Preliminary Datasheet LP5306 Over Voltage and Over Current Protection IC General Description The LP5306 is a highly integrated circuits, it used to protect low voltage system from abnormal high input voltage.
The IC continuously check the input voltage, the input current, and the battery voltage.
When the protection status is occur, the power MOS will turn off at the same time.
The LP5306 is safety devices to ensure worked against accidents.
In case of the input voltage exceeds a OVP threshold voltage level, the power MOS will turn off within 1μs.
The current limit can is adjustable by external resistor between ISET and GND.
And the current is also limited to prevent charging the battery ...
