ELECTRICAL CHARACTERISTICS
Note 4: Both VCC3 and VCC5/VCC25/VCC18 can act as the supply depending
on which pin has the greatest potential.
Note 5: Measured from when input passes through the input threshold
(VRTX) until RST or COMPX passes through 1.5V.
Note 6: The output pins RST and COMPX have internal pull-ups to VCC3 of
typically 6
A. 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.
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 LTC1727E/LTC1728E are guaranteed to meet specified
performance from 0
°C to 70°C and are designed, characterized and
assured to meet the extended temperature limits of – 40
°C to 85°C
but are not tested at these temperatures.
