes specifications which apply over the full operating
temperature range.
Note 1:
Absolute maximum ratings are those values beyond which the life
of the device may be impaired.
Note 2:
All voltage values are with respect to GND.
Note 3:
For military temperature range, consult the factory.
Note 4:
The output pins of BATT ON, LOW LINE, PFO, WDO, RESET and
RESET have weak internal pull-ups of typically 3
μ
A. However, external
pull-up resistors may be used when higher speed is required.

Note 5:
The LTC692/LTC693 have minimum reset active times of 140ms
(200ms typically). The reset active time of the LTC693 can be adjusted
(see Table 2 in Applications Information Section).
Note 6:
The external clock feeding into the circuit passes through the
oscillator before clocking the watchdog timer (See BLOCK DIAGRAM).
Variation in the time-out period is caused by phase errors which occur
when the oscillator divides the external clock by 64. The resulting variation
in the time-out period is 64 clocks plus one clock of jitter.
Note 7:
The input pins of CE IN, OSC IN and OSC SEL have weak internal
pull-ups which pull to the supply when the input pins are floating.
