Fuman Power Chip

The DW02R series circuit is a single section built-in MOSFET rechargeable lithium battery protection circuit, which combines high-precision overvoltage charging protection, overvoltage discharge protection, overcurrent discharge protection and other performance in one。Under normal conditions, the VDD terminal voltage of DW02R is between the overvoltage charging protection threshold (VOC) and the overvoltage discharge protection threshold (VOD), and its VM detection terminal voltage is between the charger detection voltage (VCHG) and the overcurrent discharge protection threshold (VEDI). At this time, DW02R conducts the built-in N-MOS transistor. At this time, the charger can be used to charge the battery or the load can be used to discharge the battery
