The SY5322 is a highly integrated IC featuring input undervoltage and overvoltage protection, load current anomaly protection, and overtemperature protection. The SY5322 is used in the front end of charging circuits or low-voltage systems to protect low-voltage systems from abnormal input faults and can withstand abnormal input voltages up to 28V. When the input voltage exceeds the overvoltage protection threshold, the IC will quickly shut down the internal MOSFET within 1µs, preventing the backend low-voltage system from being affected by abnormally high input voltages; the IC can limit the input current through a resistor connected between ILIM and ground, preventing excessive input current to the low-voltage system; and the SY5322 also has chip overtemperature protection, which will also shut down the MOSFET and stop power supply when the chip temperature exceeds the overtemperature protection threshold.
The SY5322 is available in a SOT23-6 package and has a rated temperature range of -40°C to +85°C.
