The SY5323 is an overvoltage and overcurrent protection IC with low on-resistance 220 mΩ. The SY5323 can monitor the input voltage value in real time,
and when the input voltage exceeds the overvoltage protection threshold, it can quickly turn off the internal MOSFET within 50nS to protect the backend low-voltage system from abnormally high input voltage.
The IC supports input anti-reverse protection and the input voltage can support -30V.
The MOSFET will be turn off in 20uS, if the load current exceeds the limit threshold. The SY5323 enters hiccup mode, until the overcurrent condition removed.
The over current threshold is set by RILIM. When detecting that the temperature exceeds the over temperature threshold, the IC will turn off the internal MOSFET.
