temperature range, otherwise specifi cations are at T
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
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 3μA. 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 timeout period is caused by phase errors which occur
when the oscillator divides the external clock by 64. The resulting variation
in the timeout 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 fl oating.
