DESCRIPTION
The device achieves up to 3A of charge current (ICC) with any battery regulation voltage (VBATT_REG). The device operates under a maximum 36V DC input voltage and hold-off voltage up to 45V. When an input power supply is present, the MP2658 charges the battery with four phases: trickle charge, pre-charge, constant current (CC) charge, and constant voltage (CV) charge. The device can be configured to different precharge to fast charge thresholds and different charge termination modes via the external pins. This allows the MP2658 to support super capacitor charging, as well as charging for different battery chemistries. Power management is based on the input current (IIN) and input voltage (VIN). If IIN exceeds the preset input current limit, or if VIN drops to the preset input voltage limit, the MP2658 automatically decreases the charge current to protect the input power supply from an overload. To guarantee safe operation, the MP2658 offers robust protection features such as battery overvoltage protection (OVP), battery temperature sensing and protection, thermal shutdown, and a charging safety timer.
