LTC1726
Electrical Characteristics
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: The LTC1726E is guaranteed to meet performance specifications
from 0°C to 70°C. Specifications over the –40°C to 85°C operating
temperature range are assured by design, characterization and correlation
with statistical process controls.
Note 4: Both VCC3 and VCC25/VCC5 can act as the supply depending on
which pin has the greatest potential.
Note 5: Timing measured with respect to RST passing through 1.5V.
Note 6: The output pin RST has a weak internal pull-up to VCC3 of typically
6µA. However, external pull-up resistors may be used when faster rise
times are required or for VOH voltages greater than VCC3.
Note 7: The VCC5 reset override voltage is valid for an operating range less
than approximately 4.15V. Above this point the override is turned off and
the VCC5 pin functions normally.
