Figure 21. 5V Switch I-V Curve

9.3.3.3 PP_5V0 Current Sense

The current from PP_5V0 to VBUS is sensed through the switch and is available to be read digitally through the

ADC.

9.3.3.4 PP_5V0 Current Limit

The current through PP_5V0 to VBUS is limited to ILIMPP5V and is controlled automatically by the digital core.

When the current exceeds ILIMPP5V, the current-limit circuit activates. Depending on the severity of the over-

current condition, the transient response will react in one of two ways: Figure 22 and Figure 23 show the

approximate response time and clamping characteristics of the circuit for a hard short while Figure 24 shows the

shows the approximate response time and clamping characteristics for a soft short with a load of 2 Ω.
