2.12 Hiccup Mode Current Limit

Figure 2-17, Figure 2-18, and Figure 2-19 show the TPS54824EVM-779 hiccup mode current limit feature. When an overcurrent event occurs, the TPS54824EVM-779 shuts down and restarts. Figure 2-17 shows the restart sequence in an overcurrent condition. Figure 2-18 shows the TPS54824EVM-779 entering hiccup mode and Figure 2-19 shows the TPS54824EVM-779 exiting hiccup mode.
