In MAX20710/30/34/43 datasheet, there is only one sentence mentioning the "Hiccup Overcurrent Protection". However there is no explanation how this hiccup mode works.
The correct behavior of the overcurrent fault response is:
1. When inductor current hits the valley current limit, the current clamping occurs. In this situation, turn-on of the high-side switch is prevented until the current falls below the threshold level. Therefore the inductor valley current is clamped at the valley current threshold level as below picture shows.
(CH1: Vout, CH2: VX, CH3: IL, CH4: STAT)
2. If after 5ms the OCP still exisits, the device enters hiccup-mode. The hiccup time is 45ms. In every 45ms the device will try to restart
3. During hiccup mode, if the device found the OCP condition is removed, the device powers up again.
