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 BP/M pin current at 6.1 V.
BP/M pin is not intended for sourcing supply current to external circuitry.
To ensure correct current limit, it is recommended that nominal 0.1 μF / 1 μF / 10 μF capacitors are used. In addition, the BP/M
capacitor value tolerance should be equal to or better than indicated below across the ambient temperature range of the target
application. The minimum and maximum capacitor values are guaranteed by characterization.
For current limit at other di/dt values, refer to Figure 24. Measurements made with device self-biased.
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
