LP5306 Version 0.2 JUN.-2018

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 with an

excessive current. The LP5306

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

LP5306

is available in a space saving DFN-8 package.
