Electrical Characteristics The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VCC = 3V to 6V, unless otherwise noted.

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: 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 VCC with an external
resistor. See Applications Information for details.
Note 4: Determined by design, not production tested. External circuits
pulling down on the FAULT pin must maintain the signal below VFAULT(LO)
for ≥1µs.
Note 5: Internal circuits may drive the OUTn pins higher than the Absolute
Maximum Ratings.
Note 6: RIN is the parallel combination of the two resistors forming the
resistive divider connected to the ON and IN1-IN4 pins.
