Fuman Power Chip

DW 01 A series circuit is a high-precision single rechargeable lithium battery over-charge and over-discharge protection circuit, it sets high-precision over-voltage charging protection, over-voltage discharge protection, over-current discharge protection and other performance in one. In normal condition, the VDD end voltage of DW 01 A is between the overvoltage charge protection threshold (VOC) and the overvoltage discharge protection threshold (VOD), and the VM detection end voltage is between the charger detection voltage (VCHG) and the overcurrent discharge protection threshold (VEDI), and the COUT end and DOUT end of DW 01 A output a high level, which is a high level to connect the external charge control N-MOS tube Q1 and the discharge control N-MOS tube Q2 respectively. At this time, you can either charge the battery with the charger or discharge the battery through the load.
