Since the output MOSFET is switching, it is diffi cult to isolate the switching current from the supply current at the
DRAIN. An alternative is to measure the BYPASS pin current at 6.1 V.
BYPASS pin is not intended for sourcing supply current to external circuitry.
See Typical Performance Characteristics section for BYPASS pin start-up charging waveform.
For current limit at other di/dt values, refer to Figure 25.
This parameter is derived from characterization.
This parameter is derived from the change in current limit measured at 1X and 4X of the di/dt shown in the I
Breakdown voltage may be checked against minimum BV
exceeding minimum BV
Auto-restart on time has the same temperature characteristics as the oscillator (inversely proportional to frequency).
