The LPB1001 product is a highly integrated solution for Li-Ion battery protection. It includes advanced power MOSFETs, precision voltage detection circuitry and delay circuitry for all the protection functions required in battery applications, including overcharge, overdischarge, overcurrent and load short circuit protection. Its accurate overcharge detection voltage ensures a safe and efficient charging cycle. The low standby current allows for almost no battery current to be consumed during storage. The LPB1001 is available in an ultra-small TDFN-4 package. Its simple peripheral circuit requires only one external capacitor. This chip is suitable for any electronic device that requires long-term continuous power supply from a Li-Ion battery

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.

The LP5300 is an Over-Voltage-Protection (OVP) and Over-Current-Protection (OCP) device. The device will switch off internal MOSFET to disconnect VIN to VOUT to protect load when any of input voltage, input current over the threshold. The Over temperature protection (OTP) function monitors chip temperature to protect the device. The LP5300 is available in SOT-23-6L and SOT89 package. Standard products are Pb-free and Halogen-free.
