When the battery voltage is in the range from overdischarge detection voltage (VODP) to overcharge detection voltage (VOCP), and the CS pin voltage is in the range from the charger detection voltage (VCH) to discharge overcurrent detection voltage (VOI1), the IC turns both the charging and discharging control MOSFET on. This condition is called the normal status. Under this condition, charging and discharging can both be carried out freely. Caution: Discharging may not be enacted when the battery is first time connected. To regain normal status, CS and GND pin must be shorted or the charger must be connected. Overcharge Protection When the voltage of the battery cell exceeds the overcharge protection voltage (VOCP) beyond the overcharge delay time (TOC) period, charging is inhibited by turning off of the charge control MOSFET. The overcharge condition is released in two cases: 1. The voltage of the battery cell becomes lower than the overcharge release voltage (VOCR) through self-discharge. 2. The voltage of the battery cell falls below the overcharge protection voltage (VOCP) and a load is connected. When the battery voltage is above VOCP, the overcharge condition will not release even a load is connected to the pack. Halogen - free GM : SOT-23-6 Pb - free |
