ELECTRICAL CHARACTERISTICS
temperature range, otherwise specifications are at T
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Hysteresis current must be 500nA minimum. Hysteresis current
may exceed 50µA, but accuracy is not guaranteed.
Note 3: HYS/CFG pin must be pulled to GND or V
resistor. See Applications Information for details.
