Over Voltage and Over Current Protection IC
General Description
The LP5305 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 LP5305 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 LP5305 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 LP5305 is available in a space saving DFN-8 package.
