NOTES:
A. For a threshold with a negative value, negative hysteresis is a decrease in magnitude of the corresponding threshold.
B. Total current consumption is the sum of I
C. Since the output MOSFET is switching, it is difficult to isolate the switching current from the supply current at the
D. BYPASS pin is not intended for sourcing supply current to external circuitry.
E. See typical performance characteristics section for BYPASS pin start-up charging waveform.
F. For current limit at other di/dt values, refer to current limit vs. di/dt curve under typical performance
G. This parameter is derived from characterization.
H. This parameter is derived from the change in current limit measured at 5X and 10X of the di/dt shown in the I
I. Auto-restart on time has the same temperature characteristics as the oscillator (inversely proportional to
