Battery Charger Selection Guide
Selecting the right battery charger is critical for battery safety, performance, and lifetime. This guide covers key considerations for choosing MPS battery chargers. First, determine your battery chemistry and capacity. Li-ion/Li-polymer batteries require constant-current/constant-voltage (CC/CV) charging with specific voltage limits (typically 4.2V). Battery capacity determines charge current - typically 0.5C to 1C rate. A 2Ah battery charges at 1-2A. Next, choose topology: Linear chargers (MP2722) are cost-effective for small batteries (<2Ah) but generate heat. Switching chargers (MP2759) are more efficient and suitable for larger batteries. Consider input power source - USB (500mA/900mA/1.5A/3A), adapter, or wireless. USB chargers need input current limiting. Power path management allows instant-on operation even with dead batteries. Safety features are essential: JEITA-compliant charging, battery temperature monitoring, timer protection, and fault detection. I2C programmability provides flexibility for charge parameter adjustment.
