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
and I
when ENABLE pin is shorted to ground (MOSFET not switching)
and the sum of I
S2
and I
DSS
when ENABLE pin is open (MOSFET switching).
C. Since the output MOSFET is switching, it is difficult to isolate the switching current from the supply current at the
DRAIN. An alternative is to measure the BYPASS pin current at 6.2 V.
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
characteristics.
G. This parameter is derived from the change in current limit measured at 5X and 10X of the di/dt shown in the I
LIMIT
specification.
