myecpro-laptop battery

Batteries contain a lot of battery protection circuit, if more than the maximum battery voltage, the circuit connecting thehp battery temporarily disconnected.

Bq24314 chip implementation with security protection - a complete front-end protection of lithium-ion battery charger.

Bq24314 chip with integrated power FET; Vin great value for 30V; OCP programmable currents up to 15A; battery OVP for 4.35V; have fault indication features.

The chip provides for the protection of three variables, namely, input over-voltage and input over-current and  HSTNN-DB02 battery over-voltage; 30V input voltage greatly; for the current transient caused by an error has a higher trigger immunity; thermal shutdown, that is, fault status display with the current listing of the minimum solution. bq24300 and bq24314 charger front-end product line circuit for charging of handheld devices to provide system protection. The compact size of the safety circuit can provide three-tier protection function, that is, people over-voltage Des, Des person over-voltage protection and toshiba PA3399U-1BRS  batttery  over-current state.
