General Description
The LP5305A 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 LP5305A 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 with an  excessive current. The LP5305A also monitors the  Li-ion battery voltage, when the battery voltage  exceeds 4.35V, the IC will turn off the MOS. Other features include over temperature protection  and under-voltage lockout (UVLO). The LP5305A  is available in a space saving DFN-8 package.
